TOKYO (AP) - A tsunami advisory has been lifted after a magnitude 7.3 earthquake struck early Saturday off Japan's east coast.
Tsunamis of up to 15 inches were reported at four areas along the coast, but the advisory for a region that included the crippled Fukushima Dai-ichi nuclear plant was lifted less than two hours later after the quake struck.
There have been no reports of damage on land so far, and Japanese television images show calm waters in the nation's harbors.
The quake hit at 2:10 a.m. Tokyo time. The U.S. Geological Survey says it was centered about 170 miles off Fukushima. The tremor was felt in Tokyo, some 300 miles away.
A disaster official in the Fukushima prefecture describes the quake as "fairly big" and says it cause "quite a bit" of rattling, but "nothing fell to the floor or broke."
