Fukushima Prefecture 地震風險
Fukushima is where the 2011 Great East Japan Earthquake triggered the Fukushima Daiichi nuclear disaster. M7.3 (2021) and M7.4 (2022) earthquakes followed. Offshore fault activity continues, and ongoing vigilance is warranted.
主要斷層・地震帶
Pacific Plate subduction continues to generate aftershocks off Fukushima — M6–7 earthquakes have recurred repeatedly since 2011. Inland, the Iwaki fault system and other active faults exist. Because Fukushima Daiichi nuclear plant is located here, checking official Nuclear Regulation Authority statements alongside JMA alerts is advisable during any significant seismic event.
