SIMULATION OF TSUNAMI EVACUATION CONSIDERING DIFFERENCE EVACUATION TIMING BY USING ARTISOC

Abstract

 In this study, different evacuation start times were considered in the evacuation simulation from the tsunami caused by the Great East Japan Earthquake in the Shikaori area of Kesennuma City, Miyagi Prefecture. The evacuation completion rate and the number of deaths were quantitatively evaluated. As a result, in the case of later the evacuation timing for local residents, the higher number of deaths and the lower evacuation completion rate were calculated. In addition, there is a nonlinear relationship between staggered evacuation and the number of deaths, showing that temporal dispersed evacuation is one of the effective methods for efficient tsunami evacuation. Also, the result of the present study shows that different evacuation timing and early evacuation is of important for local residents to decrease the number of their deaths and to decrease the evacuation completion rate.
