Earthquakes that cause extensive damage occur frequently in Japan, the most recent being the Noto Peninsula earthquake on January 1, 2024. To facilitate such a recovery, we introduce a community-based participatory research program implemented through cooperation between universities and local communities after the 2011 Great East Japan Earthquake. In this project, the university and the town of Shichigahama, one of the affected areas, collaborated to hold annual workshops in the target area, which evolved into a climate monitoring survey. Even in Japan, where disaster prevention planning is widespread, various problems arise in the process of emergency response, recovery and reconstruction, and building back better when disasters occur. As is difficult for residents and local governments to solve these problems alone, it is helpful when experts participate in the response process. In this study, we interviewed town hall and university officials as representatives of local residents regarding this project and discussed their mutual concerns. The community-based participatory research framework developed in the Shichigahama project could be used in the recovery from the Noto Peninsula Earthquake as well as in future reconstruction and disaster management projects.

An earthquake with a moment magnitude of 7.5 (Mw) struck the northern Noto Peninsula, Ishikawa Prefecture, Japan, at 16:10 local time on January 1, 2024. This earthquake triggered a tsunami that propagated along the coastline of Ishikawa, Toyama, and Niigata Prefectures facing the Sea of Japan and significantly damaged coastal communities and infrastructure. Approximately 70 researchers from 23 universities or other institutes throughout Japan formed a joint research group to conduct a post-tsunami survey along a 340 km stretch of the coast. Based on the watermarks and traces of the tsunami, the inundation and run-up heights were surveyed using total stations, automatic optical levels, laser range finders, and a real-time kinematic (RTK) Global Navigation Satellite System (GNSS). The tidal correction was adjusted using astronomical tidal tables. In total, 303 survey records have been compiled, generating the NP2024TS (Noto Peninsula 2024 Tsunami Survey) dataset. This dataset provides comprehensive information on the inundation and run-up heights of the tsunami, which is useful for understanding tsunami characteristics and validating numerical tsunami models.

Abstract A moment magnitude (M_w) 7.5 earthquake occurred on January 1, 2024, at the northern tip of the Noto Peninsula, Central Japan, triggering a large tsunami. Seismological and geodetic observations revealed the rupture of mapped submarine active faults. While proximal segment ruptures have been well resolved by previous research, far offshore segments have posed challenges for onshore-based inversions. This emphasizes the necessity for a comprehensive study on the fault through tsunami modeling. Here, we aimed to examine tsunami propagation and inundation using four different fault models to identify the general characteristics of the tsunami source and evaluate the complexities of earthquake- and submarine landslide-induced tsunamis. We identified the simultaneous rupture of two active fault systems as the most suitable model for explaining observed tsunami height and inundation; however, some inconsistencies with observations remained. The propagation process did not follow a concentric pattern but aligned with bathymetric heterogeneity. The findings also suggested potential amplification effects responsible for the devastation of the coast of Iida Bay and indicated a possible submarine landslide in southern Toyama Bay. The findings of the present work could benefit the exploration of a more realistic tsunami source model, considering the differences between observations and simulations. Such efforts, in collaboration with paleotsunami research, can contribute to the improved assessment of hazards from submarine active faults.

Abstract This study explored closed-circuit television (CCTV) networks in northeastern Toyama Prefecture, Japan, as a new data source for tsunami detection following the 2024 Noto Peninsula earthquake. We analyzed CCTV footage and extracted time-series water level fluctuations at Yokoyama, Shimoiino, and Ekko. Spectral analysis of these waveforms revealed several long-period peaks (more than 100 s) in power spectral density (PSD), suggesting the presence of tsunami components. Notably, relatively large PSD peaks at approximately 5–10 min were observed at all CCTV locations in this study and at offshore wave observation points (Tanaka and Toyama). At Yokoyama, a maximum run-up of approximately 3 m was confirmed around 16:28. Although water level fluctuations at Shimoiino and Ekko were detected, identifying tsunami components proved challenging due to their small magnitude compared to other wave components. Despite these challenges, this study demonstrates the potential of CCTV networks for tsunami detection, and further research is needed to achieve real-time detection.

The World BOSAI Forum 2023 (WBF2023), held in March 2023 in Sendai, Japan, was successfully convened as a global platform for practical discussion of disaster risk reduction issues in a free and dynamic manner, in contrast to the United Nations, where national interests collide, or academic conferences where experts gather. In particular, we aimed to disseminate the knowledge and lessons learned from the 2011 Great East Japan Earthquake and Tsunami (GEJET) to the world and share the knowledge and lessons with Japan. We would like to take this opportunity again to express our heartfelt gratitude to all those who participated in the sessions, exhibitions, posters, and flash talk presentations, as well as to the many locals who attended the event. According to the World BOSAI Forum [1], the WBF2023 was attended by 5,412 people over 3 days, including 1,335 pre-registrants from 40 countries and regions, on-site registrants, and EXPO participants. It included 30 oral sessions, 7 conferences, 50 poster sessions, 33 flash talk presentations, and 33 exhibition booths, where tangible solutions for disaster risk reduction were discussed through dialogue among international organizations, governments, academia, the private sector, NGOs, and citizens. At the forum, Tohoku University hosted 4 sessions and co-hosted 10 sessions, which introduced the role of Tohoku University and the International Research Institute of Disaster Science as well as their contributions to the processes of recovery and reconstruction from the 2011 GEJET. Finally, the forum came up with recommendations for a Midterm Review of the Implementation of the Sendai Framework 2015–2030 (MTR SF). In May 2023, the High-Level Meeting of the General Assembly on the MTR SF was held at the United Nations Headquarters in New York [2]. The guest editors are pleased to publish this special issue in the Journal of Disaster Research, which comprises six articles sharing the research advancements presented at the WBF2023. We hope that this special issue on the WBF2023 will contribute to the literature on disaster science and further advance disaster risk reduction.

Building a resilient society is key to preparing for disasters beyond the planned scale. To achieve this, it is necessary to create a clear common understanding of what “resilient” disaster management means and to consider concrete methods to accelerate its social implementation. However, few opportunities have occurred to have these discussions with diverse stakeholders. Therefore, a panel discussion was held to consider the type of cooperation required to build a resilient society. Each speaker provided information from various perspectives, including emergency information, disaster prevention education, and scientific knowledge on the mechanism of tsunamis, and their impact on ecosystems. Based on the above, the panel discussion confirmed the need for various elements such as infrastructure, information, rules, and social structure. In particular, it is necessary to develop consistency with existing safety standards for disaster prevention using ecosystems. It was suggested that, in addition to the practice of education, cooperation with the media, which keeps up-to-date information on a long-term basis, is indispensable for raising awareness of disaster prevention. This panel discussion emphasized that disaster reduction is a difficult field for companies to enter and commercialize, however, it was emphasized that it is indispensable worldwide.

In the areas affected by the 2011 Great East Japan Earthquake, storytelling has been widely practiced. In this study, we conducted a four-group comparison experiment to examine the learning effects of "TSUNAMI-REAL," a shorttime disaster storytelling program, by changing the duration (long/short) and the format (TSUNAMI-REAL/normal lecture) of the storytelling. The results showed that the following three points: in TSUNAMI-REAL, 1) the amount of information that can be conveyed and the change in the listener's emotions are slightly lower, 2) listeners can more easily feel the reality of the disaster, and 3) listeners can remember more contents that the storyteller considers important than in regular storytelling.

Abstract Evacuation is a critical life-saving action, especially in devastating natural hazards such as near-field tsunamis. However, the development of effective evacuation measures remains challenging to the extent that a successful example has been referred to as a ‘miracle’. Here we show that urban structures have the potential to reinforce attitudes towards evacuation and significantly influence the success of tsunami evacuation. Agent-based evacuation simulations revealed that a distinctive root-like urban structure formed in ria coasts reinforces positive evacuation attitudes by effectively gathering evacuation flows and leads to higher evacuation rates compared to typical grid-like urban structures, which can explain the regional differences in the number of casualties in the 2011 Tohoku tsunami. Although a grid-like structure reinforces negative attitudes under low evacuation tendencies, with leading evacuees, its dense feature helps to propagate positive attitudes and drastically improve evacuation tendencies. These findings pave the way for making successful evacuation inevitable through harmonised urban and evacuation plannings.

Abstract After a natural disaster, it is important to maintain the health of the victims, but after the Turkey-Syria earthquake, this information has not yet been provided. Tohoku University has compiled information on maintaining health care after the Great East Japan Earthquake of March 2011 into a booklet, which is available to the public. The purpose of this study is to investigate user satisfaction with this booklet. A total of 505 organizations participated in this study by completing questionnaires and evaluating the booklet. Quantitative responses were analyzed and coded by theme. Open-ended responses indicated that it was difficult for the general public to understand the data in the booklet. This study shows the need to keep in mind the ease of understanding for the general public when providing information on post-disaster care. We hope that this study will lead to better health care information for the victims of the Turkey-Syria earthquake.

This study tries to investigate the effects and usefulness of disaster memorial museums in the affected area by the 2011 Great East Japan Earthquake (GEJE): Iwate and Miyagi, compared with museums in other affected areas: Hyogo, Niigata, and Tokyo. We conducted an internet survey of the people (N=137) visiting the five disaster memorial museums. The five museums could be classified into four categories based on three axes. It is suggested that the two museums of GEJE would be more effective in improving visitors’ ability of disaster risk reduction and more intention to pass them on to others and less in learning response, recovery, and reconstruction, preparedness than those in other regions. Finally, three measures/factors could be proposed to utilize the museums of GEJE more effectively.

In this study, we conducted a questionnaire survey and analysis of the tsunami evacuation behavior associated with the Miyagi earthquake that occurred on March 20, 2021 in Ishinomaki City, Miyagi Prefecture. The results are summarized as follows ; 1)51.3% of evacuees by a car are "people who can convert to evacuation on foot" assuming the 2021 Miyagi earthquake. 2) It is suggested that while promoting evacuation on foot saves many lives, it may be increase that the amount of property damage of automobiles. 3) Measures to promote walking evacuation include reviewing evacuation drill methods and contents, building relationships that praise walking evacuation within the community of residents, and promoting community development that does not require the use of cars in everyday life.

The global effect of COVID-19 is no longer simply a public health issue; it is causing an economic crisis that has a significant impact on the job market and people's lives. The disease has led to 43% of businesses temporarily closing, and almost all these closures are due to COVID-19. Organizations that have temporarily suspended their activities have pointed mainly to a decline in demand and employee health issues as the reasons for closure. In emergency and disaster management, perception often helps shape personality and how people act in certain situations. This study aims to examine personal risk perception of COVID-19 from many viewpoints and whether it affects motivation with regard to improving personal preparedness. We collected data from three major Japanese cities through a questionnaire survey and analyzed the results of the survey through factor analysis and multiple regression analysis by using the Partial Least Square Structural Equation Modeling (PLS-SEM). The three study areas include (1) the most damaged regions from the 2011 Great East Japan earthquake and tsunami, (2) the capital city and surrounding areas of Tokyo, and (3) Kumamoto, which has recently experienced an earthquake. The findings show a correlation between the nature of the information received during COVID-19 and worriedness and the necessity for adequate information. The expected benefit of this study is to provide guidelines for the government or organizations to make a suitable emergency management plan based on pertinent factors for future pandemics.

This study aims to examine people’s perception of well-being during the COVID-19 pandemic in Japan and quantitatively clarify key factors towards realizing evidence-based policymaking. In March 2022, 400 participants responded to a survey conducted through Rakuten Insight. The authors applied an ordinal logistic regression (OLR), followed by principal component analysis (PCA), to create a new compound indicator (CI) to represent people’s perception of well-being during the pandemic in addition to ordinary least squares (OLS) regression with a forward-backward stepwise selection method, where the dependent variable is the principal component score of the first principal component (PC1), while the independent variables are the same as the abovementioned OLR. Consequently, while analyzing OLR, some independent variables showed statistical significance, while the CI provided an option to grasp people’s perception of well-being. Furthermore, family structure was statistically significant in all cases of OLR and OLS. Moreover, in terms of the standardized coefficients (beta) of OLS, the family structure had the greatest impact on the CI. Based on the study results, the authors advocate that the Japanese government should pay more attention to single-person households affected by the COVID-19 pandemic.

Abstract Historical data can determine how adolescents recover from difficult situations such as the Coronavirus disease 2019 (COVID-19) pandemic. This study analysed 3 years of data obtained from high-school students who had been affected by the 2011 Great East Japan Earthquake and consequently evidenced the importance of increasing resilience among affected adolescents. This involved identifying factors contributing to resilience through a model that assessed for each tsunami disaster. This model was determined by assessing the correlation between survivors’ resilience scores and their measured psychological and lifestyle scores. This approach showed that, in all tsunami damage models, resilience was most affected by the depressed emotions. Thus, our approach suggests that interventions for improving the depressed mood may improve resilience in adolescents during the COVID-19 pandemic.

Abstract On 15 January 2022 at 04:15 UTC, the Hunga Tonga-Hunga Ha’apai (HTHH) volcano in Tonga produced a massive eruption that triggered a transoceanic tsunami generated by the coupled ocean and atmospheric shock wave produced during the explosion. The tsunami first reached the coast of Tonga and eventually reached many coasts around the world. This volcano previously underwent a massive eruption in 1100 AD, and an eruption occurs approximately every 1000 years. The 2022 HTHH event provides an opportunity to study a major volcanically generated tsunami that caused substantial damage. In this study, we present a numerical simulation of a tsunami with a state-of-the-art numerical model based on a submarine explosion scenario. We constrain the geometry and magnitude of the explosion energy source based on analyses of pre- and post-event satellite images, which demonstrate that the explosion magnitude varied from 1 to 90 megatons of trinitrotoluene (Mt). Estimated submarine explosion geometries result in a suitable explosion magnitude of approximately 25 Mt, as determined with the waveform from the tide gauge in the time and frequency domains. The tsunami wave first reached the northwestern part of Tonga’s Tongatapu within 10 min, with a maximum runup height of approximately 15 m, and covered the whole of Tongatapu within 30 min. Finally, the numerical simulation provides deep insights into the physical volcanic explosion processes and improves our understanding and forecasting capabilities of frequent and catastrophic tsunamis caused by submarine volcanic explosions.

In order to clarify the difference in tsunami evacuation behavior in the same area, we analyzed the data from the questionnaire survey on evacuation behavior of Fukushima-oki earthquake that occurred in the early morning of November 22, 2016 and the Miyagi-oki earthquake that occurred in the evening of March 20, 2021. The results are as follows. 1) The evening earthquake hesitated to take immediate action in the dark and focused on grasping the situation, so the rate of evacuation was slightly lower than the early morning earthquake. 2) In the evening, due to the heavy traffic on the road, more traffic occurred than in the early morning earthquake. 3) Regardless of the time of occurrence, the experience of participating in the training was related to the implementation of evacuation, and in the evening earthquake, gender. It was confirmed that (being a man), but in the early morning earthquake, the work style (being a part-time job) was related to the presence or absence of evacuation.

This study assesses the movement behavior of people during the Great East Japan Earthquake that occurred on 11th March, 2011, in Iwate, Miyagi, and Fukushima prefectures. The study is based on a governmental survey conducted after the earthquake and reveals the movement of the population according to the water depth. Here, we investigated whether the routes were in the direction of the danger or not after the disaster and highlighted the proportion of people moving in each direction and their characteristics. The results obtained were as follows: 1) more than 30 % of the people moved in the direction of the danger at least once after the disaster, 2) those who were carried by others tended not to move in the direction of the danger, 3) governmental employees (e.g., city-hall workers, policemen, firemen...) tended to move in the direction of the danger, 4) those who were not at home at the time of disaster were more susceptible to move toward the direction of the danger, and 5) the signs indicating the flooded areas of historical tsunamis and evacuation directions may have helped to prevent their movements to the direction of danger.

