A STUDY ON TSUNAMI EVACUATION PLANNING IN CONSIDERATION OF CAPACITY OF EVACUATION PLACE

Abstract

The reconstruction plan of the East Japan great earthquake disaster was based on the idea of disaster reduction and the tsunami disaster measure in the plan was decided by a combination of disaster prevention measures such as hardware and software. Software measures need to consider regional characteristics such as population distribution, topography, infrastructure equipment etc. in each region. In this study, we focused on the capacity in the evacuation place and examined the evacuation plan that all people in the target area can evacuate in the central city area of Miyako City. We conducted simulation of tsunami evacuation in two cases. Fast cases, people who can evacuate by use of shortest time root. Second cases, people who have small total capacity of evacuation places are prioritized. As a result, we were able to obtain basic data on the consideration of the tsunami evacuation plan in the target area. By considering the total capacity of evacuation place, all evacuees can evacuate to evacuation places within the tsunami arrival time.
