In recent years, in large-scale disasters frequent in Japan, damage to supporters requiring evacuation action is enormous. Unlike sudden disasters such as earthquakes, flood damage can be predicted based on data, and although the speed of disasters is relatively moderate, it will suffer as much damage as well. However, at the time of flood damage, if early evacuation can be done before the damage expands, human damage can be drastically reduced. Therefore, in this analysis, the purpose is to reduce human damage caused by a new segmented evacuation information provision method, considering of correspondence to people who need more time to evacuate, we focused on physical conditions and regional characteristics. Through this analysis, it was possible to grasp the actual condition of the damage when it was inundated at the 1 breakage point of the river, which is the first class river flowing through Komatsu city, Ishikawa prefecture and the influence by town letters by changing information provision became clear.
