Abstract

Indicators for evaluating recovery from a disaster include the recovery rate of lifeline and infrastructure. However, there are few indicators to evaluate the impact of disasters on people's daily behavior. Recently, with the spread of information communication terminals such as smartphones, it has become possible to obtain enormous data such as people's location information and moving velocity. This study proposes a methodology of quantifying the impact for people's behavior at the disaster and clarifies the recovery process by using moving velocity from the point type flowing population data in the 2016 Kumamoto earthquake. The results showed that there was a decrease in the moving velocity by the earthquake and the recovery process of people's activities were different among each cities.
