When using

○ You can view the Inagi Hazard Map (Earthquake, Wind and Flood, Landslide).

[Hazard map (for earthquake)]
  • For those who need welfare considerations such as designated evacuation sites (municipal elementary and junior high schools, etc.), designated emergency evacuation sites, and disaster prevention facilities such as stockpile warehouses and water supply points. Secondary evacuation shelters (welfare evacuation shelters) are also listed.
  • In addition, a liquefaction forecast map showing areas where the possibility of liquefaction is expected in the city and a seismic intensity distribution map of the Tama Inland Earthquake, which is assumed to have a large impact on the city, are also posted.
[Liquefaction prediction map]
  • The liquefaction forecast map shows areas where the possibility of liquefaction is expected in the city.
    The area where the degree of liquefaction is determined in this forecast map is drawn based on the distribution of drilling materials, etc., and does not show a clear boundary line.
    In addition, most of the plateaus and hills are "areas with low liquefaction potential", but the land created by large-scale embankment construction may have the possibility of liquefaction depending on the embankment material. Please note that there is
[Seismic intensity distribution map]
  • In April 2012, the Tokyo Metropolitan Government announced the four assumed earthquakes (Northern Tokyo Bay Earthquake, Tama Inland Earthquake, Genroku Kanto Earthquake, Tachikawa fault zone earthquake), we publish the seismic intensity distribution map of the Tama Inland Earthquake, which is assumed to have a large impact on the city.
[Hazard map (for wind and flood damage, landslide disaster)]
  • Tama River Flood Inundation Area Map, Misawa River Basin and Tsurumi River Basin Inundation Area Map, Landslide Hazard Map are posted.
  • The estimated inundation (expected) area map shows the results of a simulation of the area and depth of inundation when heavy rain falls in each river basin.
  • Duration of inundation indicates the time from when the depth of inundation reaches 0.5m or more to when the water recedes to less than 0.5m.
  • The landslide hazard map shows landslide caution areas, landslide special caution areas, and designated evacuation shelters on a map.