This study investigates how to utilize Disaster Memorial Facilities in the affected area by the 2011 Great East Japan Earthquake to pass on the disaster effectively. We conducted an Internet survey among visitors and non-visitors to the affected area (N=1,775). The results can be summarized as follows. 1) Visitors who have never visited the affected area for learning purposes also visit Disaster Memorial Facilities. 2) Visitors expect to learn about disaster response, recovery, and reconstruction after the disaster, but these expectations have not been fully met. 3) The 46 facilities can be classified into four groups based on the visitor’s purpose and the effect on promoting disaster preparedness. Some facilities are effective in promoting disaster preparedness even though many of visitors are non-learning visitors.

<title>Abstract</title> Researchers believe that the impact of repeated trauma on mental health is incrementally more significant than the simple additive effect of one event. This study questioned whether this repetition only further worsens people's mental health. We found that they may report more positive changes than those who haven’t. Thus, we hypothesized that repeatedly experiencing difficult situations and suffering might increase post-traumatic growth (PTG). PTG can be defined as "positive psychological changes experienced due to coping with very difficult life situations," leading to positive outcomes and feelings of well-being. We found that those who experienced a disaster in the past were more depressed, anxious, and stressed than those who had never experienced a disaster and now experienced the COVID-19 pandemic. Additionally, past disaster experience led to a more psychological response to the COVID-19 pandemic, which, in turn, led to an increase PTG. Globally, we found that supportive social interactions, including those with family members, could develop PTG during the COVID-19 pandemic and achieve better well-being during the continuation of the pandemic in the future.

Field survey of bathymetry, sediment and bedrock of the narrow in Kesennuma Bay have been investigated. Numerical simulations of tsunami-induced sediment transport during the 2011 Tohoku tsunami were also improved by using the bedrock and sediment dataset. After the tsunami, depositions at the center of the narrows, erosions at the sides and the north area, and depositions at the south area were confirmed. By utlizing the bedrock data, the reproducibility of the field modeling was improved although the erosion of the narrows was limited to the bedrock distribution. It was found that the introduction of the bedrock is important to prevent underestimation of flow velocity and topographic changes. Furthermore, the simulations with simple consideration of erosion resistance due to the geology showed that the effect of erosion resistance was small and within the range of conventional modeling. The erosion speed in the narrows was characterized during the rising and the stationary period of the Shields parameter.
Are the Lessons Learned from the 2011 Great East Japan Earthquake and Tsunami Transmitted?:- A Trial of Evaluation for Tohoku University MOOC Participants -

This study aims to clarify how Japanese people understand lessons learned from the Great East Japan Earthquake and how understanding the lessons influence their disaster preparedness. We conducted a questionnaire survey of Tohoku University MOOC participants. The results are summarized as follows. 1) "Don't put all your faith in hazard maps" is the best well-known lesson. Respondents understand lessons regarding tsunami hazard itself and evacuation shelter less than regarding tsunami evacuation. 2) In the group of those who have not experienced any disasters, those who have visited affected areas by the Great East Japan Earthquake understand more lessons learned than those who have not yet, and understanding the lessons learned is a significant predictor of disaster preparedness.

 It is necessary to evaluate tsunami hazard maps created before the 2011 Great East Japan earthquake to mitigate human casualty in case of overestimated tsunami disaster. Servicing and utilizing condition of the hazard maps in Miyagi Prefecture at the time of the 2011 tsunami was investigated. Moreover, people's recognition of the hazard map and their evacuation behavior in areas outside the predicted tsunami hazard map was also considered. As a result of the analysis using the data of temporal response for tsunami, it is found that correlation between recognition of the hazard map and evacuation behavior is not significant. Nevertheless, correlation between recognition of hazard map and tsunami risk recognition is significant. In addition, problems regarding evacuation behavior in each study areas were also revealed. In Kesennuma City, disaster image fixation occurred as peoples were stick to the predicted tsunami inundation limit shown in the hazard map. In Ishinomaki City, conceiving of evacuation behavior for tsunami and evacuation behavior was not well connected. From these results, it is important to develop multi-scenario hazard map which considered uncertainties of external forces to improve understanding of hazard maps.

Complex disasters may occur as a result of a natural disaster combined with an industrial or a technological disaster. These are also called “natural-hazard triggered technological (natech) disasters.” Currently, there is increasing awareness of the hazards of these natech disasters. Natural disasters could trigger a technological disaster including oil spills and the release of hazardous and flammable materials and toxic chemicals, causing cascading events. The impact of the damage on public health and safety could be catastrophic, as it may result in massive loss of life, environmental destruction, and asset and property loss. Moreover, it could cause business disruptions and affect a country’s reputation. This paper describes a case study on the application of disaster risk reduction and management for natech disasters in Cilegon, Indonesia. We introduce the analysis of risk assessment conducted in Cilegon, the preparedness of the Cilegon City government, a contingency plan that has been developed, and the state of disaster preparedness in industrial zones. Natural and technological disaster risks as well as several emergency preparedness efforts are discussed and multiple stakeholders are identified. The paper serves as a foundation for future research to address natech disasters.

 Approximately 340,000 people's evacuation behaviours were simulated with a supercomputer for investigations of tsunami evacuation risks in a coastal urban city. The large-scale simulation that models individual detail movements clarified potential risks such as delays of evacuation due to congestions in evacuation routes and overcrowded situations at evacuation sites. Additionally, the simulation demonstrated that those potential risks could be reduced by an evacuation control based on tsunami inundation forecasts. Simulated results with different departure scenarios indicated that approximately 40 minutes lead time is available for evacuations without casualties in the study area. These results suggest that tsunami forecast that can be completed within the lead time can contribute to smoother evacuation behaviours.

 In this paper, we conducted a questionnaire survey for survivors affected by the Great East Japan Earthquake in Natori city, Miyagi prefecture. Thereby, we clarified the actual conditions of tsunami risk perception, disaster prevention literacy, preparedness for next earthquakes and tsunami of inhabitants who rebuilt in the area inundated by the tsunami. As a result, the following main results were obtained. 1) Compared with the inhabitants who relocated to inland, the inhabitants who rebuilt in the area inundated by the tsunami have lower tsunami risk perception. And the proportion of those who think that tsunami will come again while they are alive is high. 2) Many people think that they will not be affected themselves by tsunami even if they predict the return of tsunami. 3) There is a possibility that the disaster prevention literacy of the inhabitants who rebuilt in the area inundated by tsunami is lower than that of the inhabitants who relocated to inland. 4) The inhabitants who rebuilt in the area inundated by tsunami is higher for the proportion of those who implement the preparation for tsunami. On the one hand, for other preparations and the total number of the preparations, the inhabitants who relocated to inland is higher.

 Characteristics of tsunami oscillation in Tokyo, Sagami and Suruga Bays were investigated regarding the estimated Nankai-Trough megathrust earthquake models. In the cases where there is a large fault slip in the Nankai area, the oscillation of 76 minutes period was commonly excited in the three bays. In the cases with a large slip area in the Tokai or Tonankai area, the 68-minute component was excited only in Suruga and Tokyo Bays. The tsunami tended to be prolonged in the three-bay oscillation mode. The tsunami in the Keihin Canal in Tokyo Bay tended to be strengthened when the oscillation of the entire Tokyo bay include the components that are close to the characteristic period of the canal (30 min). In considering the continuity or amplification of tsunamis of canals in Tokyo bay, it is useful to focus on the macro-scale tsunami oscillation mode among the three neighboring bays.

The 2011 Great East Japan tsunami caused large scale devastated damage in both offshore and inland areas. There are many previous researches that were focusing on the relationship between tsunami characteristics and damage or loss such as human loss, building damage and fishing boat damage. Similarly, great damage and loss of aquaculture and marine ecosystem was also caused by the 2011 tsunami. However, relationship between the tsunami and their damage has not been studied. To understand such relationship, this study has mainly three components namely 1) Reproduction of the 2011 tsunami, 2) Damage investigation and 3) Developing fragility functions. The source models of the 2011 tsunami were verified and adjusted so that the tsunami characteristics were able to accurately reproduce in the target area. Damage ratios of the aquaculture raft and eelgrass were investigated using satellite images taken before and after the 2011 tsunami through visual inspection and binarization. The tsunami fragility functions were then developed based on the relationship between the simulated maximum flow velocity and the calculated damage ratio. It was found that the damage ratio of higher than 0.5 is equal to the maximum flow velocity of 0.8 m/s (aquaculture raft) and 1.0 m/s (eelgrass). Whereas, the damage ratio of higher than 0.9 is equal to the maximum flow velocity of 1.3 m/s (aquaculture raft) and 3.0 m/s (eelgrass). It was found in this study that the tsunami amplitude had no relationship with the damage ratio. In addition, the proposed fragility functions for the aquaculture raft are getting along well with the previously proposed damage criteria. The proposed fragility curves will be useful for marine product and environmental damage assessment but also suggestion for the zoning of aquaculture raft to mitigate impact from tsunamis in the future.

 Disaster Response drills are held actively in various places in Japan. But it is not clarify an effectiveness of participating the drills on actual disaster situation. In this research, we examined the relationship between tsunami evacuation drills and evacuation behavior at the 2016 Fukushima earthquake on 22nd November in Ishinomaki city, Miyagi prefecture based on questionnaire survey and analysis. The results were following. 1) People who participated in the tsunami evacuation drill have evacuated more than 15.2 % those who have not participated. 2) Although there is no difference in evacuation start time between them, people who have participated in the drill evacuated earlier about 3 minutes. 3) 56.7 % of participants could exert a drill experience, and 16.4 % of participants not able to exert the experience.

 It is necessary that the existence of tsunami monuments is recognized by residents in order to reduce casualties in the tsunami disaster. In this paper, we evaluated the characteristics of awareness for tsunami monuments by questionnaire survey in Rikuzentakata city. Consequently we drew the following four main conclusions: 1) Degree of recognition of the tsunami monuments is 35.0% in Rikuzentakata city, and degrees of recognition were different according to each region. 2) It was found that location and shape are more important than inscription of the tsunami monuments to be highly recognized. 3) Residents who recognize the inscription are less than 40% out of residents who recognize the existence of tsunami monuments. It indicates that it is difficult to transfer the memories and lessons of past tsunami disasters to next generations through the tsunami monuments. 4) It is difficult for children below elementary school age to know that tsunami monuments were made by past tsunami disasters. Additionally, it was clarified that younger residents have the thin relations with tsunami monuments. These knowledges indicate that some support for young generations is essential in order to transfer tsunami traditions through the tsunami monuments.

 Although the area has no human damage attacked by Fukushima earthquake tsunami on 22th November, 2016 in Japan, the event has different characteristics from recent tsunami. In this paper, we have conducted questionnaire survey on residents in inundation area at the 2011 Great East Japan Earthquake and tsunami in Ishinomaki City, Miyagi Prefecture to clarify tsunami evacuation behavior. The results are as follows. 1) At the rate of resident evacuated in the survey area was 41.2%. 2) Half of the evacuees by cars caused a delay in traffic jam at the multiple site in the city. 3) Residents who have high risk awareness of tsunami occurrence, experience of high damage in the 2011 disaster and participant of evacuation drill hold by the city evacuated the event more than not.

An integrated tsunami model consisting of models for simulating tsunami inundation, drifting objects and sediment transport, was newly developed to evaluate the effects of these multiple phenomena. A scenario of complex tsunami damage enlargement in a bay with bottleneck was revealed. The tsunami hazards in Kesennuma City, especially at the inner part of the bay such as Shishiori area, were enlarged by erosion in the bottleneck of the bay. The bathymetric change increased the drift distance of the drifting vessels. In addition, through the tsunami fragility functions based on dataset of actual damaged building and numerical results, it was evaluated that the 200 - 1,800 wooden buildings were washed away owing to sediment transport. Furthermore, it is found that the estimation accuracy of damage scale by the conventional fragility functions was suitable, although the estimated building damage near the sea and inland was under and overestimated, respectively.

 Estimation of human casualty due to tsunami provides us useful information for effective disaster prevention countermeasure. However, there is still no the method that is applicable to various areas because the estimation is strongly influenced by characteristics of the original data. The actual human casualty and building damage data caused by the 2011 Tohoku Tsunami was collected over the wide area and arranged by a fine spatial scale as small as district level. Using such data, we can avoid characteristics of the specific city that strongly influences the estimation results. The ratio of estimated exposure population and actual human casualty is defined as a damage characteristic coefficient which can be explained by the logarithmic normal distribution. The new human casualty estimation model includes the mentioned damage characteristic coefficient. The new model has border application and estimates the damage amount with a range of uncertain. The new method was applied to estimate the human casualty in two different coastal topography areas namely Kamaishi city and Sendai city in case of the 2011 tsunami and verified by comparing the estimated number of casualties with the actual number of casualties.

 This paper presents a new methodology for tsunami evacuation risk evaluation considering uncertain factors in evacuation analysis based on multi-scenario tsunami evacuation simulation. First, Uncertain factors in tsunami evacuation simulations and its well-defined parameters are organized. Then, the evaluation methodology is applied to an actual urban environment with the defined parameters. Based on the multi-scenario analysis, we found the uncertain factors can have huge effect on simulation results such as evacuation completion ratios. The new methodology can offer reliable evacuation risk evaluation by reflecting the effects of the unsertain factors to evaluation results.

 An assessment of tsunami hazard and risk on global scale is important as it can be non-structual measure to increase awareness of coastal residents against tsunami hazards in their locations. However, there are still less number of studies that were focusing on tsunami hazards across the ocean. Therefore, representative cases of tsunamigenic earthquakes were selected based on seismic records over the last 400 years. For each events, distribution of maximum wave amplitudes and arrival times were calculated using tsuanmi numerical analysis in the global scale. In addition, future tsunami hazard assessment was also performed based on the seismic gap. A necessity of assessing both historical and future tsunami hazards in the global scale is then represented in terms of hazard map comparing both scenarios in the global scale.

&nbsp;The Conical Fault Model that reproduces self-similar rupture growth and ununiformity of final slip distribution with a few fault parameters was developed. Using this model, the sea-bottom surface deformation due to the 2011 Off the Pacific Coast of Tohoku Earthquake and offshore tsunami waveform at the coasts of Iwate, Miyagi and Fukushima Prefectures was calculated and reproduction accuracy of observation data was evaluated. On the other hand, the same evaluation was conducted for a conventional fault model that assumes uniform slip in a rectangular fault plane. In order to explore the relationship between the number of unknown fault parameters and reproducing accuracy of tsunami waveform, single and multiple faults were considered in both model. As a result, the new model reproduced tsunami waveform with higher accuracy and with less parameter than the conventional fault model. Furthermore, moment rate function of the new model was similar to those that were obtained based on inversion for teleseismic and strong motion data. Thus, the Conical Fault Model is useful to reproduce tsunami waveform of earthquakes when observation data is limited.

 Our study is aimed to propose a strategic design using numerical tsunami analysis to design a coastal forest zone. In our first-level analysis focusing on hazard reduction, we inputted our expanded coastal forest plan along with actual topography data into a numerical analysis to estimate building damage caused by a tsunami in Iwanuma City. Our estimations showed that the effect of our coastal forest expansion strategy on the coastal regions was large compared to the inland effect, and caused the reduction of building damage, particularly in the Tamaura region. In our second-level analysis focusing on the reduction of human damage, we found that increasing the amount of coastal forest within a multipronged tsunami mitigation scheme could extend the evacuation distance for the Tamaura Elementary by over 100m. The numerical analysis-based design methodology presented in this study can be used to carry out this work in regions that are likely to be exposed to tsunamis in the future.

 Repeating a practical evacuation drills are important, and such a drill is often hold recently. But the effectiveness of repeating evacuation drills is not evaluated objectively. The purpose of this study is to demonstrate the effectiveness of repeating evacuation drills which were hold in Watari town every year from 2013. The three focuses of this demonstaration are residents' evacuation time, efficiency of checking students' safety and reflection after the drill. The results were the followings: 1) The rate of residents which can be evacuated from inundated area was increasing. 2) The efficiency of checking elementary and JHS students' safety was increasing. 3) The new problems for drill were found and the old ones were improved or decreased.

