    In order to prevent injuries in earthquake, person at home is nessesary to take apporopriate actions, but it is difficult to make an accurate snap judgment during an earthquake. As one of the solution strategy, we have been developing an evacuation guidance system using five senses information. In the step of this study, we tried to propose a monitoring system capable of judging some events from indoor sound information at normal and earthquake. A recognition system function built in the system identifies the occurrence and location of events including living activities and indoor damage caused by earthquake through the analysis by deep learning.

    This study analyzed spatial data of the affected areas by the debris flows in the heavy rain disaster of July 2018 and sediment disaster warning zones in Hiroshima prefecture. We revealed that almost 50% of the buildings in the affected areas are located still outside of the latest sediment disaster warning zones. Overflow and wide spreading of the debris from rivers were observed in the areas underestimated by the warning zones. Debris flow propagation analysis is performed to simulate the debris flow inundation areas based on the Flow-R and digital elevation model. We found that the analysis based smaller travel angle are required in order to reproduce the wide spreading of the debris in the downstream of rivers.

    In recent years, Tokyo inland Earthquake has been concerned. According to the earthquake damage estimation of Central Disaster Management Council, fire-related damages account for 70% of the whole so fire departments which have limited fire fighting power have to reduce disaster. In this study, we focused on resident’s wide-area evacuation in case of post-earthquake fures and proposed which risk is most critical for reducing human damages using the exist evacuation simulator. As a results, in the target area, if fire brigade can select enough fires, extinguishing activities considering resident’s evacuation are most effective to reduce human dmages and it may be helpful for extinguishing activities at that time.

    The questionnaire survey was investigated for welfare facilities in the area where major floods occurred in recent years. In addition, the interview was investigated to welfare facilities which got away from a flood with help of other people. One of the problems is welfare facilities can’t get help of other people in times of an emergency. We insist that it is important to get the help of other people at the time of moving to a safe place. The welfare facilities should make good relationship with residents, information sharing about the evacuation planning , evacuation drills with the helper.

    The aim of this study is to clarifiy the reasons why residents accept the designation of the Orange Zone which means alert area for tsunami disaster and the concerns of municipalities. As a result, the following became clear; (1)Whether or not to accept the designation depends on residents’ proper understanding of the system and objectives of this area, and elimination of the concerns. (2)On the other hand, the municipalities do not come to a concrete consideration becuase that they are busy, that there are few designated records, and that surveys take much time. (3)It was pointed out that the consideration could be gave up because they can’t gain the understanding of the residents, they must coordinate with the town development policy, and they concern about reputational damage and impact on tourism.

    What has the local disaster learning in schools and story telling in families after the Great Hanshin-Awaji Earthquake(1995) passed down to the young people in the local post-disaster generation? The narrative by 6 young persons in the generation reveals that they have “medimemory” about the earthquake. In medimemory, they feel not having experience about the disaster, but feel it familiar. This paper discusses the repetitive story telling in family generates the medimemory in children and school provides them social view about the disaster including the image of death and destruction. Then, young people after the earthquake re-creates the image of the disaster, medimemory. They try to take their own responsibility in medimemory to inquire what they can(not) do to pass down their memory.

    Since the Great Hanshin-Awaji Earthquake, the importance of post-disaster psychological care has been recognized.During the 2016 Kumamoto Earthquake, school counselors (SC) were dispatched from all over Japan to care for the minds of children. In this paper, we analyzed the actual situation and issues of the SCs dispatched at the time of the Kumamoto earthquake based on several reports and interviews with those who received support.As a result, it was found that the acceptance system of the dispatched SCs can be classified into five functions of the incident command system (ICS). The block system adopted by SC in Kumamoto City was effective for commandintegration. On the other hand, some of the dispatched SCs were confused about the support methods. In order to properly provide SC support, it is important to utilize the ICS concept and centralize command so that the instructions of the site manager can be thoroughly provided.

