Hazard Maps
Hazard maps are maps that show the hazard expected in a region based on the topography of the region and the conditions of the town (evacuation sites, evacuation routes, etc.), together with information on evacuation sites. In Japan, the 2001 revision of the Flood Prevention Law mandated the creation of flood hazard maps, and today, hazard maps for earthquakes, tsunamis, floods, and other hazards are created for each region. Traditionally, these maps were distributed to residents as paper maps, but with the spread of the Internet, they have been digitized and are now available as interactive applications thanks to the widespread use of smartphones. While it is important to receive and respond to these maps immediately after a disaster strikes, it is even more important to have the necessary information in advance.
