A 7.3-magnitude earthquake that shook Fukushima and Miyagi prefectures off the coast of Japan, injuring more than 100 people, was an aftershock of the devastating 2011 quake that sparked the Fukushima nuclear meltdown, the nation’s meteorological agency has said.
The Japanese prime minister, Yoshihide Suga, expressed his sympathy to all affected and injured, although no deaths have been reported.
