In this research, efficient operations issuing victim certificate with Information and Communication Technology (ICT) is discussed through analyzing aggregated data obtained from victim reception data, PC operation log, and video monitoring of victim behavior in case of the 2012 Kyoto-fu Nanbu Flood Disaster in Uji city, Kyoto prefecture. This research identified four key procedures for rapid and convincing operations to issue victim certificates: 1) establishing multiple reception desks for different purposes, 2) rejecting victims who failed to submit necessary documents at front reception desk, 3) establishing, visualizing, and sharing operation workflow among workers, and 4) training staffs on spot.

For the purpose of estimation of population affected by city gas supply disruption in an earthquake disaster, vulnerability factor of low-pressure gas pipelines is defined on the basis of non-earthquake resistant ratio. A functional fragility function in terms of shaking intensity is defined as a logit model with 50% exceedance level at SI=65kine considering the vulnerability factor and standard gas shutoff criteria. A grid cell dataset on population served by city gas supply is also developed based on penetration ratio inside/outside of DID. Observed and estimated population of disruption are compared for three major earthquake disasters during 2004-2011. Precision of estimation is approximately within a factor of two except for some extreme cases.

The present study, as a case study of the Great East Japan Earthquake, examined the value and the contents of the plan for receiving outside support. The Great East Japan Earthquake has taught us that a formulation plan is one important measure for improving power to receiving outside support. The aim is to ensure the promptness and effectiveness of emergency support in cooperation with other local goverments and voluntary organizations. In our analysis, the interview data of responders was adopted. And DRC typology was used to examine the value and the contents of the plan based on their points of view.

In the aftermath of Cyclone Nargis, Myanmar’s disaster management system has been developing with technical support from international aid．However, the support activities tend to center around the area stricken by Cyclone Nargis. Thus, a precise picture about community-level disaster management in areas other than that affected by Cyclone Nargis has yet to be revealed. This study deals with a flood management in Bago township, where a large-scale flood hit in 2011. We conducted interviews with local residents and government officials in charge of disaster management to clarify the actual conditions and problems they faced during the disaster. SWOT analysis was then conducted by dividing these conditions and problems into four categories (Strengths, Weaknesses, Opportunities and Treats). Finally, three strategies were proposed to improve Myanmar’s disaster management capacity in terms of government human resources, disaster management system, information infrastructure and capacity of community.

Recent public estimation of tsunami damage has prompted the revision of existing evacuation plans in Japan. It is especially important to establish countermeasures for visitors who are not acquainted with the risk of places near the water. This study evaluates the spatio-temporal evacuation behavior of visitors fleeing from the beach to an evacuation shelter at an evacuation drill. The data of their behavior were tracked using mobile GPS devices and fixed-point video-recordings specifically focused on detecting behavior pattern. In addition, visitor’s awareness of the risk was addressed through a questionnaire survey. Through those analyses, having a guide method was found to be a very important factor affecting the visitor’s behavior.

When a natural disaster occurs, victims’ information needs vary with their personal attributes. (e.g. age, gender, occupation and so on), and the needs also vary with the time passed from the disaster. Thus, it is required to make a system that enables victims to easily satisfy their information needs considering their personal attributes and time phase. As a fundamental study before making such a system, we did time series analysis of circumstances of victims by applying text mining method for newspaper articles about the 2011 Great East Japan Earthquake. As a result, we clarified that it is possible to find the time series variation of correlation between some major personal attributes and provided information from newspaper articles.

This paper reports on an exploratory study of “Zest for Living in disaster” to propose a hypothesis based on a qualitative survey and analysis on the text data of personal interviews with 78 victims of the 2011 Great East Japan Earthquake disaster. The main results are as follows: 1) Correspondence and handling cases are divided into four categories of Emergency response immediately after a disaster, First response, Recovery response and Common phases. 2) Appropriate response is classified into Personal character, Attitude and habit, Social capital, Individual capability and resources, and Disaster experiences of “Zest for Living in disaster” in the past.
