- What is a Hazard Map?
Based on predictions of damage caused by natural disasters (floods, sediment disasters, earthquakes, tsunamis, etc.), hazard maps provide information on the scope of possible damage areas, evacuation routes, and evacuation areas. Hazard maps will help you perform the important tasks of confirming the location of your house and landmark buildings in relation to estimated flood areas and sediment disaster danger spots, and will also help you locate the nearest evacuation areas.
The purpose of these Hyogo Interactive CG Hazard Maps is to improve the day-to-day awareness amongst Hyogo citizens of the various types of natural disasters, and to enable a more appropriate and quick evacuation process in the event of a natural disaster.
Please ensure you fully understand the content of each hazard map before viewing the website.
These simulations do not consider disasters beyond the scope of our assumptions. Changes in landforms (height of housing areas, etc.) made after the simulations were performed are also not reflected. Therefore, please note that there may be cases where even uncolored areas on the maps are inundated, and indicated flood depths may differ in reality.
This map indicates flood vulnerable zones, based on simulations of floods caused by embankment collapse or river overflow during heavy rain. The scope and depth of floods are displayed with different colors.

This map indicates estimated floods caused by tsunami after the projected Nankai Trough megaquake. The scope and depth of floods are displayed with different colors.
Even in shallow floods, people may have difficulty walking if the water current is swift. Early evacuation is the key to survival.
This map is based on two simulations of floods caused by high tide water: simulations of the tidal levels during major typhoons in 2004 with the assumption that the sea embankments did not exist (only areas damaged during those typhoons); and simulations based on the highest estimated tide at major ports and fishery ports in Hyogo with the assumption that water flowed over sea embankments. The scope and depth of floods are displayed with different colors.
This map indicates estimated flood areas caused by the collapse of a reservoir embankment. The targeted reservoirs are those requiring special attention, as described in Hyogo Prefecture’s flood control plans.
During heavy rain, please be careful of floods around reservoirs, as well as rivers and waterways.
Using hazard maps, you can learn about the vulnerability of your neighborhood and find evacuation information for the area in which you live. Hazard maps can be used in various ways, among which the most important is to obtain the following information:
(1) Estimated flood depth of your house
(2) Evacuation areas
(3) Safe evacuation routes
The following is an example of how to find this information:
[Step 1]
Identify where your house, school or workplace is on the map. Check how deep floods can be, and whether they are situated in areas vulnerable to sediment disasters.
[Step 2]
Confirm the location of nearby evacuation areas. Evacuation shelters can be damaged by disasters as well, so check their locations and learn about the characteristics of those locations.
[Step 3]
Choose your own evacuation routes and evacuation shelter. Study possible routes and decide on a safe evacuation route and shelter for your family.
[Step 4]
Complete your family’s emergency map. Include information on your evacuation shelter, routes, meeting area, and contact information. When the map is complete, it’s a good idea to try actually walking to the evacuation shelter with your family/class members.
