Usage Guidelines
○ You can view the Inagi Disaster Prevention Map and Hazard Map (Flood and Landslide Disasters).
- It includes locations where citizens can evacuate, such as designated evacuation shelters, designated emergency evacuation sites, and welfare shelters for those requiring special care, as well as disaster prevention facilities like stockpile warehouses and water supply points within the city.
- Also included are the "Seismic Intensity Distribution Map," which shows the distribution of seismic intensities (indicating the strength of ground shaking) for the "Tama Eastern Direct Earthquake" expected to cause the greatest damage in Inagi City, and the "Liquefaction Hazard Map," which indicates the risk of liquefaction.
- The flood inundation assumption areas for the Tama River, Misawa River, inland water inundation assumption areas, and special warning zones for sediment disasters are included.
- The inundation assumption areas represent the results of simulations showing the regions where flooding would occur and the expected depth of flooding if heavy rain falls within the respective river basins.
- Depending on the rainfall pattern, changes in land use, and the development status of rivers and sewerage systems, flooding may occur outside the expected inundation areas, or the depth of flooding may differ.
- The duration of flooding indicates the time from when the water level reaches 0.5m or more due to flooding, until the water recedes to below 0.5m.
- The special sediment disaster warning areas show on the map the sediment disaster warning areas (Yellow Zone), special sediment disaster warning areas (Red Zone), and designated evacuation shelters during disasters.
Based on the Tamagawa Flood Inundation Assumption Area Map created by the Keihin River Office of the Kanto Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism, this shows the inundation situation in the event of flooding caused by the maximum assumed rainfall (total 588mm over 48 hours in the Tamagawa basin) leading to the Tamagawa River overflowing.

Based on the Misawa River Basin Flood Inundation Assumption Area Map created by the Tokyo Metropolitan Government, this shows the inundation situation in the event of flooding caused by the assumed maximum scale rainfall (maximum hourly rainfall of 152mm and total 24-hour rainfall of 690mm in the Misawa River basin) resulting in the Misawa River overflowing.