 In this paper, we considered the relationship between tsunami monuments and historical tsunami inundation areas, focusing on 176 tsunami monuments in the coastal area of Iwate prefecture. Furthermore, we also discussed the effectiveness of tsunami monuments in reducing human casualty in case of the 2011 Great East Japan earthquake and tsunami. Consequently, we drew the following four main conclsions. 1) About 75% of the tsunami monuments in the coastal area of Iwate prefecture were located outside of inundation area of the 2011 tsunami. The locations of these tsunami monuments can be target points for tsunami evacuation in the case of large tsunamis such as the 2011 event. 2) If the inundation area of the 1896 Meiji Sanriku tsunami was considered, some of the tsunami monuments based on the 1933 Showa Sanriku tsunami, which were located inside the inundation area of the 1896 tsunami and the 2011 tsunami, might not be damaged by the 2011 tsunami. 3) Based on the analysis of relationship between maximum height of tsunami and human casualty in each local district, human casualty against the maximum height where the tsunami monuments were located outside of the inundation area is smaller than that where the tsunami monuments were located inside the inundation area. 4) Since some of tsunami monuments with the function of education are located inside of historical tsunami inundation areas, this lead to increasing human casualty.

 Based on lesson learned from the 2011 Great East Japan tsunami, tsunami height is the most influential factor on fatality of people living in coastal area. This paper proposes effect of breakwaters on fatality ratio of people and investigate a reduction of fatality ratio due to the existence of breakwaters. For preliminary study, 24 fishery ports equipped with breakwaters were selected to study how breakwaters affect to loss of fatality ratio along Sanriku ria-coast from Taro to Ishinomaki. The port area behind breakwaters was considered to calculate fatality ratio from number of fatality divided by total number of people and then fatality ratio was linearly correlated with observed tsunami height. In order to estimate fatality ratio in case of ports without breakwaters, simulated tsunami height was calculated by TUNAMI modeling with nesting grids of 1350 m, 450 m, 150 m, and 50 m. For the overall image, breakwaters could reduce fatality ratio of people in the port area with a percentage of reduction approximately 30%. Considering the effect of breakwaters at each port, it was found that fatality ratio of ports equipped with breakwaters is less than those in case of ports without breakwaters for most of ports. In addition to these 24 ports, 18 additional ports equipped with breakwaters were conducted to additional study and compared with 24 ports having no breakwaters. For the overall image, the percentage of reduction became 1%, which is much lower than the reduction in the preliminary study. Focusing on each port, two third of them still provided the reduction of fatality ratio.

 Analysis of human casualty have been studied with data in city or town scale. However, analysis in these scales cannot capture the casualty characteristics that vary even by small administrative areas. This leads the difficulty of human casualty estimation for future tsunami disasters. In this paper, we conducted statistical analysis of human casualty in the 2011 Tohoku tsunami especially focusing on Ishinomaki City, where had the largest human casualty in this tsunami event, using the casualty data in fine scale as small as district level. The results show high correlation between tsunami inundation depth and fatality ratio and also building damage ratio in fine scale. Factors that might lead to large human casualty were considered based on the result. Statistical model explaining fatality ratio using tsunami inundation depth and building damage ratio were developed. These models show possibility of fatality estimation in future tsunamis under certain conditions.

 We estimated tsunami mitigation effects of coastal forest, multiple countermeasures, and its combination by tsunami numerical analysis and actual damage data in Iwanuma City. Our results demonstrated that coastal forest could delay the tsunami arrival time at around the Sendai-Tobu Road by a maximum of three minutes. Reduction of building damage probability and fatality ratio in all areas other than Yanome District can be confirmed. Furthermore, scenarios focused on a multiple defense system were also considered in our hazard assessment. As results, the current multiple defense system shows tsunami mitigation effect. Configurations and combinations of the multiple defense system could increase the mitigation effect. Tide embankment decreases inundation of tsunami, and hill decreases flow velocity of the rear. Multiple defense system utilizing these characteristics with the combination is effective for tsunami mitigation.

General disaster evacuation training for elementary and middle schools designate the assumption of disaster occurrences while in class time and participants are only students and teachers. However, in actual evacuation, disaster occurance is independent of time and multi stakeholder are involved. This paper is to explain a evacuation training method which all schools, residents and local government office participate in a fixed municipality. The results were the followings: 1) Middle school students and the higher class students of elementary schools played important roles that are coordinate younger student and safety confirmation themselves. 2) The time required for safety confirmation of schools related to student size without regard for types of evacuation. report and aggregate information. 3) Schools, resident organizations and the government office are gradually catching on mutual circumstances with this planning and training as a start.

In the case of tsunami evacuation, people to escape are not only existing residents and workers but also visitors such as tourists and business travelers in estimated tsunami inundation area. This paper aims to clear behavioral characteristic of visitor on tsunami evacuation and to discuss effects of evacuation guidance sign and verbal instruction with an experiment in the central area of Ishinomaki city. The results were the followings: 1) Tsunami evacuation spot as a destination point should be selected on the basis of simple route from starting point better than shortest distance. 2) Tsunami evacuation guidance sign does not always effectively navigate a visitor. 3) It is important that verbal instructions is not used "local spoken term" such as landmark name called in only the area, not official and standard name.

The real-time tsunami forecast using the database or real-time simulation was tried to develop before 2011 Tohoku earthquake. However, the method using a database and the real-time simulation are sub-ject to improvement of accuracy and large-scale calculation facilities respectively. After 2011 Tohoku earthquake, a new study proposed a real-time estimation of tsunami source by using the crustal move-ment and GPS tsunami observed data for tsunami forecast, which will provide us with the tsunami initial condition with higher accuracy in real time. Therefore we combine the database with a new study in real time to estimate a tsunami inundation in a short time even by PC computer. In this study, we compared this forecast with the tsunami inundation area caused by 2011 Tohoku earthquake. As a result, this method could provide information on inundation area for evacuation within 10 minutes after an earthquake occurrence.

In order to accurately predict evacuation behaviors caused by a tsunami, evacuation simulation taking into consideration vehicle-pedestrian interaction and detour routing to the shelters has been developed and applied to the case of Kesennuma City where detail information on the evacuation at the 2011 Tohoku earthquake and tsunami are available from fact-finding investigation by the Japanese MLIT and Kesennuma Municipal Government. The simulation well reproduces evacuation traffic flow as reported from MLIT and Kesennuma Municipal Government. The shortest path routes adopted in previous studies are unable to well reproduce the traffic flow, therefore we revised the method by changing potential value depending on the importance. The study demonstrates the existence of the effects of vehicle-pedestrian interaction. The area where influences were observed in the simulation is same as area where the risk of car-pedestrian interaction was mentioned by evacuees. The evacuee population in some shelters in the simulation well reproduces the trend of the real number of evacuees reported by the Kesennuma Municipal Government.

School buildings are important facilities due to their capacity as evacuation shelters. In 2013, Typhoon Haiyan and its storm surge damaged most schools in the affected area because they were one story structures built using weak material. Therefore, school buildings used as evacuation shelters did not function effectively. Thus, more studies on vulnerability of school buildings to coastal disasters in terms of damage and use as evacuation shelters are needed. A field survey was conducted from 26 May to 2 June 2014 to observe damage to school buildings in Tacloban, Palo and Tanauan. One-third of the schools were damaged by a combination of both typhoon winds and storm surge, and the rest by typhoon winds only. Detailed damage data on 166 school buildings in 39 school districts was directly obtained from Tananuan. The data for each building contain economic damage, building area and percentage damage to building structure, namely roofing, roof frame, ceiling, wall, window and door. Economic damage ratio is calculated as the ratio of loss to building area. The data was then overlaid on the storm surge inundation map created by field surveys and the distance of each building from the sea measured. Numerical simulations were applied to obtain the maximum storm surge flow depth and flow velocity, with wind speed derived from JMA data and a parametric hurricane model. The percentage of damage, distance from the sea and other disaster-related parameters were plotted in order to compare damage between the buildings inside and outside the storm surge inundation zone. Results show the damage ratio to walls is 0.3-1.0 in the storm surge inundation zone and decreases to about 0.5 or less for buildings outside the inundation zone. The average loss ratio is about 5,500 Philippine Peso (PhP) per m² due to the strong wind speed of 50-60 m/s.

We propose a quantitative evaluation method of overall tsunami risk that the entire facility group over a wide area holds. We considerably reduced the calculation cost for tsunami inundation depth by adopting the evaluation method using energy conservation law as compared with the evaluation method using nonlinear long wave equation. For financial institutions such as banks and insurance companies with contractors over a wide area and business companies with multiple their assets and facilities in various places, the proposed evaluation method in this study could be a useful approach to implement their risk-based management decisions for tsunami risk.

The 2011 Tohoku Earthquake which exceeds the maximum magnitude of historical earthquake records could not be predicted. Which means, in the probabilistic tsunami hazard assessment for the future prediction, it is necessary to apply a different concept from the existing scenario tsunami assessment based on the maximum magnitude of historical earthquake tsunami. As a new modeling method for scenario tsunami, we propose a characterized tsunami source model which indicates setting method of the area of tsunami source and slip distribution by the inter-plate earthquake.

We develop a tsunami simulator integrating a 3-D fluid simulation technology that runs on large-scale parallel computers using smoothed-particle hydrodynamics (SPH) method, together with a 2-D tsunami propagation simulation technique using a nonlinear shallow water wave model. We use the 2-D simulation to calculate tsunami propagation of scale of about 1000km from epicenter to near shore. The 3-D SPH method can be used to calculate the force that a tsunami can exert on a building, and to simulate flooding patterns in urban area of at most km scale. By applying the processing power of computers to the technologies resulting from this research, we seek to contribute to improved disaster preparedness and disaster mitigation through a better understanding of tsunami's mechanisms.

We analyzed the process decay of tsunami waveform based on the observed one due to the 2011 Tohoku-Oki earthquake. The observed waveforms at 31 stations along the Pacific coast of Japan were divided into four domains with periods and were evaluated respectively for each physical parameter such as the arrival time, the amplification time of tsunami of the later phase, the maximum tsunami amplitude of the later phase and the decay time. We found out that the decay time of the long period component is generally longer than the short period, but in some cases the time of short period component becomes longer than the others, which may be affected by radiation wave due to large scale bathymetric structure such as the Emperor seamount.

In case of tsunami evacuation, on foot is principle in Japan based on several lessons from the past. However, there is a tremendous need for tsunami evacuation by a car in coastal area where no high ground including high building is found. This paper aims to design a new tsunami evacuation plan with combination of walking and cars in Watari town. The major reasons of car evacuation need is no high safe zone and far out of inundation area in coast. As a result of primary simulation, it is found that 46.0 % people in tsunami inundation area of the 2011 Great East Japan Earthquake disaster cannot escape from tsunami on foot. We propose a flowchart which select tsunami evacuation transportations (walk or car) and suggest directions (horizontal or vertical) for each district, and suggest an evacuation plan combination of walking and cars.

We performed a stochastic evaluation of tsunami inundation by using results of stochastic tsunami hazard assessment at the Soma port in the Tohoku coastal area. Eleven fault zones along the Japan trench were selected as earthquake faults generating tsunamis. The results show that estimated inundation area of return period about 1200 years had good agreement with that in the 2011 Tohoku earthquake. In addition, we evaluated quantitatively tsunami risk for four types of building; a reinforced concrete, a steel, a brick and a wood at the Soma port by combining the results of inundation assessment and tsunami fragility assessment. The results of quantitative estimating risk would reflect properly vulnerability of the buildings, that the wood building has high risk and the reinforced concrete building has low risk.

Before the occurrence of the 2011 Tohoku earthquake, a tsunami inundation forecast system and a GPS buoy were installed in Tohoku. The huge tsunami generated by the 2011 Tohoku earthquake was observed with the GPS buoy, and the data were used to revise the tsunami warning. However, the tsunami inundation forecast system was not able to help in the evacuation. The tsunami inundation forecast system was a system that displayed an inundation forecast map corresponding to the tsunami height observed in the GPS buoy in real-time. We thought that the damage would have been mitigated if the information from these systems were used for evacuation. Especially, the tsunami reached Sendai around 36 minutes after the tsunami was observed in the Kesennuma-oki GPS buoy. We thought that damage might have been mitigated if the information was conveyed during these 36 minutes. The 2011 Tohoku earthquake was generated in Tohoku where such a system was constructed. Therefore we thought that we must report the process of constructing these systems, the effects of the systems and the problems encountered.

天体が海洋に衝突した場合,巨大津波の発生が懸念される.本稿では,太平洋への隕石落下頻度を検討し,数値計算に基づき日本への衝突津波リスク評価を予察的に行った.その結果,他の災害に比べれば衝突津波の発生頻度は低いものの,現実的な災害リスクとして認識する必要があることがわかった.衝突津波のリスクは確率的に評価が可能なため,現在の量的津波予報のような形でデータベース化することが可能であると考えられる.将来的には,衝突から津波伝播・遡上までの一連の過程の計算を連続的に行うことが望ましい.数値計算技術の高度化が進めば,火星の古海洋の存在可能性の検討など,惑星科学分野での応用範囲も広いと考えられる.

Activities to collect disaster archives are quite important for disaster prevention education and remaining in memories. There are many projects aiming to collect records and evidences concerning to the Great East Japan Earthquake. Hereafter, this sturdy will be used as a basic material to achieve effective activities to collect records. Also, the current issues and spatial tendency of collecting activities would make clear. Using a database of KahokuSinpo, which is a local newspaper in Tohoku region, and retrieval service of Internet, 54 projects are picked up. They are divided to each 5 attributes: Contents, Continuity, Accessibility, Spatial distribution, Main parts of an activity. As a result, activities tend to focus on serious affected area, especially coastal area.

The purpose of this research is to develop a Tsunami Trace Database by collecting historical materials as well as documents concerning tsunamis which had hit Japan and, of which the reliability of tsunami run-up and related data is taken into account. Based on acquisition and surveying of references, tsunami trace data over past 400 years of Japan has collected into a database, and reliability of each trace data was evaluated according to categorization of Japan Society of Civil Engineers (2002). As a result, trace data can now be searched and filtered with reliability levels accordingly whilst utilizing it for verification of tsunami numerical analysis and estimation of tsunami sources. By analyzing this database, we have quantitatively revealed the fact that the amount of reliable data tends to diminish as it goes older.

In order to evaluate and forecast the decay process of far-field tsunamis, we have constructed a time-dependent decay model of MRMS tsunami amplitudes. This model is based on the decay features of near- and far-field earthquake tsunamis around Japan and on the assumption that the propagation of tsunami energy is expressed by convolution operations with three effects (source, path, and site effects) and some parameters. Computed examples show that with suitable parameters, this model has the potential to duplicate various real MRMS tsunami waveforms. Through this study, we successfully mitigated issues related to the timely cancellation of tsunami warnings; the problem we are still facing on the issue is to determine parameters and functions of three effects for the proposed decay model of MRMS tsunami amplitudes.

We propose the system to estimate the tsunami inundation in real time by collecting seismic and tsunami information and selecting suitable cases from all in the database, in which we assume possible faults model as scenario. In addition, the system includes the process to re-select suitable one by referring the tsunami observed data by GPS buoy. Some checkpoints that compared the height of the tsunami were determined for re-select. We propose a database for Kamaishi city of Sanriku Coast. And the 1896 Meiji Sanriku tsunami is used to discuss its accuracy of the tsunami heights and inundation area in each process for real time. As a result, we obtained a good accuracy of the result by using the system at the target area before tsunami arrival at the coast.

An earthquake of Mw 8.8 struck off the coast of central Chile on Feb. 27, 2010. A tsunami due to the earthquake propagated on the Pacific Ocean and attacked Japan on the next day. JMA issued a major tsunami warning for many coastal regions, however severe damage occurred in many ports especially for fishery. To understand the tsunami disaster, the filed investigation was carried out to record tsunami heights such as run-up heights and inundated heights along the comprehensive coastal region. In cooperation with many institutes, eyewitnesses interview, measurement of tsunami trace and analysis of tide records were conducted. Then the tsunami height distribution from Hokkaido to Okinawa is reported here. The tsunami was higher in the northern part of Japan and it exceeded 2 meters in the Tohoku district especially.

