    In this paper, we discuss a spreading frres in the Great East-Japan Earthquake. In the Great East-Japan Earthquake, many serious spreading fires happened in the Tohoku and Kanto district. According to the report of Fire and Disaster Management Agency, 284 fires happened in the Great East-Japan Earthquake. In Urban area on the Sanriku Coast, many large spreading fires were caused by Tsunami. We call it Tsunami Fire. Characteristics of these frres differ greatly among regions. Typical frres that occurred in the Sanriku coastal region arose from a lot of combustible materials, such as houses and vehicles, which were destroyed and swept away by the tsunami waves toward a mountain, caught fire from a source of frre (domestic and other various fuels) drifted there, and spread into town areas and forests. On the other hand, in plain areas where the population and industries were concentrated, a small number of fuels, such as household gas cylinders and vehicles scattered about the town, joined together into a mass of combustible materials, which are estirnated to have made a great contribution to potential outbreak or spread of fires. In any region, it is estimated that tsunami fires were caused by a combination of various potential factors such as an electric leakage, a short circuit, and sparks from a crash.

    After the great earthquake in Tokyo Metropolis, a lot of vehicles and pedestrians are expected on the road network because of the disruption of public transportation. Since the traffic is heavy, it will be difficult for emergency response vehicles to work efficiently. The objective of this study is to estimate the decrease of travel speed of emergency response vehicles after the great earthquake in Tokyo Metropolis comparing with that of general vehicles. To achieve the objective, the probe data derived from taxis and the records of emergency activities by Tokyo Gas Co., Ltd. are employed. The estimations of travel speed are implemented with respect to road types and local meshed units.

    Casualties in recent 66 Japanese earthquakes occurred from1999 to 2008 are surveyed and discussed. In 66 earthquakes, 11,921 casualties have been reported. We surveyed the circumstances where those casualties occurred. Publications by the central and local governments, and newspaper articles are collected. Information on casualties such as age, sex, place and cause are examined. As a result of the analysis, we confirmed chiefly the following points.Three major causes for deaths were shock or stress (47%), landslides (21%), and building collapse (18%). In contrast, the primary cause for serious injuries was slipping or stumbling (74%). For casualties, vulnerability of aged people was observed. The ratio of female of casualties was higher than that of male in elderly age group.

    In the 11 March 2011 Tohoku, Japan earthquake, widespread liquefaction occurred in Urayasu city, Chiba prefecture, and it caused serious damage to wood-frame houses, underground pipelines and other structures. In this kind of situation, it is effective to estimate damage distribution quickly for emergency response purposes. But early damage estimation of structures due to liquefaction is very difficult because these damages do not appear clearly on the ground surface. On the other hand, it is comparatively easy to access the degree of liquefaction using sand boils and ground subsidence, which can be observed from the ground or air. Thus in this study, the relationships between these visible effects due to liquefaction and various damage are investigated using aerial photographs.

    Information on post-earthquake serviceability of lifelines during the anticipated earthquakes is essential to enhance social preparedness and emergency management capabilities. In this paper, an assessment model for seismic damage and restoration process of electric power, water and city gas supply systems was applied to the case of the Great East Japan Earthquake Disaster. The original model, developed on the basis of the experiences of the Great Hanshin-Awaji Earthquake Disaster, was modified and combined with the population exposure to seismic intensities. The number of people without lifeline services and their restoration curves were evaluated and compared with the actual values. Good agreement was found and the assessment model was validated with appropriate parameters settings.

    The Great East Japan Earthquake, which occurred on March 11, 2011, generated a huge tsunami and caused devastating disaster in the coastal towns bordering the Pacific Ocean. To reduce tsunami disaster, the hazard map is one of the useful tools as guidance for evacuation for citizens. There are, however, problems in quality and quantity of information and representation on the map. The authors analyzed the problems on sign information of tsunami hazard map by reviewing the previous studies and the existing hazard maps, and proposed representation of sign information for better tsunami hazard map.

