Abstract. We present a building damage dataset following the 2024 Noto Peninsula Earthquake. The database was compiled from freely available, multi-source, remote sensing data, verified through opt-in crowd-sourced information. The dataset consists of geo-referenced vector polygons representing the pre-event building footprints of 140,208 structures. Each building was classified through visual inspection using pre-disaster and post disaster vertical, oblique, survey, and verifiable news reporting imagery. Entries were validated using voluntary-submission data sourced through a web-API hosting a live version of the database. We calculate classification metrics for a subset of the database where ground survey photographs were provided by independent surveyors. An average F1-score of 0.94 suggests that the proposed assessment is consistent and high quality. We aim to inform future disaster research such as disaster dynamics models; statistical and machine learning damage models; logistics and evacuation studies. The present work describes the data collection process, damage assessment methodology, and rationale; including limitations encountered, the crowd sourcing validation process, and the dataset structure.

Researchers with different academic backgrounds work together in disaster science. This qualitative study explores similarities and differences in the perceptions of values and measures of research outcomes in disaster science’s sub-disciplines. We also investigate how researchers trained initially in different study areas communicate, reflecting the state of Convergence Knowledge in disaster science. In this paper, 37 disaster science researchers in the sciences and humanities responded to an open-ended questionnaire survey. Regardless of their specialties, they evaluated an academic paper based on three main criteria: the researchers’ perception of the paper, the medium in which the paper was published, and the way it was used and read. They tended to value originality and the capacity to meet social needs. They pointed out matters in disaster science that should be acknowledged and the need for new indicators to assess them properly. However, attitudes toward numerical metrics and publication frequency differed by discipline. Also, there are few standard disaster science journals where they publish their successful papers, and the number of peers with whom they can interact professionally is limited. Therefore, the scope of academic understanding among disaster science researchers is limited, and its Convergence Knowledge has not yet been systematically advanced. However, mutual differences and the significance of interdisciplinary collaboration are recognized. Clarifying the benefits of interdisciplinary studies for researchers and launching appropriate indicators through cooperation among diverse sub-disciplines may advance Convergence Knowledge.

Abstract. With the rapid development of sensing platforms, unmanned aerial vehicle (UAV)-based mapping has become increasingly popular because of its economic efficiency and flexibility, especially for providing 3D information to support urban growth monitoring and change detection to meet sustainable development goals (SDGs). This paper presents an improved optical flow field-based dense matching algorithm (OFFDM) for low-altitude UAV images based on the Ph.D. thesis of Yuan (Yuan, 2018). First, high-precision seed points were used to compute the optical flow field within stereo pairs, effectively minimizing redundant calculations during the fine-matching phase. Second, a fine-matching approach, integrating multiple constraints, was applied to refine the coarse matching results based on the optical flow field. Extensive dense matching experiments on UAV low-altitude aerial imagery assessed the performance of OFFDIM across four dimensions: 3D point cloud visualization, matching success rate, precision, and reliability. Extensive experiments on low-altitude UAV imagery, characterized by a resolution of 7cm per pixel over a 10,608×8,608 pixel dimension and a 60% forward overlap, evaluate the OFFDM's efficacy. The quantitative evaluation revealed that the proposed method achieved an accuracy of ±0.7 pixels in image coordinates and ±20 cm on the ground, with a matching success rate exceeding 97%. The processing time was approximately 272 seconds for handling one single stereo pair. When compared to the widely adopted PMVS algorithm, known for its effectiveness in dense matching for UAV images, the proposed method demonstrated higher completeness and improved matching efficiency by more than five times. These results demonstrated that the proposed approach is more suitable for dense matching on UAV imagery-based high-precision 3D spatial data extraction, supporting global mapping tasks more effectively.

Tsunami evacuation towers play an important role in emergency evacuations in coastal regions. The placement of the evacuation towers has been determined based on the worst-case tsunami scenario. However, the tsunami intensity and corresponding arrival time to coastal regions should be estimated taking into consideration uncertainties associated with fault movements. It should be investigated whether the placements of evacuation towers based on the worst-case tsunami scenario can minimize the tsunami casualties. This paper presents a novel framework for optimizing the placement of evacuation towers based on the risk associated with tsunami casualties under the constraint of budget. As an illustrative example, the proposed method is applied to a coastal region affected by the anticipated Nankai Trough earthquake. The effect of the tsunami hazard assessment method on the optimal placement of evacuation towers is discussed.

Abstract 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.

In this investigation, we have conducted a long period teleseismic and tsunami waveform inversion to obtain the slip distribution of the 1974 Lima-Perú earthquake occurred in the central region of Peru. According to teleseismic inversion, the rupture process was complex with a duration of 90 s approximately and the main asperity was located in the northern side of the rupture geometry, offshore Lima and Callao. According to tsunami waveform inversion the main asperity was located in the southern side of the fault plane, offshore Cañete. However, a joint inversion of teleseismic and tsunami waveforms averaged the contribution of the two datasets and could give a better result. The maximum slip from the joint inversion was 7.25 m, and the moment magnitude was Mw 8.1. Despite the occurrence of this earthquake (almost 50 years ago), there is a high seismic potential to trigger a tsunamigenic earthquake in the central region of Peru. According to the interseismic coupling the next earthquake in the central region of Peru is ready to occur and it would be of 8.5–8.8 Mw.

Abstract Tsunami fragility functions (TFF) are statistical models that relate a tsunami intensity measure to a given building damage state, expressed as cumulative probability. Advances in computational and data retrieval speeds, coupled with novel deep learning applications to disaster science, have shifted research focus away from statistical estimators. TFFs offer a “disaster signature” with comparative value, though these models are seldom applied to generate damage estimates. With applicability in mind, we challenge this notion and investigate a portion of TFF literature, selecting three TFFs and two application methodologies to generate a building damage estimation baseline. Further, we propose a simple machine learning method, trained on physical parameters inspired by, but expanded beyond, TFF intensity measures. We test these three methods on the 2011 Ishinomaki dataset after the Great East Japan Earthquake and Tsunami in both binary and multi-class cases. We explore: (1) the quality of building damage estimation using TFF application methods; (2) whether TFF can generalize to out-of-domain building damage datasets; (3) a novel machine learning approach to perform the same task. Our findings suggest that: both TFF methods and our model have the potential to achieve good binary results; TFF methods struggle with multiple classes and out-of-domain tasks, while our proposed method appears to generalize better.

