Clarifying the transition of workload for victims life reconstruction support programs in affected local governments using the victims master database - Comparison between the 2007 Chuetsu-oki earthquake and the 2016 Kumamoto Earthquake

To realize an effective disaster response, the entire picture of the damage situation must be grasped. which is time consuming, especially after a huge disaster. After the 2011 East Japan Earthquake, it took about six months for local responders to grasp the general damage situation because they inspected the degree of damage for each building and certified the degree of damage for each victim. This study aims to clarify how much work occurs at an actual disaster site. We selected the 2016 Kumamoto Earthquake and the 2007 Chuetsu-oki Earthquake as case studies, and collected work logs from affected municipalities to determine the transition in the work volume. These logs were analyzed chronologically. It took about three months to certify the degree of building damage for each victim regardless of the severity of damage and area characteristics.
