No damage reported from Japan magnitude 6.7 quake
A warning of a tsunami of up to 50 cm (20 inches) was lifted about an hour after the quake, which occurred around 6:51 a.m. (2151 GMT Wednesday), but authorities warned residents to be wary of mudslides.
Tokyo Electric Power Co, struggling to control radiation leaks at its Fukushima Daiichi nuclear plant due to damage in the March disaster, said there was no impact from Thursday's quake on its efforts to bring the reactors under control.
The Nuclear and Industrial Safety Agency said there were no reports of abnormalities at Tohoku Electric Power's Higashidori and Onagawa nuclear power plants in northeast Japan. Operations of these reactors have been halted since the March disaster.
The focus of the tremor was 20 km (12 miles) below the seabed off Iwate and about 500 km (300 miles) northeast of Tokyo, the Japan Meteorological Agency said.
