Abstract

In recent years, floods due to unexpected heavy rain have been occurring one after another, and a review of regional disaster prevention plans has been required. The current regional evacuation plan is prepared by each municipality, and it is assumed that the citizens will use the evacuation shelter of the municipality where they live. However, in areas between rivers and municipal boundaries, there are evacuation districts where the citizens cannot go to own municipal evacuation center without crossing rivers that are likely to overflow will be identified. In this study, evacuation difficulties were extracted from map analysis of areas affected by heavy rains in western Japan, and it was clarified that the evacuation difficulties correspond to 33 in 26 municipalities in Chugoku district and Hyogo prefecture. Of these, 11 areas were evacuation centers without having to cross rivers if evacuation shelters in neighboring municipalities were available, but questionnaire surveys with local governments showed that only three evacuation sites were actually encouraging wide-area evacuation. In addition to staying in the districts, there were many places where there were no special measures, although they were recognized as evacuation difficult areas, indicating the need to promote wide-area evacuation in cooperation with municipalities in future disaster prevention plans.
