Miyagi Prefecture 地震風險
Miyagi is the prefecture closest to the epicenter of the 2011 Great East Japan Earthquake. The entire Sendai Plain was inundated by tsunami, and the sea off Miyagi has a documented history of recurring M7+ earthquakes. The 30-year probability of an M7–8 earthquake off Miyagi exceeds 90%.
主要斷層・地震帶
The sea off Miyagi was closest to the epicenter of the 2011 M9.0 earthquake. The Pacific Plate continues to subduct beneath the North American Plate along the Japan Trench, accumulating stress. The Sendai Plain is flat, low-lying terrain — the 2011 tsunami penetrated more than 5 km inland, and future major events carry the same risk.
