Society Disaster

Over the last decade, Japan has had 27 major earthquakes measuring lower 6 or higher on the country’s seismic intensity scale.

At 11:07 in the evening of February 13, 2021, an earthquake centered off Fukushima Prefecture caused shaking of upper 6 on the Japanese seismic intensity scale in Miyagi and Fukushima Prefectures. The Japan Meteorological Agency said that the hypocenter was around 60 kilometers below the surface, and the temblor had an estimated magnitude of 7.3. It was thought to be an aftershock of the devastating Great East Japan Earthquake of 2011.
