TOKYO (Kyodo) -- An earthquake with a preliminary magnitude of 6.0 jolted Aomori Prefecture and other areas in northeastern Japan early Thursday, the Japan Meteorological Agency said.

No tsunami warning was issued. The 12:02 a.m. quake measured upper 5 on the Japanese intensity scale of 7 in the town of Tohoku in Aomori and lower 5 in Noheji and other areas in the prefecture.

The Economy, Trade and Industry Ministry's Nuclear and Industrial Safety Agency said it has not received any reports of abnormalities from nuclear facilities in two Aomori villages -- Tohoku Electric Power Co.'s nuclear power plant in Higashidori and Japan Nuclear Fuel Ltd.'s atomic fuel cycle facility in Rokkasho.

There are no abnormalities in the Fukushima Daiichi and Daini nuclear power plants in Fukushima Prefecture, Tokyo Electric Power Co. said.

Tohoku Electric Power also said there are no abnormalities in the Onagawa nuclear power plant in Miyagi Prefecture.

The agency said it believes the quake was not an aftershock of the March 2011 earthquake, while alerting people to take precautions against aftershocks measuring up to 4 on the Japan scale for a week.

The focus of the quake was off the Pacific coast of the prefecture at a depth of about 50 kilometers.