In order to estimate human loss caused by tsunamis, we proposed the method in consideration of resident's evacuation process that affected human behaviors and loss greatly. The process can be divided into three steps after earthquake, which could be modeled in this study. Factors affecting the evacuation can be statically clarified through the questionnaire survey of the evacuation process. And we evaluated the effective method and proposed the developed human loss evaluation method considering a local evacuation characteristic. Finally we applied it and carried out the evaluation of human loss in the target area

The aim of this study is to develop the practical numerical analysis model of tsunami to reproduce run-up soliton fission waves in the river. We verify accuracy and the computing time about the developed model by using the large-scale flume experiment. It has been understood that scheme of advective term and evaluation of space grid size have an effect on numerical result. We study the evaluation of space grid size and the computing time necessary for the calculation of the run-up tsunami with a soliton fission waves in the river. In this study, numerical algorithm of the soliton fission waves proposed by Shigihara and Fujima(2007) is very useful to calculate practically.

This study calculated the numerical simulation of Tsunami on Tokachi river with a soliton fission waves and examined the spatial resolution whichi is necessary for it. The soliton fission waves were recorded on video in Tokachi river at 2003 Tokachi-oki earthquake. We analyzed this video and obtained the continuous location information of soliton fission waves. The numerical simulation of Tsunami run-up using nonlinear dispersive wave equations model was able to reproduce the soliton fission waves. It is necessary to use the space grid size of 1/20 or less of the wavelength of soliton fission waves to calculate the amplification of the wave height by soliton fission.

In order to evaluate the decay process of far-field tsunamis, we have revised the definition of tsunami coda and related measures - moving root mean squared amplitude (MRMS amplitude), and non-dimensional tsunami amplitude (NDA) - in this paper. We applied these measures to the tsunami waveform data of 2006 and 2007 Kuril Island earthquake tsunamis observed by tidal stations located in Japan. Analytical results of tsunami coda of these events indicate that decay time constants obtained at tidal stations along the Pacific coast of Japan have only small differences. Further we confirmed that the NDA seldom exceed three times of MRMS amplitude. Then we show the possible application of utilizing these characteristics of tsunami decay process to realize appropriate cancelation of tsunami warnings.

The map showing Tsunami risk on geographic information is very important to let the people become aware of it as well as to promote the tsunami disaster countermeasure. The evaluation of risk given by the probability of occurrence and damage is during discussion. In this paper, we focus on damage evaluation of human loss through reviewing previous studies and proposing a new method to estimate the tsunami casualty by using fragility function and evacuation. Then we compare the results of evaluated casualty by using them to know their differences and applicability at city of Higashi Matsushima in Japan.

The quantitative tsunami forecasting system by JMA is in operation on the data base, in which the initial condition of tsunamis are assumed with less consideration of the earthquakes property in the region and with uncertainty. Since the initial condition for a tsunami simulation each local area is the most important to ensure the accuracy, the present study evaluates its effects on the tsunami heights in the data base. As a result, it is concluded that we should carefully select a strike, a dip angle, width and length by considering the characteristic of the focal mechanism, and especially that the influence of the dip angle affecting on the tsunami height is large.

Tsunami hazard assessment along the coast of Pakistan was carried out based on modeling of the 1945 Makran tsunami. We first modeled the 1945 Makran tsunami, which is the largest recorded tsunami in Pakistan, to examine its hydrodynamic feature. As a result, we found that the arrival time of maximum tsunami wave at Pakistan coast is prone to be late because tsunami waves are trapped and duplicated on continental shelf with a gentle slope. We further simulated potential tsunami hazard in Pakistan coast developing the scenarios based on historic earthquakes. The results showed that 5 -10 m tsunami would strike Ormara and Gwadar city, which are populated areas in Pakistan coast.

As the first step toward forecasting the decay process of far-field tsunamis, we have introduced the concept of using "tsunami envelopes" and "tsunami codas" as measures in this paper. We applied these measures to the tsunami waveform data of the 2006 Kuril Island earthquake tsunami observed using tide gauges located in Japan. Analytical results indicate that the tsunami coda envelopes decayed exponentially with time and that the fluctuation in the nondimensional wave amplitude was interpreted by the Rayleigh distribution. Further, we found that these characteristics were commonly observed in the region facing the Pacific Ocean. Thus, the two measures can be used to reveal the characteristics of the tsunami decay process, and applying them to tsunami waveforms in realtime might realize appropriate cancelation of tsunami warnings.

Mesh division of geographic model effects on results of run-up tsunami simulation. Recently, approximate accuracy ofgeographic models increase with using LIDAR (airborne laser). And run-up tsunami simulation using mesh of severalmeters came to be done. In this study, we study effects of mesh division on inundation area of run-up tsunami simulation.To exclude the effects of various conditions of the tsunami simulation, we designed the simplified probability calculationmodel. The calculation model determines the reaching probability of tsunami inundation area. As a result, the tendencythat inundation area of run-up tsunami simulation decreases as mesh size decrease was theoretically confirmed.

Tsunami can yield extensive topographic change, which causes secondary damages such as collapse of coastal structures.Therefore, it is important to analyze the topographic change due to the tsunami. In this study, we investigated spatialvariation of sedimentation and erosion due to the 2004 Indian Ocean tsunami at the Kirinda port, Sri Lanka by using thebathymetric data before (Nov, 2004) and after (Feb, 2005) the tsunami. We also conducted numerical analysis of tsunamipropagation and sediment transport. The results show that the tsunami caused approximately 5m erosion or deposition, and the shoreline was moved approx. 100m toward the offshore. Morever, backwash that was redirected by coastal structuresplayed a main role of significant erosion around the wave breaker.

We discuss the characteristics of the later-phase tsunamis accompanied with earthquakes along the Kuril trench, based on the numerical modeling of trans-oceanic tsunamis and the analysis of observed tsunami waveforms. The model results suggest that the later-phase tsunami is caused by edge waves or scattering waves from the seamounts, depending on the tsunami source location; tsunami energy radiated from south of 46° N can result edge waves andnorth of 46° N to 49°N can be scattering waves. Also, we found that analyzing the time evolution of Fourier spectra of observed tsunami waveforms can identify the cause of later-phase tsunamis and can be used to decide the timing of tsunami warning cancellation after it's issued.

In this study, we investigated the sediment transport due to the 2004 Indian ocean tsunami along the natural coast at Hambantota, Sri-lanka. Bathymetry and topography surveys before and after the tsunami were conducted and the results showed significant erosion by the tsunami, especially around the places where shoreline discontinuations were observed. We conducted a numerical simulation of tsunami propagation as well as the bathymetry change induced by the tsunami. Furthermore, we also estimated the bathymetry change due to the usual sea waves at the coast. Our numerical results suggested that the tsunami has strong bottom shear stress at specific landform such as a river mouth and a cape. We also found that the sediment erosion and accumulation due to the tsunami had been mitigated by usual sea waves after the tsunami.

Many evacuation simulation models have been developed. However, all the models exogenously set the rate of evacuation and the evacuation route which are inherently determined by residents. With the exogenous settings, these models can not follow the change in the residents' behavior according to changes in policies. Therefore, it is necessary to model residents who evacuate based on their individual rationality. And now, it is known in particular that residents will not evacuate by some psychological factors (e.g. cognitive dissonance). This paper, focusing on cognitive dissonance as psychological factors, constructs an evacuation model incorporating individual rationality and cognitive dissonance. As a result, we show the effects of cognitive dissonance on the residents' evacuation.

Sediment transport by tsunamis causes serious human injury and damage to buildings, coastal topography, and marine ecosystems. To understand processes of sediment transport by tsunamis, experimental and numerical studies as well as field investigations are important. In this study, we summarize experimental and numerical models for transport of sandy sediments or a large block, and then discuss their limitations and possible improvements. Although some problems and difficulties remain, these models generally are able to reproduce experimental results, and they can be adapted to the modeling of sediment transport by real-scale tsunami events. When these models have been improved to handle mixed grain sizes and multiple blocks, it will be possible to estimate hydraulic properties (hydraulic force, current velocity, and inundation area) of historical and prehistoric tsunamis more precisely by constraining the models with information on existing tsunami deposits and boulders. Moreover, sediment transport models are useful for estimating the spatial distribution of sediments eroded and redeposited by tsunamis ; thus, such models will be helpful in the selection of drilling sites for core samples in investigations of historical and prehistoric tsunami deposits.

Focusing on the scattering of tsuanmi energy by the seamounts, this study aims to discuss the effect of Emperor seamounts on the tsunami propagation of the 2006 Kuril Island tsunami, using a finite difference method. The model results suggest that the contribution of Emperor seamounts on the maximum tsunami energy along the Pacific coast of Japan is as much as 50 % or more. Also, the spectral analysis of the observed tsunami records in Japan indicates that the scattering waves from Kinmei seamount dominate the wave components of 8-20 minutes in its wave period, which is consistent with the theory of Longuet-Higgins (1967).

Sometimes tsunami transports large boulders (tsunami boulders). The movement of tsunami boulders could have directly related to the hydraulic force of tsunami. Our field observations clarified that long axes of boulders at Pakarang Cape, Thailand, which had been transported by the 2004 Indian Ocean tsunami, were likely to be vertical against the tsunami flow direction. Moreover, our hydraulic experiment revealed that boulder movement is affected by their initial long axes orientations, suggesting that shapes and long axes orientations of boulders must be considered in the numerical simulation.

In this study, run-up tsunami simulation with high-resolution topographic model is applied for design of tsunami countermeasure such as sea wall and breakwater in the case of coastal area in Sanriku. The topographic model of 10m grid DEM (Digital Elevation Model) is made by LiDAR (Light Detection and Ranging) data. Theresolution of the altitude of LiDAR data is 15 cm. The behaviors of tsunami on the land with three plans of the countermeasure in the coast are carried out using tsunami simulation and compared. The effect to reduce the inundation area and damage, and the coast to construct them for each plan are discussed.

As tsunami information, not only issuing but also canceling is important for emergency management. Although tsunami database and real time observation data recorded at stations are available, those are not used for canceling to estimate the tsunami attenuation. This study evaluate the attenuation for 6 hours by using the tsunami database in Sanriku coast with the 394 faults models assumed. The index of the tsunami attenuation for 6 hours is proposed and estimated along the coast and sea regions, which can be used for canceling of tsunami warning after the tsunami wave heights are predicted.

We investigated the damage of mangroves by the 2004 Indian Ocean tsunami at Banda Aceh, Indonesia. We clarified that no mangroves could have survived in the west of Banda Aceh affected by more than 10m height of tsunami, although more than 50% of mangroves with 20-25cm stem diameter could have survived in the east of Banda Aceh affected by 5-7m height of tsunami. We simulated the 2004 Indian Ocean tsunami to investigate the impact on mangroves. Based on our field observation and numerical simulation, we estimated the destruction limit of mangroves using the relationship between the stem diameter and computed-tsunami bending moment. Furthermore, we evaluated the potential mitigating effect of mangroves at Banda Aceh using the numerical model with the destruction limit considered.

The destruction of storage of flammable materials by the hydrodynamic force of tsunami may result spread of large fires, flammable materials such as spilled oiland ignited material advected and diffused by the tsunami current in a harbor oron inundation land. To prevent damage from spreading in tsunamis and oil spills and functional decline in harbors, we carried out numerical simulation for oil spreading in the 1964 Niigata Earthquake Tsunami, in which the initial conditionsof land, water level, and oil are carefully given by considering the fault motion, liquefaction, and storage of oil. We proposed some conventional method to estimate each initial condition in the tsunami simulation.

The Japanese Islands are at a high risk of earthquake and tsunami disasters, because of concentrated population and industries in the coastal areas facing troughs and trenches along active plate convergent boundaries. We are able to learn much about past earthquakes and tsunamis from the geological records, including tsunami deposits and turbidites, and to make use of such information for disaster prevention. Evaluation of the physical properties of past earthquakes and tsunamis from geological records, such as their size and recurrence intervals, would be useful for evaluating the risk of future earthquake and tsunami disasters. Collaboration of scientists and engineers is needed to better understand past events and predict future events. This new attempt will solve the existing problems in the various study fields, e.g. geology and tsunami engineering. Better understanding of the risk of natural disasters in our milieu through these collaborative efforts will prevent future disasters.

It is rather difficult to reconstruct and understand the details of past tsunami events and behaviors because of limited information. Not only historical documents but also traces of tsunamis accumulated in the sediment can contribute to solving this difficulty. Although the documentation contains useful and valuable information to understand historical tsunami events, these descriptions of tsunami behavior are limited and there are many uncertainties involved. Thus, scientific evaluations of these data using the results from sedimentological study and numerical simulation with hydraulic models are required. In particular, since tsunami wave current and hydraulic force could be recorded in tsunami deposits, this information can be used for developing and calibrating the models. Study of sandy tsunami deposits is important to prepare for future tsunami events, because it is possible to understand the hydraulic properties of past tsunami events using sandy tsunami deposits. Not only the sandy particles but also the boulders transported by tsunamis are useful to understand past tsunami events. In this study, we introduce the numerical analyses of boulder transport by the 1771 Meiwa tsunami at Ishigaki Island, Japan.

The Tsunami generated by the Sumatra earthquake on December 26, 2004 affected many countries around the Indian Ocean and Thailand also suffered severely from this event, i.e. 6 provinces along the Andaman coastline. More than 8,000 people perished or went missing, 4,500 houses were totally destroyed, and economic losses were estimated at more than 14 billion baht. Since it bore the brunt of the tidal wave at its peak, Phang Nga experienced the largest number of fatalities or missing (more than 65%) as well as property damage (about 50%). The Government was prominent in several short- and long-term measures following the disaster management cycle, including the development of a tsunami resilient community. This paper discusses several measures implemented by the government, private sectors, and international organizations.

In the last two years, the tsunami phenomenon has become a very serious issue in Indonesia. The 2004 Sumatra tsunami caused 130,000 casualties with another 37,000 missing, presumed dead, and financial loss suffered reached $4.3 billion. A tsunami struck the Pangandaran area again, West Java Province, on July 17, 2006, which caused 668 casualties with another 45 missing and financial loss reaching $44.7 million. The damage to these infrastructures and lives clearly shows that disaster mitigation and disaster countermeasure efforts are still not running well. This is becoming the background to the urgent need for integrated tsunami disaster mitigation to build a well-prepared coastal disaster community in the near future.

The Indian ocean tsunami on 26 December 2004 was the biggest natural disaster in the history of Sri Lanka. Unlike many other countries affected by this tsunami, the damage in Sri Lanka was so widespread that about two thirds of the coastline from the northern Jaffna peninsula, along the eastern coast down to the southern tip of Dondra Head, as well as the relatively sheltered southwestern and western coasts, were subjected to inundation. More than 35,000 people died, 100,000 houses were damaged and 500,000 people were displaced, while the severe damage caused to infrastructure and environment exceeded US $ 900 million. It has been estimated that 3 to 5 years will be needed to complete the rehabilitation and reconstruction task at a cost of nearly US $ 2.2 billion. The recovery program has made some significant progress in certain areas and actions have also been initiated to improve the disaster mitigation capability in the country. This paper reviews the issues, problems associated with and progress of the recovery process as well as the work carried out to mitigate potential future disasters in Sri Lanka.

The 2004 Sumatra earthquake, occurred at 00: 58: 53 UTC on December 26, 2004, followed by the Indian oceanic tsunami was the largest earthquake in magnitude of M 9.0 in the world since the 1960 Chilean earthquake. The epicenter was located west off Sumatra Island, but the aftershocks extended through Nicobar to Andaman Islands; the total length is more than 1, 000 km. The number of casualties, death and missing together, is the largest in Indonesia (220, 000), followed by Sri Lanka (35, 000), India (16, 000) and Thailand (8, 300). About 300 fatalities are reported from Somalia, east coast of Africa. In total, nearly 300, 000 lives were lost by the tsunami. The information on the media and the result from the field investigation are introduced in the new disaster's point of view. The frame work to mitigate the tsunami disaster in the future is discussed in the paper.