When a large-scale flood disaster occurs, it is important to identify the flood areas in a short time in order to effectively support the affected areas afterwards. Synthetic Aperture Radar (SAR) is promising for flood detection. A number of change detection methods have been proposed to detect flooded areas with pre- and post-event SAR data. However, it remains difficult to detect flooded areas in built-up areas due to the complicated scattering of microwaves. To solve this issue, in this paper we propose the idea of analyzing the local changes in pre- and post-event SAR data as well as the larger-scale changes, which may improve accuracy for detecting floods in built-up areas. Therefore, we aimed at evaluating the effectiveness of multi-scale SAR analysis for flood detection in built-up areas using ALOS-2/PALSAR-2 data. First, several features were determined by calculating standard deviation images, difference images, and correlation coefficient images with several sizes of kernels. Then, segmentation on both small and large scales was applied to the correlation coefficient image and calculated explanatory variables with the features at each segment. Finally, machine learning models were tested for their flood detection performance in built-up areas by comparing a small-scale approach and multi-scale approach. Ten-fold cross-validation was used to validate the model, showing that highest accuracy was offered by the AdaBoost model, which improved the F1 Score from 0.89 in the small-scale analysis to 0.98 in the multi-scale analysis. The main contribution of this manuscript is that, from our results, it can be inferred that multi-scale analysis shows better performance in the quantitative detection of floods in built-up areas.

In this study, the population change in sandy beaches across Japan were analyzed using hourly mobile network data for four years from 2019 to 2022 to obtain the characteristics of change in number of visitors to beaches. From the temporal changes in the monthly averages of the population in sandy beach meshes, the influence of seasonal changes and Covid-19 in the trend and fluctuations were different depending on the beach type. There are sandy beaches people comes from all over Japan and the same municipality. On the other hand, it is become clear that the lack of data due to restrictions on the available data concerning the protection of personal information makes difficult to obtain the actual population in places where the number of visitors is small.

In large-scale disasters, such as earthquakes and tsunamis, quick and sufficient transportation of emergency relief supplies is required. Logistics activities conducted to quickly provide appropriate aid supplies (relief goods) to people affected by disasters are known as humanitarian logistics (HL), and play an important role in terms of saving the lives of those affected. In the previous last-mile distribution of HL, supplies are transported by trucks and helicopters, but these transport methods are sometimes not feasible. Therefore, the use of unmanned aerial vehicles (UAVs) to transport supplies is attracting attention due to their convenience regardless of the disaster conditions. However, existing transportation planning that utilizes UAVs may not meet some of the requirements for post-disaster transport of supplies. Equitable distribution of supplies among affected shelters is particularly important in a crisis situation, but it has not been a major consideration in the logistics of UAVs in the existing study. Therefore, this study proposes transportation planning by introducing three crucial performance metrics: (1) the rapidity of supplies, (2) the urgency of supplies, and (3) the equity of supply amounts. We formulated the routing problem of UAVs as the multi-objective, multi-trip, multi-item, and multi-UAV problem, and optimize the problem with Q-learning (QL), one of the reinforcement learning methods. We performed reinforcement learning for multiple cases with different rewards and quantitatively evaluated the transportation of each countermeasure by comparing them. The results suggest that the model improved the stability of the supply of emergency relief supplies to all evacuation centers when compared to other models.

This study presents a method of real-time tsunami risk evaluation by combined use of proper orthogonal decomposition (POD) and Bayesian update. The validity of the proposed method is demonstrated through the numerical example targeting plausible tsunamis induced by Nankai-Trough events. First, tsunami simulations are carried out for plausible tsunami scenarios determined by various patterns of fault rupture, and the time histories of wave heights are stored at selected synthetic gauge points. Then, POD is applied to the resulting data matrix of the synthetic dynamics (SD) composed of dynamics modes and coefficients, the latter of which represent scenario-specific information. In the real-time risk evaluation phase, the wave sequences of an actual tsunami event are sequentially measured at the synthetic gauge points and used to estimate the corresponding dynamics coefficients of the constructed SD. At the same time, by the application of Bayesian update, the likelihood of each of the dynamics coefficients pre-calculated for the selected tsunami scenarios is evaluated at each time and sequentially updated to detect the most probable scenario. Finally, the pre-calculated tsunami arrival time and inundation depth distribution corresponding to the detected scenario are determined as risk assessment indices seven minutes after the tsunami generation.

The 2011 Great East Japan Earthquake caused massive devastation and numerous affected people. In particular, the Ishinomaki area of the Miyagi Prefecture was one of the hardest hit areas during the event. In addition, due to tsunami inundation, several medical facilities were destroyed or inactive at the time. The Ishinomaki Red Cross Hospital served as the last bastion to respond and attend injuries and illnesses in the disaster. We aim to build an agent-based model of triage and transportation of patients to the hospital. The individual and joint activities of response teams were considered to build the agent architecture and they were incorporated into the model. We model the first three days of response activities within the central Ishinomaki area and evaluated the number of patients transported to the hospital including their evaluated health status. We discuss here the case closest to the 2011 event and evaluate the strategies for search and rescue and patient transportation to speed up medical response in the aftermath of a disaster.

The goal of the Scientific Session: “Advances of International Collaboration on M9 Disaster Science” at the 2nd World Bosai Forum (WBF) in Sendai in November 2019 was to share progress on research projects and findings related to an M9 mega-disaster event, building on outcomes from a March 2019 collaborative workshop on M9 disaster science between research partners from the International Research Institute of Disaster Science (IRIDeS)/Tohoku University, University of Washington-Seattle (UW), and the Research Center for Integrated Disaster Risk Management (CIGIDEN). This paper reports on the presentations during the WBF Scientific Session, which shared updates and outputs of research collaborations from different disciplines, following the themes of risk-based planning, structural engineering, tsunami observation and early warning, and tsunami simulation and probabilistic tsunami risk assessment. This international and cross-disciplinary collaboration has led to the advancement of a number of specific research projects in different fields, as well as a robust network of researchers in the three countries. Based in coastal regions facing similar risks of massive earthquakes and tsunami in Japan, the United States, and Chile, it is hoped that ongoing and future collaboration within this network will continue to advance knowledge of disaster science and international disaster risk reduction.

Earth Observation satellite imaging helps building diagnosis during a disaster. Several models are put forward on the xBD dataset, which can be divided into two levels: the building level and the pixel level. Models from two levels evolve into several versions that will be reviewed in this paper. There are four key challenges hindering researchers from moving forward on this task, and this paper tries to give technical solutions. First, metrics on different levels could not be compared directly. We put forward a fairer metric and give a method to convert between metrics of two levels. Secondly, drone images may be another important source, but drone data may have only a post-disaster image. This paper shows and compares methods of directly detecting and generating. Thirdly, the class imbalance is a typical feature of the xBD dataset and leads to a bad F1 score for minor damage and major damage. This paper provides four specific data resampling strategies, which are Main-Label Over-Sampling (MLOS), Discrimination After Cropping (DAC), Dilation of Area with Minority (DAM) and Synthetic Minority Over-Sampling Technique (SMOTE), as well as cost-sensitive re-weighting schemes. Fourthly, faster prediction meets the need for a real-time situation. This paper recommends three specific methods, feature-map subtraction, parameter sharing, and knowledge distillation. Finally, we developed our AI-driven Damage Diagnose Platform (ADDP). This paper introduces the structure of ADDP and technical details. Customized settings, interface preview, and upload and download satellite images are major services our platform provides.