    The volcanic hazard map is one of the effective proactive measures for volcanic disasters. However, the general public has little interest in the hazard maps because it is not easy to understand them. To address this problem, this study develops a volcanic hazard map using augmented reality (AR). The effectiveness of the proposed AR hazard map was verified through the workshops held in Fujiyoshida City, in which participants actually used the prototype map. As a result, it was clarified that the AR hazard map could effectively supplement a printed hazard map and it was also found that the display switching function of the hazards was particularly effective for promoting understanding.

    This study aimed at a mid and long term forcast of Japanese Economy after the anticipated Tokyo Inland Earthquake disaster. Delphi method survey to ESP forcasters was conducted, and a group interview survey to some of the forcasters was also held to build a worst scenario of the economy. The primary finding was that the most of respondents of the survey anticipate negative but mild economic consequences. The worst scenario that we found here was a coincidence of inflation, interst hike, and depreciation of Yen’s value, due to the loss of credibility of Japanese economy.

    This paper presents the results of the discussion on the study on the qualitative risk degree for human casualties for earthquake disasters as part of a study to assess the mitigation and reduction level of regional disaster risk using local residual risk. The authors have already proposed a prototype model to analyze the "regional residual crisis degree" for four risk scenarios of the Tokyo Inland Earthquake. By improving the prototype model, in this study, the author proposes a qualitative crisis degree for human casualties from earthquake disasters that incorporated the social vulnerabilities, i.e., human losses caused by earthquake fires and tsunamis.

    In this study, I focus on the phenomenon that recipients of information understand that “a place is safe if it is not colored on the hazard map” and “there is no need to evacuate if there is no evacuation information”. We proposed a conceptual diagram to explain the mechanism by which risk information is understood by the receiver as safety information in spite of the intention of the sender of the information, using a theory of the ivnverse proposition of disaster information. The proposed conceptual diagram was applied to a hazard map and its effectiveness was discussed.

    The objective of this paper is to clarify the actual use of the Great East Japan Earthquake archives and to contribute to the effective preservation and utilization of disaster records. In the areas affected by the Great East Japan Earthquake, local governments, researchers, and the media have created disaster archives that are important for long-term preservation. On the other hand, the purposes and situations of the utilization of archives vary from one user to another, and the whole picture is still unknown. In this study, a questionnaire survey was conducted among local governments, school boards and social welfare councils about the actual use of archives. Based on the results, some conclusions about their characteristics and usage patterns were drawn through cross-tabulation. This indicates the importance of the use of the archives after the earthquake.

In recent years, a number of studies in foreign countries have argued that hot spots policing can be effective in reducing crime. However, the number of crimes and city environment are different from Japan and foreign countries.Our study attempted empirical experiments for crime deterrent in our country. First, examining crime prediction using retrospective crime data in Nagano prefecture, the hot spots were identified by crime prediction methods. Next, in order to assess the crime deterrent effect, we conducted hot spots patrol by the police. Finally, we detect statistically significant crime reduction in hot spots area.

    For effective disaster response, it is important to record and succeed past disaster lessons learned. In this study, a questionnaire survey for local governments affected by major earthquake disasters was conducted to understand their efforts and challenges on succession of the disaster response lessons to the next generation. As a result, although many affected local governments have organized and issued their lessons, there is a tendency that disaster prevention drills and training for staff have not been carried out mainly due to insufficient time to prepare for. It implies that affected local governments should utilize the existing disaster prevention drills and training, and drills and training for practical operations should be effective such as shelter management or issuance of disaster damage certificate.

    Typhoon No. 15 in the first year of Reiwa caused great damage to Chiba Prefecture. In this disaster, damage to lifelines such as power outages, water outages, and interruptions in telephone and mobile phones were severe. Furthermore, since the temperature was high immediately after the disaster, there was concern about health damage to the elderly.Therefore, from the perspective of business continuity, it is important to deal with disasters that consider the health of the elderly. In this study, we conducted a mailing survey on the disaster situation and disaster response for the nursing homes in Chiba Prefecture. As a result, it was found that the health of the elderly was related to lifeline damage, evacuation status, and food provision status.