The purpose of the present study is to develop and improve the simulation model of tsunami attack evacuation by including the experience, recognition, and knowledge of the people in each area affected by tsunamis. Firstly, we carried out two field surveys to clarify various factors that influence selection of evacuation routes for making a synthetic judgment model. We determined regional knowledge, altitude, road information, road signs, following process, and functions on the route to be major factors in the route selection. A comparison with results of a field survey in the case of a tsunami evacuation drill at the coastal village in Sendai city shows that with the improved model, we obtained more than 80% agreement on selection of evacuation routes and time to the safety area. Secondly, we designed a questionnaire to be distributed at the time of the drill, which provided us with information to determine route selection process, parameters and initial conditions of the evacuations. Furthermore, the improved model, including means of evacuation, such as by foot or in vehicles, is developed and applied to this area. In the case assuming that all residents evacuate at the almost same time in the night, it is suggested that most traffic congestion occurs on the major roads, which long time it takes people to complete the evacuation.

The paper introduces the activity for disaster mitigation of tsunami in Pacific ocean after the 1960 Chilean tsunami, which should be lessons to improve the research and public work for the mitigation in Japan. The Japan Meteorological Agency (JMA) failed to issue an effective tsunami warning for the tsunamis of the 1960 Chile Earthquake, being aware that international cooperation is essential. Through the experience of the 1960 tsunami, the two international cooperation organizations; ICG/ITSU and PTWC were started to establish the far-field tsunami warning system in the Pacific ocean. JMA also exchanges of tidal data with the United States of America and other states, monitoring the data of foreign eighteen stations in this area. DART, TIME in US, and Pacific museum are introduced for the early time warning system with high accuracy, making hazards maps to increase people awareness and evacuation system, and public education by providing documentation, exhibition, workshops, and lectures.

Tsunami height survey was conducted immediately after the 2003 Tokachi-oki earthquake. Results of the survey show that the largest tsunami height was 4 m to the east of Cape Erimo, around Bansei-onsen, and locally at Mabiro. The results also show that the tsunami height distribution of the 2003 Tokachi-oki earthquake is clearly different from that of the 1952 Tokachi-oki earthquake, suggesting the different source areas of the 1952 and 2003 Tokachioki earthquakes. Numerical simulation of tsunami is carried out using the slip distribution estimated by Yamanaka and Kikuchi (2003). The overall pattern of the observed tsunami height distribution along the coast is explained by the computed ones although the observed tsunami heights are slightly smaller. Large later phase observed at the tide gauge in Urakawa is the edge wave propagating from Cape Erimo along the west coast of the Hidaka area.

The purpose of this paper is an investigation of how to collect and use heavy rainfall disaster information by local governments. Questionnaire data were gathered from 230 municipalities within Iwate, Miyagi, Fukushima, Gifu, and Mie prefectures. They were struck by typhoon No.0206 in July 2002. 32 municipalities issued evacuation counsel for disaster. A half of it answered that the decisive factor of evacuation counsel was occurrence of damage. The result indicated that it was difficult to issue evacuation counsel in advance of damage. Respondenfs ratios of rainfall information received on real time were as follows: The rainfall data by Meteorological Agency (JMA) was 92 percent, the rainfall and water revel data by Ministry of Land, Infrastructure and Transportation (MLIT) was 72 percent, the rainfall and water revel data by prefecture was 78 percent Respondent's ratios of actually used information were as follows: The data of JMA was 74 percent, the data of MLIT was 38 percent, the data of prefecture was 51 percent It is necessary that the information of JMA and other information is unified. 58 percent municipalities had own raingauge on their office and 87 percent of raingauge data were used in this event. Self-administrated raingauge was relied. Flood hazard maps were made in 10 percent of municipalities. But municipalities of actually used hazard map in this event were a half of those. It is important that practicality of hazard map was verified.

Tsunami has caused heavy damage to the coastal areas in Japan where the activitive countermeasure have been carried out to reduce the possibility of disaster. Tsunami warnings that provide with the arrival time and tsunami heights before the attack was started in 1952 and recently improved incorporating a database using computer simulation, in which the initial of a tsunami is estimated from only just seismic information. Combined numerical simulation together with observation in real time is proposed to improve estimation of the initial tsunami conditions. Simulation used to evaluate the damage caused by tsunami such as casualties, destroyed houses, and so on has been developed with the GIS data and a model of human behavior for evacuation. Study on historical tsunami using the sedimentrological approach is introduced to understand the detailed behavior of recent and historical events on land.

The paper aims to report the activity of Papua New Guinea and Region Tsunami Conference (PARTIC) held one year after the enormous disaster due to earthquake and tsunami of 17 July 1998,consisting of three components; Public Awareness (PA), Tsunami Science (TS), and Disaster Management (DM). In PA, the expert team was drawn together and sent into the field to talk with survivors with the object of (a) giving at first hand the very latest findings of the scientific community to the survivors and (b) demonstrating that there is a clear consensus that the tsunami was a natural event triggered by an earthquake, and not the mischievous work of miscreants or a man-made power. The objective of TS sessions were (a) to bring together some of the scientists who are currently researching into the cause of the tsunami and (b) to inform PNG-based geo-scientists about tsunami science in general and about the Aitape tsunami in particular. In DM, representatives of the affected villages, disaster management officials from the central and local governments and various experts from NGOs and other organizations reported their findings, reviewed the prevention, response and relief activities, and discussed better ways to prepare for any future tsunamis expected to arrive on the coasts of PNG.

Based on data compiled during the period 1600-1999,105 tsunami have occurred in Indonesia. Ninety-five events (90%) of them were caused by earthquakes in a shallow region at subduction and plate boundaries, 9 (8%) by volcanic eruption, and one (1%) by a landslide. To clarify the regional characteristics of tsunami, we defined 6 zones ; West and East Sunda, Banda, Makassar, Molucca and Irian Jaya, and made the histograms of earthquakes and tsunami by region by decade from 1600 to 1999. Seismic activities were found in East Sunda, Banda and Makassar are high and tsunami activities in West Sunda, Banda, and Molucca. An interval of about 100 years was found for high earthquake and tsunami activities in the period 1800-1999. The percentages of earthquakes accompanied by tsunami to all earthquakes in Banda and Molucca exceed 50%. In terms of human loss due to tsunami, West Sunda is the worst zone because of the devastating damage done by the 1883 Karakatau volcanic eruption. The tsunami potentials in Banda and Molucca in terms of both frequency and damage are very high. Tsunami activity in Banda since 1960 has been remarkably high.

Heavy rain that began to fall from the beginning of August 26, 1998 wasespecially intense in the boundary region of Fukushima and Tochigi Prefectures. The total rainfall in six days reached more than 1200mm. This paper deals with the runoff analysis in the Abukuma River basin for this rain. The model based on the channel network with the mesh size of 500m and the kinematic wave approximation for the dircct runoff component was applied. The comparison between analysis and observation in the discharge gives the runoff rate of 0.73 which is about twice for the usual floods in the basin. The long duration of the previous rain is supposed to affect the high efficiency of the runoff.

The models and techniques for the numerical simulations of generation and propagation of tsunamis are reviewed, and future problems are summarized. First, several kinds of geophysical phenomena such as landslide, volcano and asteroid impact causing the generation of tsunami are discussed. Second, two layer model and Marker and Cell (MAC) method used to simulate the generation and propagation of specific tsunamis are explained. Finally, we discuss the problem of numerical errors in a tsunami simulation which is crucial to obtain stable and accurate results.

Interview, questionnaire and field investigation are carried out to clarify technical and operational problems on Tsunami Detection System recently installed at tsunami prone areas in Japan. Although technical problems of observing unusual sea level change due to coastal phenomena including tsunamis have been almost solved, a criteria to detect tsunami and a transmission system of tsunami information to local people are still not established, causing confusions in issuing tsunami warning and advisory instructions. The RTNS(Regional Tsunami Network System)interchanging information among each area is proposed through utilizing observations such as ultr asonic/ pressure type sensors and buoy-type gauges, which solves the problem in insufficient time to transfer information before a tsunami attack because most of tsunami gauge stations are located at fishery port near a residential area. For efficient interchange of information, the stations in the RTNS should be selected by referring travel time estimated by numerical simulations and a wave amplification at each area around stations should be known.

Possibility of quantitative forecasting of local tsunamis sufficiently before their arrivals, by use of a super computer, is examined. Provided that the initial tsunami profile can be determined within a few minutes after an earthquake by such a method as proposed by lzutani and Hirasawa, the tsunami numerical simulation based upon the linear long wave theory can be finished within two minutes and give practically accurate tsunami heights at every 200m along the castline of the Sanriku district extending from 41°30′N. to 36°20′N.

Introduction: Self-affirmation is known to buffer the development of anxiety symptoms into depressive symptoms, and a study during the early days of the COVID-19 pandemic revealed a role for this self-affirmation. In Japan, the COVID-19 pandemic has occurred repeatedly, and at this point (November 16, 2022), prior to an eighth wave. The possibility of ameliorating the psychological effects of this prolonged COVID-19 pandemic through efficient interventions targeting self-affirmation will be examined. Method: Study dates: June 25, 2020; September 25, 2020; February 10, 2021; November 24, 2021; February 7, 2022; August 31, 2022 Survey participants: Registered monitors of the research company (Neo Marketing Co., Ltd.) Each 1,000 respondents Questionnaire:1)Attributes: gender, age, region, number of family members 2)DASS-21 (Depression, Anxiety, Stress Scale-21) 3)LSNS-6 (the Lubben Social Network Scale-6) 4)Self-affirmation CIPS (Clance Impostor Phenomenon Scale) Rosenberg Self-Esteem Scale (Japanese version) The self-affirmation scale (CIPS; Rosenberg Self-Esteem Scale) was measured from the 4th to the 6th survey. Contribution of each factor to depressive symptoms: The DASS-21 Depressive Symptom Scores from the 4th through 6th surveys were examined using Prediction One with the DASS-21 Anxiety Symptom Score, DASS-21 Stress Score, Connections Score, Rosenberg, and CIPS score as factors to determine their contribution. Results: At the time of the second survey (September 25, 2020), DASS-21 scores peaked and then declined. CIPS and Rosenberg Self-Esteem Scale scores showed no change from the 4th to the 6th session. The result of contribution of each factor to depressive symptoms by Prediction One showed anxiety symptoms contributed the most to depressive symptoms. Conclusion: A model in which self-affirmation prevents anxiety symptoms from progressing to depressive symptoms is reasonable until the 7th wave of the COVID-19 pandemic in Japan.

In this study, factors causing the underestimation of morphological changes due to tsunami-induced sediment transport in Kesennuma Bay with narrows during the Great East Japan Earthquake and Tsunami have been numerically investigaed. Based on the estimation, the saturated concentration of suspention model was improved. It was found out that strong unsdeady flows occerred at narrows. The numerical results from conventional saturated concentration model implied that at the narrows, suspension concentration and sediment supply from the bottom to the suspension were limited by high concentration in suspension, leading to underestimation of morphological change, i.e., erosion and deposition. By considering effects of strong unsteady flows on concentration of suspention, a new form of saturated concentration model based on log-wake law and Kármán constant theory has been proposed. Numerical results of the erosion and deposition in Kesennuma Bay were improved. It is expected that accuracy of evaluation about not only morphological changes but also inundation area and damages are improved.

 An integrated tsunami model consisting of models for simulating tsunami inundation, drifting objects and sediment transport, was newly developed to evaluate the effects of these multiple phenomena. A scenario of complex tsunami damage enlargement in a bay with bottleneck was revealed. The tsunami hazards in Kesennuma City, especially at the inner part of the bay such as Shishiori area, were enlarged by erosion in the bottleneck of the bay. The bathymetric change increased the drift distance of the drifting vessels. In addition, through the tsunami fragility functions based on dataset of actual damaged building and numerical results, it was evaluated that the 200 - 1,800 wooden buildings were washed away owing to sediment transport. Furthermore, it is found that the estimation accuracy of damage scale by the conventional fragility functions was suitable, although the estimated building damage near the sea and inland was under and overestimated, respectively.

 In this study, it was found that through the numerical simulations of sediment transport in case of the 2011 Great East Japan Earthquake and Tsunami in Rikuzentakata City, the water level of the entire city area increased roughly by 1 m through the damage of the seawalls and the water level on the eastern and inner parts also increased remarkably because of the sand dune and riverbed erosion. Moreover, such damages caused the return flow near the coast line to amplify by about twice. On the other hand, using offshore tsunami waveforms, this study proposed a quantitative estimation method of the magnitude of return flow, M_RF. Estimation of the M_RF was then performed and applied for the Nankai Trough Great Earthquake and Tsunami. The return flow around Tosashimizu and Tokai Area would be equal to or greater than those on Rikuzentakata City or Onagawa Town during the 2011 tsunami. Based on lessons from the 2011 tsunami, since M_RF was larger than 0.0003, the typical value in Sanriku Coast, M_RF will be important reference for consideration among other countermeasures against future tsunamis.

 A reliable 2-D tsunami inundation model in an urban area is investigated through the 2011 Tohoku tsunami case. Each building is modeled as the uplift of topography with 5-m, 1.67-m, or 55.6-cm resolution on a supercomputer, and it was found that a resolution higher than 1.67 m is necessary to have a well-converged solution. We evaluated the 5-m resolution models that incorporate the effect of buildings as bottom friction or drag force by comparing to the above-mentioned 55.6-cm model. As a result, the drag-force model could provide accurate solution with a constant parameter independently of input wave, while the bottom-friction model required a higher parameter to reproduce a tsunami with larger depth.

The tsunami deposit is tend to be preservable in a coastal lake. In this research, the hydraulic experiment on tsunami rushing into a coastal lake was carried out with fixed bed condition. The experimental results showed that hydraulic jump occurred according to inundated flow flooding into the lake, and the state of flow changes complicatedly with the lapsed time. The changing flow state was depending on a lake scale. Furthermore, the water level and the flow velocity on the bottom became maximum near the dune back, and the maximum flow velocity was decreased when lake depth deeper. The results could give important knowledge for the depositional process of tsunami deposit in a coastal lake.

A numerical modeling of sediment transport was performed to investigate coastal geomorphic change due to the 2011 Tohoku Earthquake tsunami in Rikuzentakata City. The simulation was verified for observed inundation process and height, and measured topographic change and sediment deposition. The role of sediment transport on the modeling of tsunami inundation was also investigated.The numerical results revealed that the most of the sand dune was flushed out by the first wave, especially during the strong return flow. Such strong flow and total erosion of sand dune could also occur elsewhere, in case when a tsunami inundate a plain with moderate distance by shore-normal direction to the coastline.

An action/activity to collect document, photos, pictures and to open them for users has been performed by public, private sections, academia and citizen in order to succeed memories and the lesson of the earthquake disaster to future disaster, but problems have been pointed out in collecting/recording and arrangement, preservation, which are introduced in the paper. Particularly, we have a big problem how we can promote profit of archive utilization while the memory of the 2011 East Japan great earthquake disaster is fading away among the people. And we report the activity such as "Michinoku-Shinrokuden" carrying out in Tohoku University.

Trapping mechanism of floating objects during tsunami due to aligned trees was investigated through field surveys and hydraulic experiments. From the hydraulic experiment, the physical factors related to roadside trees and explaining the capture of floating objects were obtained. In addition, we show the maximum momentum limit at which trees fall when floating objects were trapped. Using the floating objects capture evaluation method of the trees that considered falling of trees, a verification case was performed knowing the specifications of the trees and floating objects in Tagajo city in case of the 2011 Tohoku earthquake and tsunami. We proved that the trees in Tagajo city did not fall even if it trapped floating objects during tsunami, generally agreeing on the quantity of the trapping ratio.

The advanced tsunami disaster mitigation system was constructed in the Tohoku district. The system displays an inundation range corresponding to the high tsunami observed in a GPS buoy. When the tsunami of 11 March 2011 was generated in Tohoku, the tsunami was observed in those GPS buoy. However, this advanced system did not operate by the blackout of the computer. We studied about the information to be supplied to the case which this system operated. As a result, we were able to judge that the information of this system might mitigate of tsunami disaster.

