Abstract
The purpose of this study is to analyze the relationship between hazard risk information and location of victim caused by heavy rainfall disaster in Japan. I have constructed database of victims (1259 persons) by heavy rainfall disaster from 1999 to 2018. In this study, 767 victims of flood and sediment disaster recorded in the database were analyzed. Eighty-seven percent of the victims of sediment disaster have died near the sediment disaster dangerous sites. On the other hand, 42% of flood disaster victims died near the inundation hazardous areas. As a result of analyzing the relationship between the flood disaster victims and the topography, 85% of the victims died in lowlands where there is a possibility of flooding. Most of the victims of flood disaster and sediment disaster occur geographically where disasters can occur. However, the current hazard map alone is not enough to understand the risk of flood disaster in the residence. It is important to construct easy-to-understand landform classification map information.
