ETHNOGRAPHIC ANALYSIS OF INDIVIDUAL BEHAVIOR FOLLOWING THE HANSHIN-AWAJI EARTHQUAKE DISASTER

摘要

The Hanshin-Awaji earthquake disaster has developed a new paradigm for disaster research. In term of the lifeline earthquake engineering, post-disaster human behavior is an important issue for developing the restoration strategies. This paper presents an ethnographic analysis of post-disaster human behavior focusing on the transition of the victim's residence and its determinants after the Hanshin-Awaji earthquake disaster. The item-category data were semi-structured interviews of 32 victims in Nishinomiya-city. The three sites were selected in the city, downtown, midtown and uptown. Each interview took about 2 hours in total to acquire the information of the significant events in their post-disaster response including their residence transition for the first one year after the earthquake. Based on the item-category data sets, multi-dimensional quantification analyses were carried out to identify key factors for determining the transition of their residence throughout one year after the earthquake. From the analysis, three different time phases for victim's behavior are identified. For the first 10 hours, victims tended to be inactive. For the first 100 hours, the loci of residence were divided into three groups such as home, shelter and relocated to other jurisdiction. For the first 1000 hours, the victims restarted their life through their personal contacts. In addition, the transition of the victim's residence is deeply dependent on the life stage of each individual. The lessons learned are compiled to'Disaster Ethnography"to understand the disaster process for the future disaster management.
