A magnitude 7.3 earthquake was recorded off Japan's east coast early Saturday local time, but there were no immediate reports of damages, officials said.
A tsunami warning reportedly was raised for the Honshu area by Japan's Meteorological Agency in response to the quake. It struck about 2:10 a.m. more than 200 miles off the coast, according to the U.S. Geological Survey. The temblor reportedly was felt in Tokyo, about 300 miles away.
No tsunami warnings were posted for the rest of the Pacific by the U.S. Pacific Tsunami Warning Center.
On March 11, 2011, a magnitude 9.0 earthquake and tsunami killed thousands of people and caused major damage at the Fukushima nuclear power plant.
