[050] A Survey on the Process of the Rebuilding of Mashiki Town Victim's Life after the Kumamoto Earthquake
Keywords:Kumamoto Earthquake, Mashiki Town, Victim’s life rebuilding support, GIS
In 2016, the Kumamoto Earthquake, which observed seismic intensity 7 twice, caused great damage to Kumamoto Prefecture. Almost 4 years after the earthquake, many residents have regained their lives. However, as of June 2020, 523 residents (188 households) are still living in temporary housing, indicating the diffi culty of rebuilding life after the earthquake. In this study, we aim to grasp the actual situation of life rebuilding support in Mashiki Town in the Kumamoto Earthquake.The study was conducted by the following methods. (1)We compiled and analyzed results of the damage certifi cation survey of buildings in Mashiki Town during the Kumamoto Earthquake in GIS. (2)We compiled the characteristics of the victim rebuilding support system, a system that provides public funds to households whose homes were damaged in a disaster.(3)We clarified and summarized a questionnaire survey which was conducted on households that had house rebuilding, and the process of house rebuilding in this study.Many buildings were damaged in Mashiki Town, 3,552 completely destroyed, 1,006 heavily damaged, 2,887 partially damaged, 4,956 sustaining minor damage, for a total of 12,401. Victim's life rebuilding support is designed to support households that have suffered significant damage to their life infrastructure because of natural disasters by providing them with life rebuilding support funds. The support targets are completely destroyed and heavily damaged. A questionnaire survey was conducted by identifying “households whose homes were damaged and whose homes were rebuilding or repaired at the same location”. Of the survey targets, we investigated the method of rebuilding their homes, and found that 34.8% were rebuilt and 65.2% were repaired. The most common support programs applied for were victim's life rebuilding support (basic subvention), disaster relief donation, and victim's life rebuilding support (additional subvention). The disaster relief donation was initially intended for households whose houses were partially damaged or more, but the damage to the entire town was extensive, especially houses with minor damaged, which accounted for more than 40% of the total damage. In terms of the time taken to rebuilding their homes, the time required for repair was 8.9 months, while the time required for rebuilding was 19.3 months, a diff erence of 10.4 months. The reasons for this are (1)delays in receiving damage certifi cate, (2)concerns about rebuilding method, and (3)delays in construction start due to a lack of craftsmen. By considering ways to support the resolution of these issues, we can take an approach to rebuilding life as soon as possible.