A mathematical simulation of tsunamis was developed based on the proposal of a fault model and modeling technology in 1960, and applied to the reproduction of historical events, risk assessment, hazard maps and quantitative forecasting system by the JMA. More detail and important data from earthquake tsunami monitoring in real time has become available to improve the mathematical simulation. Updates on the progress in this field and its utilization to provide evacuation warnings are described.

The purpose of this study is to discuss design of mitigation by using coastal forest in a practical field, and to evaluate the role and effect of coastal forest. In this study, Iwanuma-Natori coast in Sendai Bay was selected as the research site. The field investigation was carried out to measure the topography inside of coastal forest and the forest condition. To evaluate the effect of coastal forest, one-dimensional numerical simulation was carried out based on the field investigation. And the effect of several plan of countermeasure including the afforestation of forest and the stabilized dune was examined and discussed for implementation in the field.

In this paper, characteristics of tsunami propagation and runup are briefly introduced by giving examples of near and far-field tsunamis that are not well known. The evidence of tsunami's impact such as stones and rocks carried on the land by the tsunami is very helpful to understand its power and wave force. Finally, the type of tsunami disasters, and their mechanisms and criteria are summarized referring to the past disasters due to the tsunamis in Japan.

We have developed the two different systems of the communication performance to estimate the influence that communication performance on parallel of the tsunami numerical analysis. The one of systems is a PC cluster that connected with an internal high-speed switch, and another is the system that connected a PC on a network. On two systems with different communication performance, we were able to clarify parallel processing of the tsunami numerical analysis and relations of the communication performance. We are going to use these systems for the tsunami numerical analysis in real-time, however, the effect of the parallel one is not enough when the grids exceeds 900x300.

 はじめに 2004年12月26日にスマトラ島沖で発生した巨大地震における津波災害は極めて激烈なものであった。この中で、沿岸の森林生態系であるマングローブ林とその土地は、どのように破壊され、あるいは如何なる防災機能を発揮したのだろうか。最大波高が10mを超えるような巨大津波の経験を踏まえて、今や、マングローブ林とその土地が有する防災機能を適切に理解し、沿岸域の防災林整備に資する指針を作り上げることが必要とされている。 マングローブ生態学・津波工学・地形学などの専門からなる演者らは、地震直後から、文科省振興調整費、科研費、国土地理協会、林業技術協会などの助成を得てタイとスマトラの各地でマングローブ林がどのように破壊された森と土地に関する詳細なデータを作成し、津波伝播に関するシミュレーションを実施し、現地での適合性を評価し、これらをもとにマングローブ構成種の津波破壊に対する抵抗力を評価してきた。昨年末までで、各地の実態調査と一連の評価もほぼ終了する段階までこぎつけ、今後は破壊された生態系の修復を考察する段階に移る。そこで、これまでに調査し、解析して得た知識の概要を報告し、今後展開される防災機能としてのマングローブ林の有効活用や植林活動の展開に少しでも役立てることを期待したい。 津波に対するマングローブ林の応答タイプ ：熱帯の広域で津波が襲来したために、極めて多様な応答の例を現場で検証する機会に恵まれた。マングローブ林と言えども、限定的な立地位置（潮間帯の上半部）、多様な植生・生活形（樹種・森林規模・樹木サイズなど）、微地形と堆積物（砂質・泥質など）の相違があり、これらの条件と津波のエネルギーとの関係が整理されて理解されることが必要である。その際、マングローブ樹木の破壊は、強い破壊から順に抜根流亡、侵食流亡、曲げ折れ、せん断破壊、倒壊、傾動、枯死、生存と類型化できる。なお、侵食流亡・枯死は波力と樹木の力関係の次元とは異なる。また、抜根流亡とせん断破壊は波力の評価が困難である。 地形変化に伴うマングローブ林の破壊 ：浜堤など砂質の微地形が津波で容易に侵食されることで、樹木が大量に流亡する事態が波高3m以上の箇所で広く発生した。マングローブの根は発達深度がごく浅く、地盤の侵食に極めて弱い。一方で粘土質の干潟などは侵食に強く、波高が5mを越えても堆積物の侵食は軽微であった。バンダアチェの一部では波高が10mを超え、泥質・泥炭質の地盤が大規模に侵食された。津波に伴った堆積が行われた場所では流亡が発生しなかった。 河口部や澪など微地形的な低所は、津波が集中し、周囲に比べて強い破壊が発生したが、一方で比高1～2m程度の浜堤は越流する津波の波力を減衰することには余り寄与しなかったようである。 マングローブは、津波でどう破壊されたか ：湾口で波高3－5m程度の遡上が見られたナムケム、河口部を中心に6m内外の波高に達したカオラック、河口や沿岸低地で波高10m＋～5m程度の津波を蒙ったバンダアチェを対象に、利用しうる最良のデータを用い、現地計測を重ねて津波伝播のシミュレーションを行い、同時に破壊状況の計測を行った。この結果、特にリゾフォラは、津波エネルギーと樹木破壊の関係に極めて明瞭な関係式を導くことが出来、エネルギー分布と破壊状況の空間的な適合性の相応の相関が見出された。 もし、マングローブ林が ：直径が30cm程度の（樹齢数十年？）樹木からなる森がエビ養殖池が開発される前の状態で、バンダアチェに存在していたら、7万人に及んだ死者行方不明者の数がこれ程に達することは無かったのではないかと思われる。現在、その評価のための最終的な作業を実施している。

Although the activity to evaluate the disaster reduction capacity at each area by the interviews and the questionnaire has been started, the target is limited into the local government and autonomy. The present study aims to add residents for the evaluation focused on the tsunami mitigation and evacuation system at the coastal area, which is Shizugawa in Miyagi prefecture, one of the tsunami prone area in Japan. The gap of recognition and awareness between residents and autonomy should suggest us the disaster reduction capacity as well as issues for mitigation at the community. The request for improvement value (RIV) is introduced to define the issues for disaster mitigation especially tsunami evacuation, which results are valuable to discuss the countermeasure among the residents, leaders, and autonomy at the community.

Sendai Science Museum gives the opportunity for all Junior high school students in the city to take science experiment, one of which is the topics of natural disaster in the geology. The present study aims to know the efficiency how students could learn about the disaster through using the educational material, which can demonstrate an earthquake, liquefaction and a tsunami. The course tries to simplify a phenomenon by models in the laboratory, and to let them be interested in the contents by adding computer simulation, internet, and video. We found by the questionnaires before and after that the experiment course is very practical to understand the mechanism of natural hazards, and to let some students renewed fear of the disaster The free answer in the questionnaires suggests that the consciousness of the evacuation for tsunamis become high when students understand die fearfulness of the tsunami.

The fishery boast damage and its damage reduction plan are discussed in the present study in the coast region of Miyagi where an probability of an earthquake occurrence within 30 years is expected to be 99% probability. Although the countermeasure on the land against the tsunami attack have been stared by constructing the wall and wave-break and making hazard map, less one on the sea is carried out at the present. The evacuation flow for fishery boast is discussed by the process of issuing warning, decision, and making action, depending on the location and conditions. A hazard map on the sea tried to be made by adding the information of arrival time, maximum water level and velocity and an area to cause the boat damage.

A well-designed system for evacuations after warning issues is essentially necessary to reduce human loss. A lack of tools to evaluate an evacuation system lets such problem remain for long time. The objective of the present study is to develop the evacuation model simulating the behavior of human and vehicle by using the network model in the case of a tsunami attack. One of important functions in the model is to include route self-selecting/alternative model at several crossings by interacting and compiling human behaviors and tsunami impact, road condition, and people recognition of geometry. And walking and vehicle speed with function of density and condition on a road can be also included into a model. The validity of the model is examined in the case of the 1993 Hokkaido nansei-oki tsunami at the Aonae area, Okushiri, Hokkaido. The number of survivors and casualties estimated by the model shows good agreement with the reported and the main routes for evacuation to the hill simulated by the model are same as those by the eyewitness accounts.

On December 12,1992,5 : 29 a.m. UTC (1 : 29 p.m. local time), a magnitude M7.5 (USGS) earthquake struck the eastern region of Flores Island, Indonesia. A highly cooperative international survey team was formed, consisting of twenty scientists and engineers. Our Japanese team visited Indonesia on December 25,1992 to January 10,1993 and managed the field survey on earthquake and tsunami disasters. The first tsunami was reported to reach the shore of Flores Island within five minutes after the earthquake, because it is characterized as an extremely near-source event. About 1,000 people were killed by the tsunami. The maximum runup height measured is 26.2m at Kroko. Through the questionnaire the human behavior at the moment of tsunami attacking was studied. The lessons from the tsunami disaster will be useful for the Tokai tsunami prepardness in Japan.

In the 2004 Indian Ocean Tsunami and the 2011 Tohoku-Pacific Ocean Earthquake Tsunami, large-scale topographical changes occurred along the coast due to huge external forces, which had a great impact on subsequent restoration and reconstruction plans. We conducted long-term observations, surveys, and numerical evaluations of topographical changes in Thailand, Sri Lanka, and Tohoku, and predicted future topographical change scenarios. In Thailand, we analyzed the data of photography and photogrammetry by drone and summarized the relationship of the topographical recovery process. In Sri Lanka, we proceeded with particle size analysis and paleoenvironmental analysis, recognized old tsunami deposits, and clarified past environmental changes. On the Tohoku coast, the amount of change in beach topography was estimated from the data before and after the waves, and the relationship between parameter setting and reproducibility could be clarified by sediment movement analysis.

We comprehensively examined the reconstruction process put into place after the Great East Japan Earthquake. Furthermore, we made policy recommendations for "creative reconstruction" in the event of future disasters. Based on the Japan's reconstruction philosophy and the physical effects of the earthquake and tsunami, we categorized the disaster caused by the Great East Japan Earthquake and the subsequent reconstruction. We considered policies in the fields of housing/towns, industry and employment, school education, nuclear disaster, human power and financial systems, memories and traditions. As a result, we proposed 43 policy recommendations in 6 categories (Reconstruction Philosophy through Disaster Mitigation, Focused Policies on the characteristics of damage, Policies for the self-sustaining of residents, Upskilling of local government, Support of local governments by the national state and prefecture, memories and traditions to be implemented in the next disaster).

In order to spread the effects of disaster prevention education widely from children to families, we established a form of delivering class that introduces the phenomenon of disaster from the viewpoint of natural disaster science from the conventional educational method and introduces it in the form of science delivery. This delivering lesson consists of three parts. The first part is learning by lecture. The second part will let the group of several people experience the game thinking how to act on the scene at the time of the actual disaster. In the third section, the result of the game experienced was discussed within the group and the result of the summary was presented. We surveyed by questionnaire before and after this program implementation and about one month later. From this result, children 's disaster prevention awareness improved, and the children discussed with their families in the family and found that many children carried out countermeasures against disasters.

This study performed geological and geomorphological field surveys and laboratory analyses at Sanriku coast of Japan. We revealed thousand-years-long paleotsunami histories at several places. Especially, we found possible evidence of AD869 Jogan tsunami event at central to northern Sanriku coast. This results should be important for estimating the source model since our results define northern extent of the sediments deposited by the Jogan tsunami. Geomorphological and geological research, studying the long term (103~105 year scale) crustal movement, further revealed that northern Sanriku area was slightly uplifted while the southern part was subsided. Numerical modeling for sediment transport is very useful to constrain tsunami source if distribution and thickness of tsunami deposits is used as modeling boundary condition. Sensitivity test of sediment deposition at different geomorphological settings will provide further constraints for tsunami source model.

On March 11, 2011, the huge tsunami caused by the great east Japan earthquake devastated many infrastructures in pacific coast of north eastern Japan. Particularly, the damage of outflow of bridge girders caused a traffic disorder and these collapse behaviours led to delay of recovery after the disaster.After 2011 tsunami, disaster prevention and mitigation techniques are actively developing in coastal infrastructures and establishing prediction method for tsunami disaster is one of the severe issues toward the next millennium tsunami. In this study, a multi -level and - physics tsunami simulator based on the Smoothed Particle Hydrodynamics (SPH) Method has been developed. The last level (Level-2) can treat multi-physics problem, and the simulator can predict bridge wash out accidents during tsunami by using one of the modules of multi-physics simulation. Each level can be connected by a proposed virtual wave maker.

We find that the disaster management and mitigation measures conceived from the perspective of protecting society is insufficient to address the national crisis due to Nankai trough earthquake or Tokyo inland earthquake whose damage must exceed the estimated damage of this time. This study discovers the weakness against disasters in modern society using the “reversal thinking” which investigates how disasters can attack human society and increase damage effectively. This process profiles the “worst scenarios of disaster” which can extend damage to the level of national crisis. We suggest policies and present action plans to the independent problems. Then, sorting final consequences and separating them according to the commonality, we propose disaster resilience and concrete action plans to prevent them. The most important conclusion is that it is necessary to have a new organization such as Ministry of Disaster Resilience to intercept these national crisis.

Sedimentological and micropaleontological analyses of terrestrial and nearshore to offshore sediments recovered from the coast of the Sendai Bay were performed to clarify the processes of sediment transport and deposition by the tsunami retreat. The distribution pattern of sediment grains and diatom frustules showed seaward migration after the tsunami event. It has been suggested that sediments originally distributed in terrestrial and coastal zones were transported offshore due to the tsunami backwash. The distribution pattern of planktonic and benthic species living in offshore zones showed slight evidence of landward migration by the tsunami. This suggests that landward redistribution of sediments by the tsunami run-up did not occur in the offshore seafloor of the study area. It is possible that tsunami backwashes induce sediment flows that transport a large amount of coastal materials seaward.

The purpose of the research is to evaluate the millennium tsunami hazard ,which is a low frequency giant tsunami disaster which occurs once in about 1000 years, by complementing based on scientific techniques, such as geology, sedimentology, topography, and seismology, in addition to the historical fact and documents in literatures. Millennium tsunami hazard evaluation was carried out in Okinawa and the Tohoku district. First, a possibility that 850yrBP and two terms of 1100 yrBP would be suggested by the investigation and analysis of a coral fossil (tsunami stone) which were launched from tsunami in Yaeyama Islands in addition to the 1771 Meiwa tsunami was shown. Furthermore, interdisciplinary investigation is conducted in Sendai plane that 1260yrBP and 2050 yrBP would is added to the 869 Jogan earthquake. Examination of the tsunami damage function etc. which were obtained by the 2011 Great East Japan Earthquake was also carried out.

Mode of sediment transport by the 869 Jogan earthquake tsunami was estimated by analogy with grain-size composition and facies of the tsunami deposit. In addition, initial hydraulic condition of tsunami-induced currents was sedimentologically evaluated to increase knowledge on behavior of tsunami run-ups. Landward fining of the sand layer that comprises the Jogan tsunami deposit was clearly identified on the basis of the grain-size analysis by the laser-diffraction gram-size analyzer. This is consistent with the results from our hydraulic experiments of sediment transport and deposition of tsunamis. It is clarified that mode of fining of sedimentary layer can be treated as important criteria that reflect the energy dissipation of tsunami run-ups. These criteria may provide physical- geographic condition for theoretical understandings of formation of coastal topography. In addition, they may give us indispensable knowledge on developments of urban and industrial infrastructures of coastal areas. Changes in foraminiferal assemblages after the 2004 Indian Ocean tsunami were clearly demonstrated by the micropaleontological analysis of sediment samples collected from the southwest coast of Thailand. This implies that traces of turbidity currents induced by tsunami backwashes can be preserved in submarine sedimentary environments. Therefore history of tsunami occurrence is possible to uncover based on sediment excavation on the ocean. These results were presented and gained scientific attention in the XXIV General Assembly of IUGG that was held in Perugia, Italy, in July 2007, as an actual example of tsunami disaster and sedimentation.