With use of modern computing power, advanced sensor networks and information technologies, a project is underway to establish a new system of real-time tsunami inundation forecasting, damage estimation, mapping and robust information dissemination to enhance society's resilience in the aftermath of major tsunami disaster. The system consists of fusion of real-time crustal deformation monitoring/fault model estimation, high-performance real-time tsunami propagation/inundation modeling with Tohoku University's vector supercomputer SX-ACE, damage/loss estimation model, geo-informatics and information technologies. The results are disseminated as mapping products to responders and stakeholders, e.g. national and regional municipalities, to be utilized for their emergency/response activities. In 2014, the system is verified through the case studies of 2011 Tohoku event and potential earthquake scenarios along Nankai Trough with regard to its capability and robustness.

 A non-hydrostatic free surface numerical model is required to perform a tsunami inundation simulation. It is, however, difficult to carry out large-scale tsunami simulation because of the iterative calculation of the Poisson equation in the invompressible flow model.  In recent years, the Lattice Boltzmann Method (LBM) has attracted attention as a novel computational fluid dynamics to overcome the incompressible flow model problems. In this study, we developed a two-dimensional LBM for free surface simulation method based on Piecewise Linear Interface Reconstruction - Volume of Fluid (PLIC-VOF) method. The classical dam-break and reconstruction test is used to verify our approach enables to high accuracy free surface simulation compare to conventional LBM-VOF method.

 Applicability of a tsunami inundation model with the polygonally nested grid system and its MPI-parallelization to nation-wide tsunami forecast was examined in terms of accuracy and computational costs through tsunami simulation at multiple grid resolutions of 270, 90 and 30 m. The computation efficiency of the tsunami model, in which the configuration of the grid system is extended from rectangular to polygonal regions so that deployment of high-resolution grids is confined to coastal lowland, was further improved by about 14 %. This paper also proposes an automatic way of setting the polygonally nested grid system, and elucidates that it requires 140 Tflop/s supercomputer resources to complete tsunami inundation forecast for the entire coast of Japan at resolution of 30-meter grids within 10 minutes.

 Applicability of rapidly estimated fault models based on real-time GNSS to tsunami simulation was examined, in comparison to tsunami survey data in 2011 off the Pacific coast of Tohoku Earthquake. GNSS models could show acceptable reproducibility in terms of tsunami height along the Pacific coast except the ria coast in Sanriku where considerably high tsunami observed in 2011. Tsunami inundation for lowland was fairly modeled by GNSS models in the case of city areas facing the Ishinomaki Bay. We also proposed a new method for rapidly estimating initial tsunami height from a slip distribution model that consists of a number of triangular sub-faults through approximation to a set of rectangular sub-faults.

 In recent years, real-time tsunami inundation forecasting has been developed with the modern computing power and earthquake tsunami observation system. However, uncertainties in tsunami source model derived from fault model may cause underestimation of tsunami damage. To prevent it, from disaster management point of view, we aim to determine the worst tsunami scenario, using seismic information of Earthquake Early Warning (EEW) that can be obtained after the event triggered. The method was applied to 60 cases of a hypothetical-earthquake, and verified that the method can effectively search the maximum tsunami height that may be happened as the worst tsunami scenario in 3 minutes.

 Lattice Boltzmann Method (LBM) is the one of the new and efficient Computational Fluid Dynamics (CFD) solvers. It has become an alternative powerful method compared with the other conventional CFD solvers. In the current study, we developed a robust tsunami simulation model by applying enhanced LBM for shallow water equations with treatments of the bed slope in the external force term in the Lattice Boltzmann equation.  The proposed model is verified by the comparison with the conventional tsunami numerical model which is based on the Finite Difference Method (FDM). As a result, LBM results are in good agreement with the FDM results. The results imply that LBM based on shallow water equations has sufficient applicability of tsunami propagation and inundation.

 Lattice Boltzmann Method (LBM) is the one of the efficient Computational Fluid Dynamics (CFD) solvers. It has become an alternative powerful method with the other conventional CFD solvers. In this study, we developed a free surface simulation model of LBM with the multiple relaxation time collision operator for high calculation accuracy. The model was verified in the still water simulation and the dambreak flow. The model results are in good agreement with the experimental data, including the movement of free surface of water and solid wall boundary condition. Through the model verification, we found that our model can be applied to simulate the complex behavior of free surface flows.

 This paper elucidated that it requires 2 Pflop/s supercomputer resources to complete tsunami inundation forecast for the entire coast of Japan at resolution of 10-meter grids within 10 minutes if we adopt a numerical model solving non-linear shallow water equations. Therefore, we improved efficiency of the model by extending the geometry of calculation regions from rectanglar to polygonal so that deployment of high-resolution grids is confined to coastal lowland, and validated its accuracy in comparison to the existing model. A wide-area tsunami simulation on the prefectural scale resulted in over 3 times more efficient, and the possibility of nation-wide tsunami inundation forecast was indicated.

 Detection of coastal damage due to the 2011 tsunami at Yamamoto Coast was attempted by the state-of-art remote sensing technology using ALOS PRISM satellite images. The digital surface model (DSM) was generated semi-automatically using the remote sensing software EADAS IMAGINE and its accuracy was confirmed by comparing with the digital elevation model (DEM) generated by aerial laser measurement. The coastal damage detected by residual of DSMs before and after the tsunami was verified statistically for each landuse of residential district, rice field, coastal forest, and beach. It was difficult to detect the damage in the low land area where ground objects were scarce; however, it was possible to detect the damage of the coastal forest and residential district. Furthermore, the erosion around seawall could be detected using the DEM instead of the DSM before the tsunami since the former has higher accuracy than the latter.

Tsunami fragility curves represent the relationship between the structural damage probability and the hydrodynamic features of tsunami inundation flow. In previous studies, a lot of tsunami fragility curves have been developed for tsunami affected areas. However, the characterization of tsunami fragility curves are not well disussed. In this study, using principal component analysis, 6 factors are obtained to classify 19 bays in terms of topographic features of bays, structure and distribution of building, coastal protection facilities, ground elevation and slope. As a result of classification by cluster analysis, the tsunami fragility curves from the 2011 Tohoku event were classified into 6 types according to regional characteristics.

