A 7.3-magnitude earthquake caused some deficiencies at two of the three nuclear power plants (NPPs) located in relatively close proximity to the fault, but it did not cause any safety concerns, according to Japan’s Nuclear Regulation Authority (NRA).
The quake struck about 60 kilometers off the coast of Japan on March 16 at 2:36 p.m. UTC. The NPPs affected include the Fukushima Daiichi facility, site of the infamous nuclear disaster in February 2011. Other potentially vulnerable facilities were the Fukushima Daiini and Onagawa nuclear power stations.
