Understanding the damage situation of social infrastructures and geographical characteristics in the tsunami anticipated inundation area of the great earthquake along the Nankai Trough etc.

Abstract

In recent years, the occurrence of the great earthquake and its accompanying tsunami along the Nankai Trough has raised concerns, and it is assumed that extensive damage will occur in a wide area, from Kanto to Kyushu. In the past, the Great East Japan Earthquake and the Kumamoto earthquake damaged various social infrastructures such as the nuclear power plants and the public facilities tremendously and various failures occurred due to malfunction of blackouts, traffic congestion etc. In this study, we aim to examine the prospective facility's location and disaster prevention measures. For this reason, we used the data of the tsunami anticipated inundation area on the great earthquake along the Nankai Trough etc., to grasp the number and the depth of social infrastructures in the area. We also analyzed the geographical characteristics such as the altitude of the tsunami anticipated inundation area and its distance from the coastline.
