Earthquake and tsunami hazard maps

From September 2022, the City of Nagoya will introduce new hazard maps for earthquakes and tsunami. The maps are published in Japanese on the City of Nagoya website, but if you can recognize some key expressions, you will be able to get useful information from the map that could save your life and the lives of those around you. Make time to study the hazard maps for your home, school, or workplace, and help yourself to be prepared for when an emergency arises.

Earthquake hazard maps　地震ハザードマップ

Nakamura Ward earthquake hazard map

The information shown on the new earthquake hazard map is based on damage projections for two potential scenarios for an earthquake originating in the Nankai Trough; specifically, the estimated largest class of earthquake based on both historical data, and a range of other possible factors.
The maps feature estimates of seismic intensity, liquefaction, and designated emergency assembly points (sites where you can initially evacuate from the immediate danger of tremors and fires) and places to obtain water.

Tsunami hazard maps　津波ハザードマップ

Minato Ward tsunami hazard map

As part of measures towards preventing human casualties, Aichi Prefecture designated areas estimated to be at risk if tsunami of the largest class were to occur as Tsunami Disaster Alert Zones (津波災害警戒区域) in July 2019.
The City of Nagoya's new tsunami hazard map incorporates data for the Tsunami Disaster Alert Zones within Nagoya City, and features estimated extent of inundation and water level, time until inundation, and the location of tsunami evacuation buildings where you can initially evacuate to protect yourself from the immediate danger of tsunami.