Lattice Boltzmann Method (LBM) has been developed as a new, robust and efficient model to solve the fluid dynamics. In this study, we stabilize LBM on free surface flows applying incompressible model which is simple low cost. The model was verified in the dam-break flow experiment over a 3-D isolated block. The model results are in good agreement with the experimental data, including the movement of free surface of water body, and splash against the block. Through the model verification, we found that our model can be applied to simulate three dimensional behavior of tsunami inland penetration.

In the Tohoku-Pacific Ocean Earthquake, many bridges were washed away by the tsunami, the wave height of which exceeded the conventional assumption. In the future, countermeasure for tsunami disaster will be needed, and the evaluation of tsunami wave force acting on bridges will be very important. In this study, hydraulic model experiments and numerical analyses using VOF method were carried out for a bridge superstructure model to clarify the influence of tsunami wave shapes to tsunami wave force acting on it. As a result, it was confirmed that maximum wave force can be expressed as a function of the wave front slope of tsunami incident wave.

In this study, to clarify properties that tsunami wave force affect bridge superstructure which is generally applied to expressway bridges, waterway experiments and numerical analyses were conducted. In the waterway experiment, some tsunami waves which have maximum 10m height and 6.4m/sec water flow speed in actual scale were generated and characteristics of tsunami wave force acting on standard box-girder bridge were clarified. In the numerical analysis, to reproduce and evaluate results of waterway experiments, CFD (Computational Fluid Dynamics) with VOF method were carried out and applicability of this analysis method was confirmed.

Tsunami flow velocity on land is important for estimating tsunami load on structures. Numerical simulation is widely used to estimate tsunami load with flow velocity estimation. However, the simulation results have not been validated sufficiently because of the lack of observed information. In this study, through several case studies incorporating different initial and boundary conditions, authors simulated the 2011 Tohoku tsunami to discuss its verification with particular regard to tsunami inundation velocities. To better simulate tsunami inundation velocities, authors developed the tsunami run-up model with time-dependent building destruction model.

A semi-automated tool for detecting tsunami flooded areas is developed using high-resolution Synthetic Aperture Radar data (TerraSAR-X) focusing on the 2011 Tohoku earthquake tsunami event. A number of flood detection techniques proposed in previous studies have not been fully utilized for emergency responses due to their complicated procedures for image processing. Therefore,this study aimed at solving this problem by developing a semi-automated tool to detect flooded areas with a simple interface. The model was applied to Sendai plain and demonstrated a good performance showing producer's accuracy of 94.2 % and user's accuracy of 93.8 %.

An object-oriented method to detect building damage is developed using high-resolution synthetic aperture radar(TerraSAR-X) data focusing on the 2011 Tohoku earthquake and tsunami event. To detect changes caused by the tsunami,damage function was developed by correlating mean value of correlation coefficient calculated based on an object-oriented method using pre- and post-event TerraSAR-X data and building damage ratio in each object. The estimated result of damage ratio showed good agreement with ground truth data,showing the pearson's correlation coefficient of 0.96. The method was verified by applying on the other test site,and the results were found consistent with the reported damage features,with correlation coefficient of 0.8.

A rapid damage mapping with remote sensing and geoinformatics is essential for effective disaster response and recovery efforts. Among the remote sensorsSynthetic Aperture Radar (SAR) is remarkable for its capability to observe the Earth's surface regardless of wheather conditioins. In this paperin order to acquire the mea- sure of building damage level in the tsunami-affected areasthe authors analyzed a set of pre- and post-event TerraSAR-X intensity images. Focusing on the difference (d) and correlation coefficient (r) between backscat- tering coefficients of pre- and post-event images yields good estimation of structural damage with a form of discriminant regression function of d and r, with the accuracy of more than 70 %.

The Tohoku earthquake on March 11, 2011, which occurred off the Pacific coast of the northeastern (Tohoku) Japan, caused gigantic tsunamis and brought vast devastation and a huge number of human casualties. Various high-resolution satellites quickly captured the details of affected areas, and were used for emergency response. In this study, the extraction of tsunami inundation areas and damaged buildings were carried out using high resolution pre- and post-event synthetic aperture radar (SAR) images. Since the water surface generally shows very low backscattering intensity, the inundation areas could be extracted by the difference of SAR backscattered intensity between the pre- and post-event images obtained by TerraSAR-X. Then, the changed buildings were detected by calculating the difference and correlation coefficient in the shape of a building. When a changed building was enclosed by the inundation areas, this building was labeled as a damaged building by tsunami. Finally, the results were compared with visual interoperation results to examine the accuracy of the proposed method.

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.

A project is under way to search tsunami-affected area using recent advances of remote sensing technologies combined with a numerical modeling of tsunami propagation/inundation. In the present study, the authors propose a framework in developing a method to search and detect the impact of tsunami disaster by integrating numerical modeling, remote sensing, and GIS. Part of the method is implemented to recent tsunami events including the 2009 tsunami in American Samoa and the 2010 Chilean earthquake tsunami to search the tsunami-affected area and detect the structural damage, using the numerical modeling and the analysis of satellite images.

Tsunami has caused devastating damage to coastal regions many times. Since a period of earthquake occurrence generating tsunami can be estimated from historical records, the time of the earthquake occurrence and its magnitude are roughly estimated. Therefore, accumulation of field survey data and knowledge is important to prepare for future tsunamis. In this paper, we examined a simplified chemical analysis of soil to detect the tsunami inundation area and presented an on-site analytical method for inundation area detection. This chemical analysis is expected to support field surveys on tsunami inundation area.

&nbsp;A severe earthquake of Mw 8.8 occurred on 27 Feb. 2010 at Chil and the subsequent tsunami attacked the coast. The field survey was conducted in Chile to develop a new survey method based on a chemical analysis of soil. The soil samples were obtained from both the inundated and the not-inundated area and the content of water-soluble ions, electric conductivity (EC), and pH were measured. The tsunami inundated soil contains much water-soluble ions and the discriminant analysis of the tsunami inundation using the amount of ions in the soil showed high discriminant accuracy (over 90%) with Na+, Mg2+, Cl-,Br-, SO42-, and EC.

In the near future, it is estimated that the TouNankai and Nankai huge earthquake will occurs along the Nankai Trough. The earthquake generates tsunami attack over a wide range such as Seto Inland Sea where is dotted with islets and so many ships are navigating. In addition that many ships evacuate from port areas to safe area when the tsunami attacks. Sea traffic congestion is concerned about in such the evacuation.In this study, first, we analyzed the traffic density in Bisan Seto on the basis of AIS received data. Then we carried out several kinds of preliminary simulation of ship evacuation from tsunami attack in Bisan Seto for the purpose of consideration of evacuation scenarios. An algorithm of collision avoidance by reducing propeller rotation was introduced to the ships evacuation simulation.Finally, it is found that many ships can evacuate to safer place on time when the tsunami attack in Seto inland sea in safe.