People could recognize the risk of natural hazard by compiling the information on the hazards and their situation through the cognition and perception. Then they could start to evacuate for safety area after checking the route. Therefore, we aim to study on the information through cognition and judgment, and evacuation behaviors. In this study, we carried out the data-base, making hazard map, experienced oriented education, practice for evacuation at the community to research the response of the people and government staff for each information and situation. On 26 May 2003, the Miyagi off earthquake with intensity of 4-6 happened and the tsunami warning was issued. However, only 1.7 % of them could evacuate from a expected tsunami. We try to find the reasons why so small number of the people could make the action. The interviews and questionnaire suggests the reasons are strong dependence on the information more than self-judgment, and complex/fixed idea even though short time was allowed for evacuation. In order to improve the current situation, we try to introduce the two kinds of the efforts at the community and school ; one is the community based workshop to make the design of evacuation for the local and second is the disaster education at schools through experienced work, which are effective to improve the awareness and disaster prevention.

In Japan, tsunami, storm surges and river flood prone areas overlap each other in some alluvial planes facing the ocean. In Osaka, three kinds of flooding are very popular, and In Tokyo and in Nagoya, storm surges and river flood may simultaneously occur. Especially, in 2005 we had hurricane Katrina disasters. In New Orleans, the most disastrous storm surge flood on record was observed. Even though in developed country such as USA and Japan, we have to remember storm surge disasters. Paper type hazard map has some restrictions of information for residents. As an alternative trial, we developed a passive type hazard map with CG on the basis of numerical simulation. For example, the tsunami hazard map at Owase, Mie is very effective on the evacuation training as well as disaster education. We developed the making procedure of hazard map in which GIS is a fundamental map for some information through the Internet. Moreover, if we can use the simulation technique of evacuation, it will be made clear quantitatively about the enlightening effectiveness of decision making about beginning of evacuation and evacuation route on survival rate. Furthermore, we can not neglect the simultaneous occurrence probability of following two phenomenon combination with storm surge, tsunami and river flood from the vie point of disaster reduction. It was found to be very rational that a base map of inundation in residential area is firstly given by long period flooding and after that additional inundation depth due to short period flooding is required. The former is tsunami and the latter is storm surges. We succeeded to make a hazard map of inundation due to tsunami and storm surge under simultaneous occurrence.

In this research, it aimed at the development of the disaster integrated scenario simulator. This simulator synchronized three submodels those are a flood analysis, a disaster information transmission, and the evacuation shelter action. The simulation system has achieved the delivery of the data between subsystems and the visualization of the calculation result by storing the calculation result in GIS at the same time as managing the input information with the simulation system based on GIS and making it cooperate. When the urban flood analysis system that enables the scenario assumption constructs it in urban facilities and the land use, we collect basic information to construct the heavy rainfall analysis system of the heavy rainfall disaster in Tokai district and examined the development process of the piping that become a factor of banks collapsed and the flood runoff analysis technology that used the radar Automated Meteorological Data Acquisition System. In the construction of the information transmission analysis system that enabled the scenario assumption, we analyzed resident's and administration's information acquisition and use, and the resident's decision making mechanism of information acquisition and evacuation behavior in the approach process of the typhoon. In addition, we analyzed the relation with the resident's information acquisition, valley recognition and risk cognitive the case of the heavy rainfall disaster in Niigata, 2004. In the construction of resident's evacuation behavior simulation that that synchronized with the flood and the information transmission, the research on their decision making of evacuation behavior needed as the assumption was chiefly accomplished, and the decision making model of the prototype was constructed. In this research, the integrated scenario simulator was developed preceding it for the tsunami disaster that the research results have been accumulated, and application to the river flood was tried. Moreover, we aimed at the reflection of efficiency improvement of the data format, calculation processing, and the result of the survey of the resident's behavior at the disaster in the system.

For the improvement of the accuracy of far-field tsunami warning system, we studied (1) Mechanism and characteristics of multiple reflection of tsunamis incident on a continental shelf, (2) An estimation method of tsunami source region by using the real-time observation data, (3) Characteristics of dispersion effect of tsunami during the propagation and run-up process. For the study (1), we derived an analytical solution of tsunamis which are obliquely incident on a offward-finite constant slope. The incident waveforms are assumed to be transient. Based on the solutions obtained, characteristics of transient tsunami propagations on the slope are discussed in terms of the several conditions of incidence such as horizontal incident wave scale, incident angle and incident waveform. When tsunamis are incident almost parallel to the shoreline, multiple reflected waves reveal and are trapped on the slope. The solution indicates that the interference between multiple reflected waves and incoming incident waves could be a contributing cause of conspicuous amplification of tsunamis on the slope. For the study (2), we developed an estimation method for tsunami source region by using the hypothetical offshore tsunami gauge. The method enables to estimate the fault parameters of W and L (Width and Length), which reflects the horizontal extent of tsunami source region, within 20 % of estimation errors. For the study (3), we developed a numerical model with Boussinesq-type equations, which enables to estimate the dispersion effect during the process of tsunami propagation and run-up. The model was validated through the case study of the 1983 Nihonkai-Chubu earthquake tsunami to obtain the better estimate of tsunami height to explain the observed tsunami height along the coast of Japan sea.

Tsunamis have great hydrodynamic energy and have distinctive hydrodynamic effects on coastal regions. Recent geological studies have shown that a record of a tsunami inundation of a coast is preserved in tsunami deposits. Tsunamis transport large amounts of marine water and sediments inland, and seawater and sand invade coastal lakes and marshes. Moreover, tsunamis often move masses of rocks (Imamura et al., 2001), forming great onshore mounds or submarine bars. To interpret such tsunami records and estimate their ages, we must identify and study tsunami deposits. For example, multiple marine sand deposits found in excavations along the coast of northeast Japan suggest that repeated prehistoric and historic tsunami inundations affected the development of the coastal plain throughout the late Holocene (Minoura and Nakaya, 1991). However, the mechanisms of material transport -including the accumulation of thick mounds of marine sand and large-scale movement of huge rocks -by tsunamis are still unclear. Moreover, the topographic and geologic effects of tsunami sedimentation have never been fully considered, and the technological evaluation of tsunami sedimentation from the viewpoint of the impact on people and disaster planning is still insufficient. It has also been thought that earth-science methods cannot be applied to the study of tsunami deposits. In this context, many scientists, engineers, and historiographers have recently started coordinated studies on the recognition of tsunami deposits and on tsunami-induced material transport and environmental modification. Interdisciplinary studies of tsunami sedimentation will both clarify tsunami material transport mechanisms and establish criteria for theoretical understanding of the role of tsunamis in the development of coastal topography. The results of these studies will be applied to actual tsunami events, and will enable the specific disaster assessment of future tsunami inundations.

An objective of this research is to develop an early detection method for near field tsunamis. For this purpose, the tsunami generation mechanism, the use of the Rayleigh waves and the sea surface disturbance preceding tsunamis has been investigated, with the results shown below. 1. On the relationship among tsunamis, Rayleigh waves and sea surface disturbance. The dynamic tsunami simulation method that estimates both the dynamic ground displacement considering the fault rupturing and Navier-Stokes equation in fluid domain has recently been developed. Using the method, the relationship among tsunamis, Rayleigh waves and sea surface disturbance has been investigated for the early detection. 2. On the characteristics of Rayleigh wave propagation. From the dynamic tsunami simulation, the amplitude of the Rayleigh waves and the sea surface disturbance has-been found to become larger in the front area of the fault than that in other area. Especially, the amplitude is remarkably larger in the direction of the fault rupture propagation. Using tidal records in 1993 Hokkaido Nansei-Oki tsunami and the strong motion records in 1999 Chi-Chi Taiwan earthquake, the amplitude and the direction of the propagation have been investigated to confirm the above-mentioned characteristics. 3. On tsunami run-up simulation using the VOF and the Nesting technique. In the dynamic simulation, SOLA-SURF method was used in fluid domain simulation, where only vertical wall conditions are allowed because of the limitations of the method. Thus, to simulate the tsunami run-up, we have removed the limitations using of the VOF and the Nesting method.

This study aims to study the mechanism of landslide-induced tsunami by sedimentrological approach using the tsunami sedimentation. A tsunamigenic sediment layer has been discovered in fluvio-alluvial sequences on the northern coast of the Marmara Sea, northwestern Turkey. The layer is consisting of unsorted silty coarse sand including landsnails and charcoal fragments. The AMS radiometric ages of the shells have been estimated at around BC400, AD300, AD400, and AD1,000. It is proposed that a tsunami occurred in the Marmara Sea in the middle of 11th century and invaded the fluvial plains. The older fossils were derived from the underlying horizons, and we suggest that buoyancy materials such as landshells and charcoals were isolated from liquefied sediments durlng submarine sliding. Slope failing of coastal blocks triggered by fault movement generated tsunamis, which might have transported floating materials to the backshore. The simulation model for tsunamis caused by landsliding and debris flow is proposed and compared with the result from the hydraulic experiment model with an open-channel. We applied nonlinear long-wave theory integrated over a layer with non-horizontal bottom/interface as the governing equation for the numerical model. We assume hydrostatic pressure distribution, and uniform density and velocity distributions in each layer. For the case of tsunami generation by landslide, the sea water is modeled as an upper layer for wave generation and propagation, and the landslide is modeled. We used the staggered leap-frog scheme for the linear terms and the up-wind scheme for the nonlinear terms in this study. The leap-frog scheme is a central difference scheme with a truncation error of the second order. Three parameters/coefficients of the bottom friction, the horizontal viscousity and the interactive force between landslide and tsuami rushing into water are examined through comparison with the results of hydraulic experiments. We found that the Manning coefficient of 0.12 and horizontal viscousity of 0.01 are recommended for landsliding in this study. Although the interactive force is significantly important for a tsunami generation, a more detail analysis is required to determine a value of its coefficient.

An optical hydraulic-pressure gauge for an optical ocean bottom tsunami meter was developed using a frequency, shifted feedback laser with a rolled fiber sensor based on optical frequency domain reflectometry. Measuring the optical path length of the fiber, the hydraulic pressure is calculated. The sensor consisted of an 870 m-long bare dispersion-shifted fiber rolled on a hollow cylindrical aluminum bobbin, and its pressure sensitivity was confirmed as -2.34 10^<-11> /Pa. The accuracy of distance measurement was 10^<-9> using the frequency shifted feedback laser oscillating at 1.55 μm. Then the accuracy of pressure measurement using this system was 62 Pa, which corresponds to a depth of 6.2 mm and is sufficient performance for tsunami-measurement applications. Moreover, an origin with a field-spread of a tsunami was estimated using the reverse propagation technique analysis. This draws the wave crest lines to the maximum high-water level point and zero-cross point of the first wave of tsunami about each of two ocean bottom tsunami meters, and estimates the intersection as the origin area. As a result of carrying out a simulation about the tsunami network for the Pacific rim, by adding ocean bottom tsunami meters to the Hawaii Islands circumference realized that an origin area could be estimated with less than 20 % of error. On the coast of our country, human life is taken by tsunami and it is inflicting serious material damage frequently. It is indispensable to damage mitigation by tsunami offering exact information promptly. Real-time multi-point measurement is possible by the multiplexing the laser hydraulic pressure gauge using a frequency-shifted feedback laser. A tsunami numerical simulation can grasp correctly the scale and arrival time of tsunami. If the measurement network by the ocean bottom tsunami meter of a wide area based on this research result is realized, an exact tsunami warning can be issued and it is expected to minimize the damage.

The present study aims to develop a numerical technique to simulate generation and propagation of tsunamis with higher accuracy, and to evaluate effects of dynamic seabed displacement due to seismic faulting on tsunamis. In contrast with the conventional one, the new technique we have developed takes into account the dynamic seabed displacement as well as acoustic water waves. In principle, the present simulation is made up of two steps. The first is earthquake ground motion simulation for which the 3-D boundary element method (BEM) is used, and the second is tsunami simulation for which the 3-D finite difference method (FDM) is used. This is based on an assumption that the seabed-sea water system can be regarded as a weakly coupled system. Due to this assumption, the dynamic displacement of the seabed that includes the staticdisplacement is simulated first, considering rupture mechanismof seismic faulting. Then, velocity associated with the seabed displacement is input at the bottom of the sea water, and sea water disturbance is simulated by solving the Navier-Stokes equation. Results of the two-step simulation are represented in terms of not only snapshots but also animated figures, in order to facilitate evaluation of validity of the simtulation. The dynamic seabed displacement and the acoustic wave are found to give a remarkable increase in the water wave height especially in the near-fault area, as a result of superposed effects of the dynamic and static seabed displacements. In addition, the present simulation has demonstrated that short-period water disturbance is induced by Rayleigh waves that travels along the seabed with a velocity much higher than tsunamis. Finally, the present technique is applied to actual three tsunamis caused by recent earthquakes. From simulation for the 1998 Sanriku-oki earthquake (M6.3 ), the present technique proves to be able to simulate the associated tsunami to a satisfactory level of accuracy if the fault parameters are given with high accuracy. Simulation for the 1983 Nihonkai-Chubu (7.7) and the 1993 Hokkaido-Nansei-oki (7.8) earthquakes, is conduced by using seismically determined fault parameters and shows considerable difference between tidal records in the wave height and arrival time, mainly because of roughness of the fault parameters s and numerical models.

In this study, we developed a system that enables us to locate the possible impacted area due to significant earthquakes which occur anywhere in the world based on nighttime lights observed by the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) within the first 24hours after the event. The estimation is based on the detection of significant reductions or loss of lights in two consecutive nighttime images that one is taken before and one right after the event, for it can be expected that city lights will observably decrease after a large earthquake due to various reasons such as electricity failure, building collapses, evacuation to shelters and the suspension of commercial activities. This system goes through the following processing steps : 1) acquiring the earthquake hypocenter data through the Internet, which is for example announced by the USGS, 2) determining the sampled area of images by the attenuation formula of earthquake ground motion, 3) selection and download of the corresponding nighttime DMSP/OLS data from National Oceanic and Atmospheric Administration, National Geophysical Data Center (NOAA/NGDC), 4) estimating the damaged areas by analyzing the statistically significant decrease in light intensity of the images, 5) creating the thematic map to present the estimation results as geographic information, and 6) disseminating the result map widely and quickly through the WWW.The validity of our estimation has been established for some recent earthquake disasters such as the 1995 Hyogo-ken Nanbu Earthquake in Japan, the 1999 Kocaeli Earthquake in Turkey, and the 1999 Chi-Chi Earthquake in Taiwan.

The fore-arc region of northeast Japan is a terrane of extensive seismic activity and tsunami generation, and the coastal areas facing the Pacific Ocean have been repeatedly attacked by tsunamis. On July 13,869 a tsunami triggered by a large-scale earthquake invaded the coastal zones, causing extensive deposition of well-sorted fine sand over the plains. Sedimentological analysis and hydrodynamic modeling indicate that the sand layer was developed by the first wave of the tsunami, and we conclude that low-lying coastal zones are susceptible to extensive flooding during tsunami runup. Traces of large-scale invasion by older tsunamis are recorded in the coastal sequences at regular chronological intervals, and we indicate that the coastal plains of northeast Japan are in danger of tsunami disasters in the near future. The Pacific coast of NE Japan is notorious for the repeated invasion of tsunamis. The Sendai plain, however, has not been affected by a large tsunami since the occurrence of the Jogan event. Rapid urbanization has advanced to the coastal areas. It must be recognized that understanding of the timing and scale of potential tsunami occurrence is an urgent requirement, if tsunami mitigation efforts on the densely populated coast are to be successful. The elucidation of the cause and effect of regionally extensive invasion of the Jogan tsunami is indispensable not only to prevent a disaster but also to gain an understanding of tectonic processes of the fore arc. In this study, the Jogan tsunami deposits were studied using sedimentological analyses and hydrodynamic models in an attempt to make clear the mechanism of wave penetration more than 4 km beyond the coastline. More than 100 years have passed since the beginning of scientific observation in NE Japan, and inundation distance of tsunamis exceeding 2 km beyond the shore was never observed during this time interval . It is inferred from the historical documents that seawater inundation by the Jogan tsunami reached 4 km or more inland from the coast. The deep penetration of seawater mean an occurrence of unprecedented large-scale tsunami.

