地震風險：高
Aomori Prefecture 地震風險
Aomori's Pacific coast faces the Japan Trench, and the prefecture felt significant impacts from the 2011 Great East Japan Earthquake. Earthquakes occur frequently off the Sanriku coast, and multiple coastal areas carry tsunami inundation risk. The Sea of Japan coast faces a separate threat from the Japan Sea Eastern Margin Fault Zone.
主要斷層・地震帶
The Japan Trench runs close to Aomori's Pacific coastline, driving repeated large plate-boundary earthquakes. The coast around Hachinohe carries high tsunami risk; the Sea of Japan side is exposed to the Japan Sea Eastern Margin Fault Zone. Extensive coastal seawalls were built after 2011, but no seawall guarantees safety in an M8+ event — immediate evacuation to high ground is essential.