We develop a hybrid 2D-3D simulation of Lattice Boltzmann Method (LBM) that increases the capability of simulating offshore/nearshore tsunami propagation and coastal inundation. For that purpose, the following schemes are newly developed to reproduce the free-surface movement of inundation flow including water splash in front of the structure, and nesting schemes of 2D/3D model for more efficient simulation of wave propagation and inundation in wider area. The model is validated by laboratory experiments of dam break and bore propagation.

In the past years, the Lattice Boltzmann Method (LBM) has been developed and applied to simulate single phase flow with a free surface. In this paper, the free-surface tracking algorithms are newly implemented in a multi-phase LBM model to expand a capability of LBM to simulate a complex behavior of fluid flow. The model was verified by standard dam-break (single-phase) and oil-slick (two-phase) experiments and were found to be in good agreement with the results.

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.

Not only hydrodynamic forces of tsunami current cause serious damage, but also driftage by tsunami may cause additional damage in a port and harbor area. Especially, in the 2004 Indian Ocean Tsunami, many stranded ships were observed. Therefore, when considering disaster prevention, the identification of expansion mechanisms of tsunami damage caused by drifted ships is very important. This study aims to develop a practical model to analyze the ship drifting and grounding motion by tsunami current. The simulated ship locus was consistent with the evidenced ship locus. And, as a hazard map, the potential damage due to ship drifting was evaluated by incorporating the possibility of collision with drifted ship.

This research aims to discuss a possibility of tsunami early warning system with the observation of hydro-acoustic waves (T-phase) caused by sudden sea-bed disturbance by a fault rupture. The authors derived an analytical solution of sea surface disturbances of slightly compressible ocean when the limited width of sea bottom is uplifted on a uniform slope to push up overlying water with the speed of V₀ and within the time duration of τ. Based on the analytical solutions obtained, we discuss the relationships between T-phase characteristics and the seismic parameters of rupture width, rise time and rupture velocity.

A field survey of the 2009 Samoa earthquake tsunami was conducted on Tutuila Island, American Samoa, within a week of the event. At the western end of the island, the largest runup height was measured to be 16.3 m and almost all buildings were completely destroyed and/or washed away. In the east, runup or inundation heights were smaller (2-6 m), but buildings were severely damaged. At Pago Pago, main town of the island, inundation heights were around 4.5 m, and inundation limit is about 600 m from the coastline. The tsunami arrived 5-10 minutes after the mainshock. The death toll was low, because federal and territorial governments had together carried out an extensive public education program to explain tsunami hazard.

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.

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.

The Lattice Boltzmann Method (LBM) has been developed as a new and robust numerical model to solve the fluid dynamics. In this study, we applied LBM for free surface flow, which Shallow-water approximation cannot provide accurate estimation. LBM was tested in some benchmark problems and laboratory experiment. The model results are in good agreement with dam-break experiment, including the movement of free surface of water body, splash against the upper wall, and a wave traveling back to the other side of the tank. Through the model validation, we found that LBM can be applied to simulate the complex behavior in tsunami wave front.

Hydrodynamic forces of tsunami current may cause additional damage by drifting ships or vessels in a harbor area. This study focuses on the damage mechanisms of drifted large ship, and aims to develop a model to analyze the large ship drifting motion by tsunami current. The model is implemented to Banda Aceh, Indonesia, to simulate the drift of a 2500-ton power plant barge of 63m-long which was drifted approximately 2.4 km inland by the 2004 Indian Ocean tsunami. In the model, the ship started drifting by the first wave, toward several kilometers inland from the original position. We found that the simulated grounding position was consistent with the evidenced position in the middle of Banda Aceh city.

Hydrodynamic forces of tsunami current may cause additional damage by drifting ships in a harbor area. This study focuses on the damage mechanisms of drifted large ship, and aims to develop a model to analyze the large ship drifting motion by tsunami current. The model is implemented to Banda Aceh, Indonesia, to simulate the drift of the power plant barge which was drifted approximately 2.4km inland by the 2004 Indian Ocean tsunami. In the model, we found that the simulated grounding position was consistent with the evidenced position.

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.

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.

The authors assess the capability of multi-purpose buoy system for tsunami warning, by calculating the number of potential tsunami casualty. The method is developed by integration of tsunami numerical models and GIS analysis with population database and fragility functions. The present method is applied to the potential tsunami events along the Sunda megathrust to assess the effect of tsunami casualty mitigation by implementing international/regional tsunami observation network of multi-purpose buoy system. The results imply that the international tsunami observation network can contribute to reduce the tsunami casualty along the Indian Ocean countries up to 60% by expecting the lead time to issue the early warning.

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.

Disaster mitigation management is considered a very important aspect in marine catastrophes, such as a tsunami, especially because drifting ships containing passengers and hazardous substances can cause a huge disaster in a port. It has already been analyzed that at the arrival of a tsunami, it is very hazardous for a large passenger vessel to evacuate passengers first. In this study, the assessment of evacuation at Osaka Bay in Japan is based on Automatic Identification System (AIS) data used as input for a Discrete Event Simulation (DES), which assesses ship evacuation time and using the Geographic Information System (GIS) to determine the locus of ships. The location of ship evacuation is decided in the anchorage area since the time needed for a ship to evacuate outside Osaka Bay is more than the predicted time of a tsunami arrival. In this paper, a preliminary proposed safe area for evacuation is evaluated and the possibility of large passenger vessel evacuation is shown.

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).

The fishing boat damage and its reduction plan are discussed in the present study through developing hazard maps in the sea. Although the countermeasures on the land against the tsunami attack have been developed by constructing sea walls and creating hazard maps, but one in the sea is less at the present. The evacuation flow for fishing boat is discussed by the process of issuing warning and making decision and action, depending on the location of occurrence of tsunami and that time. A hazard map on the sea could be made by adding the information of tsunami arrival time, maximum water level and velocity and boat damage index developed in the present study.

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.

