Aomori Bay West Coast Fault Zone
From Wikipedia, the free encyclopedia
The Aomori Bay West Coast Fault Zone (青森湾西岸断層帯, Aomoriwan-seigan Dansō-tai) is an active fault zone on the Tsugaru Peninsula in Aomori Prefecture and its capital city, Aomori. It is paralleled to east by the west coast of Aomori Bay and to the west by the Tsugaru Mountains, running from north-northwest to south-southeast on the peninsula, through the city of Aomori, and finally extending south toward the Hakkōda Mountains. The zone is made up of three faults: the Aomori Bay West Fault, the Nogiwa Fault, and the Nyunai Fault. The Nyunai fault is a reverse fault.[1][2]
