(TOKYO) -- A 7.3-magnitiude earthquake struck the northeast coast of Japan on Friday, triggering a tsunami warning for the region.
The quake hit just after 5 p.m. local time off the coast of Miyagi prefecture.
There was no risk of a widespread tsunami, according to the Pacific Tsunami Warning Center.
The Japan Meteorological Agency said a wave of 20 centimeters reached the shore in Miyagi prefecture and a wave of three feet was recorded in the city of Ishinomaki at 6:02 p.m. local time.
According to the Tokyo Electric Power Company, no damage has been reported at monitoring posts and water treatment facilities at all reactors at the Fukushima Dai-ichi plant, which was crippled by a magnitude-9.0 earthquake and ensuing tsunami that slammed into northeastern Japan on March 11, 2011. That quake killed or left missing some 19,000 people, devastating much of the coast.
There are more than 3,000 people who work at the plant daily and they have been told to stay inside and move to higher ground on the site.
