EVALUATION OF DIFFICULT AREA FOR TSUNAMI EVACUATION IN KUSHIMOTO TOWN, WAKAYAMA PREFECTURE, JAPAN, BASED ON STRONG MOTION PREDICTION AND WALKING EXPERIMENT

Abstract

 During a scenario earthquake with M_W9.0 along the Nankai Trough, not only strong motion but also huge tsunami is predicted in Kushimoto Town, Wakayama Prefecture, Japan. Seismic waveforms in the Tsunami attack area were already predicted with very high density based on the SMGA models considering local site effects. In this paper, walking times from evaluation sites of local site effect to designated refuge places were measured. Using non-evacuation time based on the time history of instrumental seismic intensity and measured time based on results of the walking experiment, we evaluated the difficult area for tsunami evacuation in Kushimoto Town.