A well-designed system for evacuations after warning issues is essentially necessary to reduce human loss. A lack of tools to evaluate an evacuation system lets such problem remain for long time. The objective of the present study is to develop the evacuation model simulating the behavior of human and vehicle by using the network model in the case of a tsunami attack. One of important functions in a model is to include route self-selecting/alternative model at several crossings by interacting and compiling human behaviors and tsunami impact, road condition, and people recognition of geometry. And walking and vehicle speed with function of density and condition on a road should be also included into a model. The three kinds of field studies were carried out ; (1) determination of route self-selecting/alternative at the area, (2) human behaviors of individuals and group on a beach, and (3) evacuation drill to know the human behavior and judgment. The results from these studies are included into the model. The validity of the model is examined in the case of the 1993 Hokkaidonansei-oki tsunami at the Aonae area, Okushiri, Hokkaido. The number of survivors and casualties estimated by the model shows good agreement with the reported and the main routes for evacuation to the hill simulated by the model are same as those by the eyewitness accounts. Another aim of the present study is, therefore, to develop the model to estimate the starting time of evacuation at several stages by using the quantification method like multi-variable analysis. The parameters in the model, called a category scores, could be determined by the data on the tsunami evacuations in the past. Provided the earthquake intensity, location, experiences and time zone at each region, the ratio of the evacuation and its starting time can be estimated and be compared with the tsunami arrival time, which is useful to evaluate the present system against the tsunami attack. We applied the model to Miyagi prefecture along the coast and discuss the risk of the tsunamiattacks.

The first investigation on the tsunami caused by the earthquake offshore northwestern coast of Papua New Guinea (PNG) was carried out by the International Tsunami Survey Team (ITST) during the period of 31 July to 7 August 1998. On the evening of Friday 17 July a massive tsunami swept across the sand bar that forms the outer margin of Sissano Lagoon, west Sepik, PNG. Initial media reported that the tsunami struck west of the town of Aitape in the west Sepik province, hitting at least four villages. And the was 7 - 10 m and that up to 3,000 persons were killed or missing. This seemed to be an unusually damaging tsunami given the size of the earthquake (M=7). Members of the ITST decided that a field survey was necessary as soon as possible to try and determine the true value of the maximum run-up and to accurately map the run-up distribution along the coast. The survey to the damaged area confirmed the 7 - 10 m wave heights reported and found the place where the waves were larger up to 15 m and extreme overland flow velocities of 10 to 15 m/s. The severe damage and extreme wave heights were confined to a relatively short (30km) stretch of coast between Aitape and Sissano Villages and specially large along the sand bar the outer margin of Sissano Lagoon. These suggest that tsunami energy is concentrated in this narrow region. Although a tsunami is to be amplified in V-shaped bay, peninsula, island and ridge, the coastal line in Sissano is straight and the contour lines of water depth are almost parallel. Extremely large tsunami than estimated by an earthquake (M=7) might be caused by not a local bottom topography but a tsunami generation. Eyewitness of a loud bang, hot water, bubbles and foul smell suggest sea landslide or a gas explosion offshore triggered by the earthquake as a secondary mechanism of tsunami generation. Further field investigation and research on it are required to solve a riddle of the tsunami generation.

土砂の移動量を浮遊砂と掃流砂に分けて求めて計算を一様勾配斜面において基礎検討を実施し,この中で使用されている重要なパラメータとして流体中(海水中)の最大土砂濃度(Cs)や巻き上げに関する鉛直拡散係数がある.鉛直拡散係数は浅井・高橋(1998)による実験結果を引用することもでき,また,応答解析の結果でも範囲(0.001〜0.2)では,海底の変化は小さいことがわかった.一方,最大土砂濃度(Cs)による堆積量の違いは大きいことが判明した.これは,海水中に存在し得る土砂濃度(Cs)が大きいほど浮遊砂量が増大し,一旦巻き上げられた土砂が流れにより移動し易くなり,特に陸上部への堆積に寄与することが判明した.このCs値は,土砂の沈降と土砂を浮遊させる能力(乱流)に大きく関係していると考えられ,これに関する研究があるが室内実験に留まっているために,本ケースのような実際の現場で,しかもシールズ数がかなり大きいと思われる状態に適用することはできない.次に実際に,固定床での入射波条件を用いて,入間での移動床計算を実施した.全体的に海域で侵食傾向,陸側で堆積傾向であることが分かった.これは,押し波で入射した津波が,湾口の狭いしかも両側が切り立った入間湾に入ると,急縮の効果により流速値を増加させ,そこでの巻き上げ量を大きくして,陸上に運んだものと思われる.入間湾の地形は,今回の大規模堆積の原因の1つである.一方,Cs値の変化により地形が大きく変化していることも事実である.ただし,陸上部での堆積状態はほぼ同じである.現地調査で得られた70万m^3付近の堆積量を再現できたのは,0.3の時であった.従って,この程度の最大土砂濃度を仮定すれば大規模土砂移動をある程度再現できることがわかった.

Sedimentation processes caused by a modern tsunami have been discussed from the point of view of geologic and numerical investigations of the 1992 Flores tsunami in Indonesia. Geologic evidence on Babi Island shows an invasion of two waves with different direction and magnitude, which resulted in widespread deposition of marine sand on the north and south-southewest shores. On the latter, coarse and well-sorted carbonate sand with molluscan shells suggests that much more destructive waves swept across the southern coast as compared with the northern coast where the deposit included medium carbonate sand with a silty component. A physical explanation for such destructive waves on the southern coast of Babi is provided by a numerical simulation of the tsunami generation and propagation. The geologic and numerical results indicate that an isolated island surrounded by a circular shoreline or reef edge will be the hardest hit on the coast on the back side of the island relative to the tsunami source.

A tsunami is ususlly considered to be generated by an earthquake. Once fault parameters are given, the initial tsunami profile is calculated with the elastic theory. It is assumed that the vertical displacement of sea bottom is closely related to the fault movement. However, this assumption is not always true. 1) In case of the 1983 Nihonkai-Chubu earthquake composed of two faults, a secondary fault in the north fault and a non-seismic movement are necessary in order to explain earlier arrival of the actual tsunami than the computed tsunami for the major fault movement determined by seismic data. 2) In case of the 1992 Nicaraguan tsunami, in spite of a large tsunami, the earthquake was very weak, as 2 in the JMA intensity scale. Whether this tsunami was generated by the earthquake or by other mechanism was examined. It is concluded that this earthquake was a tsunami earthquake. 3) In case of the 1993 Hokkaido Nansei-oki earthquake, the first tsunami arrived at the western coast of Hokkaido 5 minutes faster than that generated at the place of the fault estimated from seismic data. This strongly suggests that other tsunami generation mechanism than the earthquake should be found in the area between the fault and the coast. 4)The 1883 Krakatau tsunami which was not generated by an earthquake but by a caldera formation was numerically simulated. A method is developed to stably simulate a sudden fall of water at the initial profile.

1992年9月2日1時16分(世界時)に太平洋中央アメリカ海嶺で発生したニカラグア地震(Ms=7.2)とそれによる津波のニカラグアへの影科を調査した。調査は9月20日から24日までの5日間、ニカラグアの太平洋海岸で3班に分かれて実施された。内容は海岸での「本震震度」「津波の最大水位と来襲状況」の聞き込み調査と「津波の痕跡、被害」の目視による調査、本震を含む地震と津波に関して現地でとれた記録の収集などからなる。これによって(1)津波の最大水位(平均海面上)にニカラグア太平洋全海岸にそっての分布、平均で4〜5m、中央部(エルトランシト)で最大で10m、南北方向へむかって減衰する、をえた。(2)本震震度はMM震度階で2〜3で、首都マナグアでは1であった。(3)最大水位の分布、検潮記録を総合すると長さ200km、幅100kmの低角逆断層の発生が津波の原因となっている。(4)被害は最大水位に比例し、エルトランシトでは海に面した住宅は壊滅状態であり、エルトランシト以外の4〜6mの水位の所では家の壁や戸の破壊が見られた。死者は全域で100名をこし、小供の占める割合が高いのが注目される。聞き込み調査によると津波の来襲はそれほど急激ではなく、除々に水位が増加したため逃げる余裕があった。(5)津波第一波は引き波であるという証言が少なからずあり、検潮記録の結果がうらづけられた。これは低角逆断層の特徴である。第一波押し波の伝播時間は44〜70分で、波数は3波程度であるとの証言を多くえた。これらの結果を総合すると(a)津波の規模にくらべ地震震度が小さく、展型的な「津波地震」である。(b)海溝での長さ200km、幅100km程度の逆断層による津波である。このことはカリブプレートの弾性はねかえりが津波を引き起こしたことを示している。(c)津波は市街地に上陸して減衰し、最大浸水距離で上陸時の水位の1/2になっている。これは長波が上陸時に保持する運動エネルギーを全て失った結果とみなせる。

本研究に参加した6人をフローレス島地震津波調査団として1992年12月25日ジャカルタに入り、26日インドネシア国気象庁の4人の研究者と調査活動の打ち合せを行ったのち、29日朝から1月5日夕刻までの8日間、最大被災地となったフローレス島東部のマウメレ市とその周辺海岸地域の調査を行った。今回の調査では、地震被害調査、津波調査、および現地余震観測の3つの調査を行った。マウメレ市は港を含め海岸地区の地盤液状化によるレンガ、およびコンクリート構造物の被害が著しかった。また山岳部道路の亀裂、段差発生、岩石崩落、路肩欠損などにより、交通路の確保の難しさが認識された。マウメレ市の東北方45kmの人口に人口約1300人のバビ島があり、全度が津波で流失し、推定約500人が死亡、または行方不明となった。バビ島はじめ津波被災地の約100名近い被災者にインタビューして被災時の様子を聞き出した。地震動そのものによって、家屋の倒壊、居住地内での地面の亀裂、山の斜面からの落石を経験してパニック状態となっているところへ、3分後には6,7mの津波に襲われた。海岸線すぐ近いところで、地震、津波が発生したときの生存のための避難活動の困難さ、問題点を聞き出すことが出来た。フローレス本島の東北端に近いクロコ村で津深は海抜26.2mに達しているところがあり、今回の津波が、昭和8年の三陸津波に匹敵する大津波であったことが判明した。被災地からジャカルタにもどって1月8日に、インドネシア国の気象庁関係者、地震研究者、バンドン工科大学の工学の教授などと、8時間にわたる発表討論会を持ち、インドネシアの国情に応じた地震津波災害対策と、将来の共同研究体制について話し合った。

The standard mechanism of tsunami generation has been explained based upon the fault motion. A tsunami initial profile is given by the sea bottom displacement estimated from fault parameters, on assuming a homogeneous fault plane. This method often gives an unsatisfactory result different from the observed tsunami. The present study aims to examine causes of this difference. The 1983 Nihonkai-Chubu earthquake tsunami is selected as one of examples, for which many evidences and witnesses are available. The effect of the heterogeneous fault motion on the tsunami generation and propagation is discussed in view of the frequency dispersion and the resolution of tide record. In order to satisfy the witnessed tsunami, a secondary fault is necessary for the north fault and aseismic creeping slips on the eastern side of the south fault. As an example of the tsunami generated not by a fault motion, the 1883 Krakatau tsunami is well simulated, on assuming a rapid caldera formation and on developing a method to stabilize the computation at the early stage of computation.

(1)流雪構および融雪溝の布設路線数・延長距離は年々増加傾向にある。青森県では年平均8箇所、約5kmの布設距離となっている。 (2)近年、融雪溝の設置が増大している。 (3)幅、底勾配の急変箇所、急曲部箇所数が年々増加傾向にある。特に、急曲部の箇所の増加が著しい。 (4)流雪溝や融雪溝の送雪能力よりもその能力に応じた運用方法の確立が重要となる。 (5)曲がりや勾配変化等は町域の形、流雪溝の配置形状、地形等によって定まり、どうしても避け難い状況にある。こうした弱点箇所が、全体の作業能率を落とさない為に、どの様に設計されなくてはならないかは極めて重要な問題となっている。 (6)現地調査により、構造的原因に関して流雪溝の閉塞状況を3箇所について把握し、勾配により閉塞箇所が異なることが示された。 (7)室内実験により、流雪溝屈曲部の閉塞の有無を雪塊の接近速度・硬さ・大きさの3項目により分類した。雪塊が屈曲部を通過するときに破壊される体積に着目し、雪塊の持つ運動エネルギとの関係から流雪溝屈曲部での閉塞条件を用いて、条件を1つにまとめることができた。連続して流れる雪塊を考え、その送雪能力を導きQ_W/Q_S≒4〜5であることを示した。 (8)流雪溝内の雪混じり流れをダイレタント性の流れとしてモデル化し、平均流速式を導いた。 (9)雪水二相流の流動現象についての観測をポリスチレン粒子を用いて行った結果、断面内の速度分布は水平方向にはほぼ一様となっているが、鉛直方向には大きく変化する分布となっていることが明らかとなった。

1、北海道から北陸に至る7市2町をモデル都市として選定し,現行流雪溝の運用状況と問題点を整理した。青森県内の各市町村の流雪溝諸元(流量,水路勾配,幅,急変箇所数,運用状況)調査を実施し、現行流雪溝の特性を抽出した。この結果、利用条件が気象、水理,地形,街区都市化進行状況でまとめられることが明らかとなり,流雪溝の設計条件の分類をした。 2、水路屈折部の雪塊流動現象および停滞・閉塞現象を室内実験で観測し,水路屈曲部における雪塊流動機構を検討した。これにより、屈折部を有する流雪溝の送雪能力推定式を提案した。 3、雪水二相流管内流動の観測を室内実験により行った。その結果、以下の点が明らかとなった。(1)乱流による圧力変動は低速域では清水の圧力変動とほぼ同じであり,高速域では清水の圧力変動よりも小さくなる。(2)雪塊の代わりにポリスチレン粒子(比重0.97,1.04)を用いての流動観測により,低速域では上層に浮遊集積層、下層に、沈降集積層ができるためにエネルギ-損失は清水時よりも大きく,高速域では固体粒子が断面全体に広がるために清水時のエネルギ損失とほぼ同一となる。また、この観則により、管内混相流の固体粒子速度の分布形が解明された。 4、排雪限界と流雪溝の設計条件に関する検討の結果,街区の条件によっては、水路の高さが排雪限界量を決めてしまう場合があり,この点の設計条件を明確にする必要があることがわかった。本研究の目的達成には、今後,(1)曲部・断面変化部の流雪能力の推定式およびその実験的検討,(2)雪水混相の乱流抵抗則,(3)直線部排雪限界と必要最低水深および雪塊投雪時の抵抗則を明らかにする必要がある。

伊豆諸島の島世界に関する3か年の調査研究によって明かになったのは、次の諸点である。まず、生業、儀礼、祭祀などに見られる民俗的対称性は、島修験や神官の関与を経ながら、七島を束として捉えうる島世界を形成してきた。それは、各島にある山を中心としたコスモロジ-を描いており、島全体の小世界である村落においても重層的に展開している。これは海上他界を設定する南西諸島のいわば「開かれた」島社会に対して、山中他界を設定する「閉じた」島社会としての性格を持つ。具体的には儀礼の執行者や村内の神仏、山と海への観念などに如実に表れている。次に、生産の諸活動についての調査に際して、島のさまざまな場所に関する人々の意識が明かになった。それによって、民俗的世界の集落・境界・異界といった空間のカテゴリ-は、生産・社会・儀礼などの諸側面と深くかかわっていることが、具体的に判明した。いわば、「語られた」「記憶された」空間を提示できたと考える。例えば、生計活動を中心とした多岐にわたる空間での活動を反映して、不思議な場所に関する伝承が生み出されたり、歴史認識の差異が空間認識の異なった伝承として記憶されることなどが挙げられる。さらにこれらの空間認識が、祭祀の構成を規定することによって、逆に空間に対する記憶を新たにしていく。一方、伊豆諸島の民俗的世界の組み立てを超越するような存在として、海からの来訪神をめぐる儀礼の存在を指摘することができる。これらは南西諸島に卓越した神霊観とは明かに異なっている。空間と儀礼の関係によって描き出される島世界の民俗的組み立ては、以上のように、伊豆諸島全般の民俗的対称性とともに、民俗文化間の「ずれ」をも示しているのである。