    Kobe City Waterworks (Kobe Water) was attacked by the 1995 Hanshin-Awaji Great Earthquake and supply had interrupted for three months in most damaged area. From these situations Kobe Water has recovered and turned to be an advanced redundant water system. In this process Kobe's restoration plan had an important role as a guideline of reconstruction works. In this paper the author describes the factors incorporated into this plan and the effects which achieved “resistibility" against an earthquake. At this point after 17 years from the 1995 EQ it can be pointed out some lessons leamed, which will be of use for the 2011 Higashi-Nihon Great Earthquake and forthcoming Nankai-Tonankai Earthquake.

    This paper presents an analysis of the building damage evaluation by tsunami on the 2011 Great East Japan earthquake. The building damage evaluations were carried out by the local governments for issuing the damage certificate. The uniform inspection guideline for the evaluation was developed by the cabinet office of Japan, however, many local governments modified it by themselves. As the result, the damage evaluation criterion of a local government does not correspond to others. This paper presents an analysis of such inspection resu1ts and proposes a modified procedure ofthe damage evaluation.

    This paper presents a method for network reliability improvement of the road network of Mianyang City after the 2008 Sichuan earthquake in China. In order to improve the network reliability of Mianyang traffic system, the damage of the traffic system in this earthquake and the problem on the traffic system is stated firstly. Secondly, the present condition of disaster prevention planning in China is introduced. Since it is very difficult to obtain the exact values for the set ofthe link reliability of Mianyang road network after this earthquake, an assumption for calculating link reliability is proposed. Based on this set of link reliability, road network reliability is improved using the Importance Analysis. At the sametime, cost-benefit analysis is calculated with two cost-reliability functions.

    Business continuity plan must be constructed in order to promote the restoration from the impact of the major disasters. Business impact analysis, which is conducted on the qualitative or quantitative data basis, is needed for assessing the feasibility of the plan. We proposed the spatial data assessment because resource management is the crucial issue for realizing the business continuity plan. Nippon Expressway Company Limited, one of designated public institutions, has the obligation of supporting disaster response operation of the road restorations. NEXCO constructed the proactive and active business continuity plan and tested those efficacies using business impact map.

    Recently, torrential downpours have happened frequently and caused damages in Japan. Japanese Meteorological Agency already has an observation system which covers each administrative boundary to provide the hazard information. However, it is impossible for us to know the risk coming "right here and right now" with this system. The purpose of this research is to develop “Micromedia”, an information system utilized GIS and location information, which provides all individuals in Japan with real-time disaster information anywhere, anytime by using mobile phones (smart phones) and car navigation systems with GPS.

    The Probabilistic Seismic Hazard Maps developed by the Headquarters for Earthquake Research Promotion indicate the possibility of strong shaking within 30 and 50 years at every location on the map. Recently, long-lived constructions are expected from the viewpoint of sustainability. The Architecture Institute of Japan proposes that the buildings are in use for 100 years. To achieve this, the earthquake risk for long-lived constructions should be evaluated. In this stuldy,the 100-year seismic hazard is quantified using the dataset compiled in the J-SHIS. The six sites, Sapporo, Sendai, Shinjuku, Matsumoto, Nagoya, and Fukuoka, were selected to show the characteristics of seismicity.

    The Great East Japan Earthquake hit eastern Japan on March 11th., 2011. It is called the textbook for the Tokai, the Tonankai and the Nankai Earthquake that are predicted to occur in the near future. In this quake many helicopters played their active role, but several issues appeared in operating them. These issues have remained from the Great Hanshin-Awaji Earthquake which was the first case to operate many relief helicopters, but there was no analysis and no assessment conceming them. In the case of three quakes occurring at the same time, so many helicopters would fly to the affected area according to the corresponding plan. In this paper, the author would like to analyze and propose a new system to better utilize relief helicopters.