It is concerned about the occurrence of huge earthquake on Nankai Trugh off the coast of Shikoku such as Tokai, Tou-Nankai and Nankai earthquake. Tsunami attack by the earthquake will generate not only the raise of sea surface but strong horizontal current in the Osaka bay. There are some manuals for ship evacuation which describe only that ship in harbor should leave the port immediately. Moreover there are so many ships that are navigating and moving. Therefore, it is very important for marine disaster prevention to upgrade the manual of ship evacuation in tsunami attack. We carried out several kinks of preliminary simulation of ship evacuation from tsunami attack in Osaka bay for the purpose of contribution to the improvement of such manuals under the background. The results show that it is difficult for every ship to evacuate to outside of Osaka bay through Tomogashima channel and Akashi straits. But it is possible to evacuate to nearest anchorage zone of each port. The manual will be improved by piling such examinations as evacuation simulation

Using a GIS database and numerical modeling technique, the author developed a method of obtaining a quick estimate of the impact of a great tsunami disaster. The estimates can pinpoint the area where more precise damage detection technologies such as high-resolution satellite imagery or other remote sensing data should be deployed, to maximize a limited amount of time and resources. During the 2004 Indian Ocean tsunami disaster, we spent a great deal of time comprehending the overall damage within the entire Indian Ocean. The present research strongly suggests that research communities from various fields should collaborate to enhance the capability of quick and effective post-tsunami disaster response to the next possible tsunami disaster.

We are concerned about the occurrence of Tokai, Tonankai and Nankai earthquakes in Nankai Trough located at southern Japan sea area. The possibility of the occurrence is estimated as over 50 percent in these 30 years as of January, 2005. The tsunami by the earthquake attacks to the coastal area of Japan and generates not only the raise of sea surface but strong horizontal flow. The ships in the bay are forced to move by the current and such unexpected phenomena may occur as the addition of large force to a pier, uncontrollable lateral motion, collision to breakwater and drifting and grounding. It is very important to grasp the drifting motion of the vessel caused by tsunami current and make action guidelines against the attack for the prevention of sea disaster because such accidents bring serious results especially in the ports where dangerous cargoes are unloaded and loaded. From such viewpoints, basic analyses for ship evacuation maneuver from the tsunami attack were carried out and effectiveness of the action was shown.

A questionnaire survey was undertaken for residents' evacuation against tsunami attack and factors of their decision-making on the earthquake of Miyagiken-Oki which occurred on May 26, 2003 and it was carried out in Kesennuma City, Miyagi Pref.. As the result of the survey, it turned out that almost all residents were afraid of tsunami attack, but they did not evacuate. Then we analyzed residents' evacuation and their consciousness of tsunami. The main problems of residents' consciousness of tsunami cleard by the analysis are follows. 1) Since residents depend for decision-making of evacuation on evacuation order and tsunami warning, they cannot make decisions evacuation even if they feel a big shake. 2) By the normalcy bias, residents estimate the danger level of tsunami optimistically. 3) Residents' tsunami experience has influenced with their tsunami image strongly. 4) However residents depend on tsunami information, they tend to make light of them. In this paper, we discussed what education the tsunami prevention should be for improving those problems.

We are anxious about the occurrence of Tokai, To-Nankai and Nankai earthquake. Tsunami attack generates not only the raise of sea surface but strong horizontal current in the bay It is very important for marine disaster prevention to grasp the drifting motion of a vessel caused by the tsunami curent. From such viewpoints, a basic analysis method for ship drifting phenomena by tsunami attack was developed. According to the ship drifting simulation by tsunami at the bay of Owase, Mie Prefecture, we found a possibility that a vessel collides with a berth, and also a possibility of ship grounding by the tsunami current. Such results suggest that still more detailed examination is required in the future.

This paper presents the fragility function for wooden house obtained from the field investigation of the flood disaster in Nakanoshima town, Niigata prefecture due to the July 13, 2004 Niigata heavy rainfall. At the emergency phase of disasters, the early understanding of overview of damage is required for the management of emergency personnel and resource. To understand the overview of damage easily, fragility function which estimates damage from inundation depth is helpful. The inundation depth is measured at many points and the damage rank of each house is identified in the investigation of this disaster. The fragility function is constructed using these data. Additionally, we marshaled those data about building damage and reviewed documents about damages in past tsunami disaster. By comparing obtained data to fragility curve, we considered the influence of driftage on building damage and the adequacy of that curve.

Metropolitan areas and coastal communities along the Pacific coast and the Inland Sea in Japan are under the threat of gigantic tsunamis accompanied with possible megathrust earthquakes along the Nankai Trough within 30 to 40 years. The authors propose a cooperative network for tsunami disaster management, that consists of the integrated system of real-time tsunami modeling techniques and real-time tsunami observation system. This system will be in public at "http://trust.dri.ne.jp/".

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.

The author derives 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.

A number of people were killed caused by the 2011 Tohoku (Great East-Japan) Earthquake and its induced Tsunami. Evacuation before the arrival of Tsunami is important to survive, however, it might be sometimes difficult for the people who are in a coastal area to escape. To overcome this situation, self-floating evacuation facility has been proposed by Meguro(2011). In this study,two-dimensional spatial distribution of fluid force in Kochi area is analyzed assuming the Nankai Trough massive earthquake and Tsunami. First, Tsunami numerical modeling was conducted and the distribution of hydrodynamic force was calculated. Next, the force that acts on the self-floating evacuation facility was estimated by using the result of Tsunami numerical modeling. As the result, a maximum force acting on the facility was calculated as about 2,530 kN.

The grasping damage by SAR is suited to large scaled disaster such as an earthquake and tsunami. Especially, L-band SAR data can observe extensive areas at once. To analyze building damage caused by the 2011 Tohoku earthquake and tsunami disaster, we applied a method to divide target area into rectangular analyzed areas for the evaluation of building damage. A number of method for estimating building damage at a rectangular tile scale have been proposed, however a suitable size of the tile has not been identified. Therefore, this study aims to examine the effective size for damage estimation by clarifying the relation between the number of buildings in the analyzed area.

&nbsp;An object-oriented method to estimate building damage is developed using Advanced Land Observing Satellite/Phased Array Type L-band Synthetic Aperture Radar (PALSAR) data from Japan Aerospace Agency (JAXA), by focusing on the 2011 Tohoku earthquake and tsunami event. The building damage was estimated by applying the developed damage function showing a relationship between the correlation coefficient values of pre- and post-event SAR data and the damage ratio of washed-away buildings. The result was verified by the actual number of washed-away buildings, and offered the good accuracy with pearson's correlation coefficient of 0.97.

A semi-automated tool for detecting tsunami flooded areas is developed using high-resolution Synthetic Aperture Radar data (TerraSAR-X) focusing on the 2011 Tohoku earthquake tsunami event. A number of flood detection techniques proposed in previous studies have not been fully utilized for emergency responses due to their complicated procedures for image processing. Therefore,this study aimed at solving this problem by developing a semi-automated tool to detect flooded areas with a simple interface. The model was applied to Sendai plain and demonstrated a good performance showing producer's accuracy of 94.2 % and user's accuracy of 93.8 %.

