An earthquake of magnitude 7.3 struck Saturday morning off Japan's east coast, near the crippled Fukushima nuclear site, the U.S. Geological Survey said. Japan's emergency agencies declared a tsunami warning for the area.
The quake hit at 10:10 a.m., the USGS said.
The tremor was felt in Tokyo, some 300 miles away.
Japan's Meteorological Agency raised the tsunami warning for the area of Honshu of about 3 feet. But the U.S. Pacific Tsunami Warning Center did not post warnings for the rest of the Pacific.

All but two of Japan's 50 reactors have been offline since the March 2011 magnitude-9.0 earthquake and ensuing tsunami triggered multiple meltdowns and massive radiation leaks at the Fukushima Dai-ichi nuclear power plant, about 160 miles northeast of Tokyo.
About 19,000 people were killed.
