On 13 February 2021 a powerful 7.3 earthquake struck offshore east of Tōhoku, Japan.
The earthquake occurred on a Saturday night at 23:07 JST (14:07 UTC). It had a maximum JMA intensity of Shindo 6+. It was followed by multiple aftershocks within less than an hour, with the strongest being a magnitude 5.3. The earthquake has been considered an aftershock of the 2011 Tōhoku earthquake which occurred almost ten years before this earthquake.
There were no reports of deaths or missing persons but the earthquake left more than 150 people injured and had inflicted significant damage across the Tōhoku and Kanto regions.
In addition, a non-destructive, 20 cm tsunami was observed at a port in Miyagi Prefecture in the early morning of February 14.
