An earthquake with a magnitude of 7.3 struck off Japan's east coast at about 2:10 a.m.Tokyo time, as the country's emergency agencies issued a tsunami advisory for the region, the U.S. Geological Survey said, reported the Associated Press. There were no immediate reports of damage on land.
The earthquake was felt 300 miles away in Tokyo, news reports said.
"[The earthquake] was fairly big, and rattled quite a bit, but nothing fell to the floor or broke. We've had quakes of this magnitude before. Luckily the quake's center was very far off the coast," Satoshi Mizuno, an official with the Fukushima prefectural government's disaster management told The Associated Press by phone.
About 19,000 people were killed in the 2011 earthquake, which reached 9.0 on the Richter scale.
The Fukushima plant was damaged in a 2011 earthquake and tsunami. Japan's meteorological agency issued "3-foot tsunami advisory for a long stretch of Japan's northeastern coast, and it put the quake's magnitude at 7.1. The U.S. Pacific Tsunami Warning Center did not post warnings for the rest of the Pacific," The AP also reported.
