Aichi Prefecture 地震風險
Aichi is in the direct impact zone of the Nankai Trough earthquake. The low-lying Ise Bay coastal areas face high tsunami inundation risk, and Nagoya's urban infrastructure would suffer severe damage. The 70–80% probability Nankai Trough event remains the dominant threat.
主要斷層・地震帶
The Nobi Fault Zone, which caused the 1891 M8.0 earthquake, extends from western Aichi into Gifu. Ise Bay's enclosed geometry amplifies tsunami waves from the Nankai Trough — some low-lying coastal areas face inundation depths of up to 5 m. Multiple active fault lines have been identified beneath Nagoya City itself.
