Niigata Prefecture 地震風險
Niigata faces the Sea of Japan and has a history of severe inland earthquakes. The 2004 Chuetsu (M6.8) and 2007 Chuetsu-oki (M6.8) earthquakes caused serious damage, while the Japan Sea Eastern Margin Fault Zone remains the largest offshore threat.
主要斷層・地震帶
The Japan Sea Eastern Margin Fault Zone lies offshore to the west of Niigata, capable of M7–8 earthquakes. The 1964 Niigata earthquake (M7.5) caused Japan's first documented large-scale urban liquefaction. Inland, the Shinano River Fault Zone is also active.
