A powerful earthquake struck off Japan's northeastern coast late Thursday, but no tsunami warnings were issued.
The U.S. Geological Survey says a 6.2 magnitude quake struck near the coast of Honshu, about 155 kilometers east of Tokyo, at a depth of 10 kilometers.
Japan's Meteorological Agency said there was no risk of a tsunami. There were no immediate reports of damage or injuries.
A massive earthquake and tsunami devastated northeast Japan in March, leaving nearly 20,000 people dead or missing and triggering a meltdown at Fukushima Daiichi nuclear power plant.
A spokesman for Tokyo Electric Power Company, Fukushima's operator, said the plant was not damaged by Thursday's quake.
Some information for this report was provided by AP and AFP.