    This study developed the method to assess wide-area logistics support base in the vicinity of impacted area that remarkably functioned after the Great East Japan Earthquake. We analyzed the spatial allocation of rescue organization headquarters and concluded substantial life service, less than 50km from impacted areas, accessible to multiple impacted areas, and large space facility as the required conditions. Addition to seismicity and tsunami by the Great Earthquakes along the Nankai Trough, these conditions are applied into Kii Peninsula and Shikoku area in a suitability analysis. It clearly identified 6 sets of wide-area logistics support bases,impacted areas, and unavailable areas. The method demonstrates location of wide-area logistics support base for wide area disaster management.

    After the March 11 Great East Japan Earthquake, people living in Japan were faced with confusing and conflicting messages from differing information sources which created an atmosphere of uncertainty and led many people, particularly foreigners, to relocate to western Japan or leave the country entirely. In order to improve the dissemination of information after future disasters, a survey was conducted to understand how foreigners in the Kanto region received their disaster-related information and how it affected their decisions in the aftermath of the disaster. Through the survey, it was found that the role of domestic information sources versus overseas information sources could have contributed to the confusion foreign respondents experienced and led to their relocation or evacuation from Japan.

    Breaking news of the "Great Earthquake in Japan" was spread all over the world just five minutes after the Great East Japan Earthquake struck on March 11, 2011. During the great flurry of information from both domestic and overseas sources, how did foreigners residing in Japan collect disaster-related information? On which information sources did they rely? Did the difference in language ability for Japanese and English have an influence on their information collection behavior? In order to answer these questions, we conducted a questionnaire survey of foreigners and Japanese who were residing in the Kanto region at the time the earthquake occurred. Five sample groups were created based on the respondents' language ability, and their disaster information collection behavior was analyzed. The results illustrate the channels of information dissemination among foreigners during the disaster, and measures for improving disaster information dissemination to foreigners were proposed.

    This study aims to clarify the existing system for coordination among local governments in a muliti-location disaster through the experience of the Great East Japan earthquake. In Japan, the Basic Disaster Act defines that the loss of municipal capacity would be supplemented through support from other municipalities, however, there is no effective coordination system in place. In the Great East Japan earthquake, municipalities along the pacific coast suffered severe human and physical losses. Prefectural governments tried to gather local needs and coordinate resources provided from other prefectural governments but it was difficult to match resources without an effective on-site mechanism for gathering and sharing information about needs and available resources.

    The Great Hanshin-Awaji Earthquake has taught us that municipality based-reliant activities alone are not effective and that inter-local-government-assistance is of paramount importance. Moreover the Great East Japan Ealihquake, which was a large-scale and wide-area disaster, reminded us of the importance of emergency support systems among local governments. The purpose of this study is to find solutions to the problems of the current local governments' emergency support system based on case study of Kobe city assistance to the affected municipality governments. The result emphasizes the importance of improving power to receive outside support in addition to improving power to provide support to ensure the promptness and effectiveness of inter-local-government-assistance.

    Numerous educational materials have been developed to raise public awareness on disasters. However it has been often the case that these materials are not seriously accepted by adults and have not lead to preventive action. To address this issue, we have developed a new program; "Ichi-Nichi-Mae Project" for Disaster A wareness. This program interviews people who have been seriously affected by a major disaster, by posing the question "What would you do if you were back the day before the disaster?", and edits the most impressive personal short stories which gives clues for future preventive action. These stories are compiled and have been used for disaster awareness seminars and have proven to be effective, since the real stories make participants feel that it may happen to them.

    Tremendous Tsunami caused by the 2011 Great East Japan Earthquake resulted in approximately 19,000 victims. The purpose of this research is to analyse quantitative relationships between its mortality rate and other factors using multiple regression analysis. The result shows that the following four factors such as -the distance from the epicenter, the ratio of inundation area, geomorphologic characteristic and “combined social variable"of elderly people rate with industry-have significant relationship to mortality rate. It is conceivable that high rate of elderly people and fishing industry led to high mortality rate in the seriously damaged areas such as Onagawa and Minami Sanriku, which implies importance of social factors.