An object-oriented method to detect building damage is developed using high-resolution synthetic aperture radar(TerraSAR-X) data focusing on the 2011 Tohoku earthquake and tsunami event. To detect changes caused by the tsunami,damage function was developed by correlating mean value of correlation coefficient calculated based on an object-oriented method using pre- and post-event TerraSAR-X data and building damage ratio in each object. The estimated result of damage ratio showed good agreement with ground truth data,showing the pearson's correlation coefficient of 0.96. The method was verified by applying on the other test site,and the results were found consistent with the reported damage features,with correlation coefficient of 0.8.

Super Typhoon Haiyan that struck the Philippines on November 8, 2013 caused over 7,000 casualties by remarkably high wind speed, storm surges and waves. In this paper, characteristics of human loss in the coastal region of Leyte Island, Philippines were investigated based on the relationship between the observed inundation height and depth and the number of deaths and missing people in each barangay. From the analysis, barangays with more than 10 % of the fatality ratio were found along the coastal areas in Tacloban city and Palo and Tanauan municipalities. It was found that the scale of human damage caused by Haiyan is similar to that caused by any other historical tsunami disaster, clearly indicating the massive external force of the storm surge during the Haiyan event and the vulnerability of those coastal areas.

A method for rapid detection of tsunami devastated areas using multi-temporal TerraSAR-X data is proposed. To develop the method, machine learning algorithm, a branch of artificial intelligence (AI), is applied. We focus on the multiple bounce reflection which is a specific feature on Synthetic Aperture Radar (SAR) data to estimate building devastated areas. Finally, classifiers which enable automated classifications of damage patterns into predicted damage classes were built. The evaluation of the model was conducted through cross-validation and the best accuracy was obtained as 89.2 %.

This study aims to identify the structural vulnerability against tsunami with the form of tsunami fragility curves by integrating structural damage mapping with field survey data,such as flow depths. The tsunami fragility curves are preliminary obtained from the case studies in the affected areas of the 2011 Tohoku earthquake tsunami. Consequently, we found that structures in Miyagi Prefecture were especially vulnerable when the local flow depth exceeded 2 m, and 6 m flow depth would cause total devastation. Through the analysis, the tsunami fragility curves were obtained for each coastal community to determine the structural vulnerability against the local tsunami heights.

The authors propose a research framework in developing a method to search and detect the impact of catastrophic tsunami disaster by integrating remote sensing and GIS technologies, which consist of four damage mapping efforts, 1) Inundation mapping by satellite remote sensing, 2) Structural damage mapping by aerial photo interpretation, 3) Estimation of structural damage, 4) Mapping tsunami debris by post-event image analysis as an indicator of impact. The method is implemented to the 2011 Tohoku earthquake tsunami disaster to identify the regional impact of this event.

The Lattice Boltzmann Method (LBM) has been developed as a new and promising numerical model to solve the fluid dynamics. In the present study, the applicability of LBM for the Shallow Water Equations is discussed in terms of several problems. LBM is appliable to flow around pillars and its solution is well agreed with experimental data. LBM can be applied to the tsunami run-up problems, and its solution has the accuracy as same as that of the Finite Difference Method in the same spatial resolution.

To simulate oil spreading into industrial coastal zone caused by tsunami inundation flow, we developed a 2-layer hydrodynamic model which considered interaction between tsunami and oil. In this paper, we studied the numerical methods of oil spread in a numerical water tank using a 2-layer model. Based on the result of the numerical simulation which obtained by changing the interfacial resistance coefficient, we discuss applicability of our model, focusing on the relation between the interfacial resistance acting on the bottom of the oil layer and advection distance of oil layer.
Effect of transmission performance on parallel processing source code for a tsunami numerical analysis

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.

The "disaster relief volunteer center" has been established as a new support system for disaster victim by volunteers. One of the most important issues to consider when running a disaster relief volunteer center is how to help people who have greater needs - the eldery and disabled, for instance. Those people may require more assistance than the government can provide. This paper examined the potentiality and the task of the new support system from the case study of the disaster relief volunteer center of Nakanoshima-cho established after the July 2004 Niigata heavy rain disaster. As a result, it turned out that investigation of the support demand by community based organizations worked effectively in the process of the adjustment of volunteers' supply and demand.

In usual, ports and harbors planning are conducted without considerations of tsunami because of its long return periods, such as over 100 years. However, recently it is warning that the Nankai and Tounankai Earthquake are anticipated to surely occur in 30 years. These earthquakes involve the large scaled tsunami. Thus the surrounding circumstances of port and harbor are changing, so we cannot ignore the tsunami that is neglected in the port and harbor planning until now. We must correspond to the warnmg.The counteimeasures will be wide and contain many kinds. In this papa; we consider the effect of the tsunami on ports, especially on moored ships at large scaled tsunami.

The purpose of this research project is to apply and expand the concept of “Digital Twins” to disaster science and build a “Disaster Digital Twin” (DDT) which utilizes human-centered data to improve community resilience. Specifically, the DDT and a multi-agent simulation framework developed by the Japanese team will be applied in a context of the elderly, a population with personalized care needs which is disproportionately affected by disasters. This will be done through the integration of the “CareDEX” by the U.S. team, a platform which incorporates personalized care information from responders, caregivers and the elderly, with a digital twin developed by the both teams. This integration of technology developed by the two teams is expected to enable a variety of “Virtual Disaster City” (VDC) simulations which will be useful for policy design in for the elderly with the specific needs, for example medical equipment, reduced mobility, cognitive disease, in a context of disaster resilience.

The project promoted collaborative research among science, engineering, and disaster medicine with the goal of enhancing resilience of disaster medical systems by integrating real-time simulation and sensing. Considering the catastrophic tsunami disaster concerned as future risks in Japan, we achieved three outcomes ; 1) quantitative and rapid estimation of human and physical damage caused by the tsunami, 2) immediate estimation of medical demands in disaster affected areas, and 3) methodology for planning and updating disaster medical activities through multi-agent simulation. Through the project, we examined the required specifications for an innovative medical support system in the anticipated disaster process of future Nankai Trough earthquake and tsunami disaster that is expected to occur next 30 years.

It was clarified by simulation that the coherence of PALSAR-2 images before and after the earthquake changed in the liquefaction area of the Kumamoto earthquake. It was also shown that a similar tendency was observed in the liquefaction area of the Hokkaido Iburi Tobu Earthquake. Then, the fragility function was constructed from the building damage data of the Kumamoto earthquake, and the relationship between the ground strain calculated from the SAR image and the gas pipeline damage was clarified. As an example of bridge monitoring, a long-term InSAR analysis from 2004 to 2017 was carried out using four satellite SAR images for a bridge over Lake Urmia, located in the northwestern part of Iran, and clarified the factors of bridge settlement.

