It is important to make up evacuation plan based on results of a detailed survey of damage caused by a natural disaster. As a case study of Senndannyama area, Toyama prefecture, damaged by torrential rain in 2023, we visualized a location where landslides occurred due to torrential rain, by using GIS. Also, we surveyed the correspondence between a location of landslides and evacuation routes which were used in case of the evacuation drills. This investigation show that some landslides occurred on the evacuation route. And we found that residents are forced to choose limited evacuation routes due to small number of roads, and sometimes, the difference of elevation along the evacuation route is large.