    After an earthquake, early damage estimation of damaged buildings is important for Business Continuity Plan (BCP). Bayesian inference for damage probabilities using real time monitoring data is proposed. The parametric studies of the damage probability model are conducted. Considering an actual earthquake, the case of non-uniform distribution of monitoring structures at each seismic intensity is studied. Simulations using damage data due to historical earthquakes show the influence of the monitoring ratio on the reliability and damage level distribution. The applicability and consideration for uncertainty of damage probability of the proposed method are shown.

    This paper aims to measure effectiveness of an educational board game as an exercise tool for disaster recovery at local level. The consecutive surveys were administrated for the participants of the Workshops three times: before playing the game, after the game, and two months later from the playing. The results show that:1) participants were highly motivated to share the game to others, 2) the game helped participants to understand individual and local recovery, and 3) the options for housing recovery were diversified after playing the game while some participants could not decide the best option of housing recovery due to the financial capability and uncertainty of disasters.

    In this paper aims to consider support measures for each acceptance method. We tried to verify the relationship between acceptance method and (1) seismic intensity, (2) work that took a long time to perform , and (3) the coping method for the increased work. When the seismic intensity was 6+ or higher, 77.0% of the facilities responded to voluntary acceptance or shelter with additional assistance. When the facilities responded to voluntary acceptance or shelter with additional assistance, the particularly large amount of work were to secure and provide food. The acceptance system created by the emergency system of professional staff contributed to the smooth operation of the shelter. In case of voluntary acceptance, it was useful for the professional staff to carry out their duties by making good use of external human resources.

    Based on lessons learned from the Kumamoto earthquake, the Ministry of Internal Affairs and Communications (MIC) discussed a scheme for dispatching local government officials to the affected areas and established a “system for securing staff to support municipalities in the affected areas”. The system was put into operation from the torrential rains of July 2018, but the process for providing on-site support has not been indicated at this time. When a disaster occurs on a scale that cannot be handled by local government resources alone, a rapid request for assistance and smooth acceptance of assistance are necessary. The purpose of this study is to develop a scale for evaluating the local government's ability to request support at the time of a disaster, and to identify common and individual differences in the disaster management process of ”the General Adviser for Disaster Management“ at the disaster management headquarters. A standardized disaster response process is also proposed based on the results.

    In this study, we conducted a survey on the implementation of training in the disaster management departments of municipalities in Aichi Prefecture. Due to the shortage of human resources and time in the disaster management department, the implementation of training within the disaster management department and the dispatch of staff to training outside the prefecture tended to be limited. The expectations by municipal staff are as follows. In the training within the municipalitiy, it is expected that cooperation within the organization and establishment of a disaster response system. On the other hand, in training "outside" the municipality, it is expected that knowledge and skills such as regional issues at the time of a disaster, disaster legal system, disaster mechanism, etc.

    In the past large-scale disaster, inefficient disaster response occurred due to lack of human resource management on local government. This is because there is no simulation method of human resource allocation against necessary work volume and it is difficult to examine human resource management before and after disaster occurs. Based on the background, this paper proposes novel method for simulating human resource management for optimal allocation by estimating finishing date of disaster response and necessary volume of receiving manpower from outside. In addition, we simulated the human allocation on disaster response and validated efficiency of the proposed method.

    Food is one of the important living bases, and a stable supply is required from the viewpoint of social welfare. If the agricultural production infrastructure is severely damaged, or the distribution system fails, by a shock such as a disaster, it could have various negative effects on various places. In order to consider effective countermeasures, it is important to know, for a shock occurred somewhere, how much inter-regional flow of foods changes through the supply chain, and how the changes can affect regions. In this research, an inter-regional flow estimation model is constructed under the assumption that supply of agricultural products decreases due to some exogenous shock, and we carry out a case study to find characteristics of inter-regional flow changes.