Using a next-generation co-processor, we aim to develop a community tsunami inundation forecast system to be implemented in a community-level tsunami disaster response. To achieve tha goal, the research team conducted a research to optimize a tsunami inundation model running on a new computational platforms, to clarify the required computational resources, quality of the simulation, potential hardware configurations. As a result, we found that the TUNAMI code (Tohoku University's tsunami inundation simulation code) can be efficiently optimized on a new vector processor called SX-AuroraTSUBASA. It achieved a performance to execute the 6-hour inundation forecast with 10 m resolution in about 4 minutes using 256 cores. This research achievement leads to construct a community-based tsunami inundation forecast system for the end-users such as local municipality.

We developed an estimation model for calculating the water occupancy based on satellite SAR observation, comparing backscattering coefficients of the ALOS PALSAR image and the water fraction information derived from SMA method, which is applied to the Landsat-7 ETM+ reflectance image observing the 2011 Bangkok flood and the 2011 Tohoku earthquake tsunami. We performed the three-dimensional building damage models, created by applying the SfM-MVS technology to images taken by the aerial photographs of the site of the Hiroshima heavy rain disaster in 2014, a three-dimensional model was generated and we clarified the relationship between the spatial resolution and the accuracy of the aerial photographs by comparison with the LiDAR data. Furthermore, a three-dimensional model was created from the images taken before and after the Great Hanshin-Awaji earthquake, and the building damage was extracted from the altitude differences in the buildings measured in these two different periods.

When natural disasters strike, such as tsunamis and floods, people are sometimes left and they are isolated in disaster-affected areas. For searching those people more quickly, UAV (Unmanned Aerial Vehicle), which can be easily operated by remote control, is believed to have the capability. In order to make the search activity using UAV more reliable and efficient, methods for detecting survivors automatically are necessary. In this study, by applying several image analysis methods to the images taken with UAV, we tried detecting humans from those images with high accuracy. As a result, we succeeded to detect them with zero to eight misdetections and little nondetections by utilizing their whole bodies, upper bodies, shadows, and line segments in the images.

Tsunami submerged breakwater (TSB) is proposed as a new disaster mitigation hardware reflecting on serious damage by the 2011 Tohoku Tsunami. TSB can change directions of horizontal and vertical tsunami flows, and weaken tsunami power in coastal regions. At the beginning of the research, actual structures aiming for tsunami disaster were investigated about damage condition by the tsunami and weakening effect for the tsunami. Based on the investigation, a geometrical form of TSB was designed from the hydraulic engineering approach. The form was evaluated by the hydraulic experiment and the three-dimensional numerical modeling. And necessary conditions of TSB as a concrete structure to put into practice were examined.

A new tsunami observation system has been developed, which employs the GPS technology to detect a tsunami before it reaches the coast. After a series of preliminary experimental studies, the GPS buoy system is employed along the Pacific coast and Japan sea coast. Currently, the GPS buoy system uses RTK (Real Time Kinematic) method which requires land base for precise positioning of the buoy. This limits the distance of the buoy from the coast at most 20km. There are two problems to be conquered, one is the precise GPS positioning and the other is the data transmission methods. The algorithm of PVD (Point precise Variance Detection) method and PPP-AR (Precise Point Positioning with Ambiguity Resolution) method are successfully under examination in the Muroto GPS buoy. Also, the satellite communication system using QZSS (Quasi-Zenith Satellite System) and ETS-VIII (Engineering Test Satellite VIII) were introduced for this GPS tsunami observation system experimentally.

A tsunami attack on the coast would not only increase the sea level, but would also create strong horizontal flows in bays and ports. It is very important from the viewpoint of marine-disaster prevention to gain a better understanding of the motion of ships originating in tsunami flows and to develop countermeasures in the face of a tsunami attack. A new evaluation system of ships movement under the tsunami attack has been established by use of computer fluid dynamics method. As the results, it enables the simultaneous estimation of the movements and mooring forces exerted on moored ships in the case of a tsunami wave.

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 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.

In order to investigate the relationship between development and disaster reduction strategy in developing country, we take a look at the case of the basin of the Laoag River in Ilocos Norte Province, Phillipine. A concrete continuous high embankment is advantageous for Ilocos Norte Province and Laoag City in some respects: (1) the province and the city will become free from the flooding and inundation that happen every time a typhoon occurs, (2) it will become possible to develop the old river courses and flood sources without making an assumption that flooding will occur, and (3) structures not requiring frequent maintenance will compensate for the governmental low capabilities for maintenance. However, when unexpected external forces cause excessive floods, it is likely that the damage will be enormous because of development projects, or life may be underway without making an assumption that flooding will occur. Engineers in developed country must understand that non-structural measures include the following:1) Measure to maintain structures for a long period of time, 2) Measure to enhance residents' awareness of disaster prevention, 3) Measure for damage control, including the collection and transmission of weather information, the comprehension of dangerous areas, and evacuation advisories, 4) Measure for damage reduction, including relief activities. Aid will be able to fulfill some sort of role for all the measures. For that purpose, first of all, it is necessary to learn current and past governmental and residents' response to disasters. When we stayed in the Philippines, the typhoon broke an embankment, and some farmers' rice paddies were washed away. The immature technology of constructing the embankment was one of the reasons for the breakage. Aid providers must consider measures for structures to stay, including the acquisition and transfer of knowledge and technology necessary for the construction of structures, and compliance at the time of actual construction. For restoration and reconstruction activities, it is necessary to review governmental response, and find out how communities in particular can be involved with residents who had their rice paddies washed away, and lost the means of production. The above-mentioned communities include administrative villages, and organizations and networks that individuals belong to engineers on the aid-giving side need to plan types of structures that will stay in regions in consideration of non-structural measures. In order to do so, they should make efforts to understand the regions with the participation of experts and researchers who research into society. The task of understanding the history of regions, including the history of disaster prevention, will teach us many things. The task of understanding the history is to find out the following things, for instance, from the government and many residents: 1) How is the memory of such a disaster accumulated among residents, and shared in communities?, 2) What kinds of people were struck by the disaster?, 3) Did the past damage caused by flooding and inundation help enhance residents' awareness of disaster prevention?, 4) Did residents take any kinds of measures for disaster prevention, or did residents request anything from the government about disaster prevention?, 5) Who helped the livelihood of disaster-stricken persons? And 6) Did residents voluntarily provide labor for the repair and construction of structures?

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.
