説明

In local disaster prevention plan, few local municipalities consider unexpected tsunamis, and most of them make a tsunami inundation hazard map following a scenario which is provided by the central government. Hazard map which shows ranges and uncertainties of the assumption can be more reasonable to understand the tsunami risks in the local scale. Local municipalities also should know the disaster resistance capacity of the region in advance to adjust occurrence of unexpected event. This study assesses the resistance capacity of local communities against tsunami inundation by continuous increase in tsunami intensity. The analysis shows the tsunami magnitude which changes the stage of disaster response referring to loss of shelter capacities in the administrative side and the potentially vulnerable and high risk areas against tsunami inundations in the residence side.
