Authorities from Tohoku Electric Power reported no irregularities at the Onagawa and Higashidori nuclear power plants. The Nuclear Regulation Authority confirmed that all nearby facilities operated without issues.
Japan is situated in a highly active seismic zone, experiencing about one-fifth of the world’s earthquakes of magnitude 6 or higher. This quake comes as a reminder of the country’s vulnerability to seismic activity.
The last major earthquake in the region was the devastating magnitude 9 quake in March 2011, which resulted in a catastrophic tsunami and led to the Fukushima nuclear disaster.
