Overview

Disaster Hazard Maps

Disaster hazard maps are disaster prevention materials that display natural disaster risk information such as floods, landslides, tsunamis, earthquakes, storm surges, and volcanic eruptions on maps. Created by local governments, the Ministry of Land, Infrastructure, Transport and Tourism, the Cabinet Office, and others, they provide information on expected inundation areas, evacuation sites, and evacuation routes. They are used for appropriate evacuation actions during disasters and for raising disaster prevention awareness during normal times.
