Strong quake rocks northeast Japan

The quake which struck around 7:05 p.m. (1005 GMT) on Thursday had a preliminary magnitude of 5.6, the Japan Meteorological Agency said. There were no immediate reports of damage and no tsunami warning was issued.
The earthquake was centered off Fukushima, which was severely hit by the quake and tsunami in March that left more than 21,000 people dead or missing. Fukushima is about 150 miles (240 kilometers) northeast of Tokyo.
The March disaster touched off the worst nuclear crisis since Chernobyl, generating meltdowns, fires and explosions at the Fukushima Daiichi nuclear facility.
The plant’s operator said there were no signs of abnormalities at the plant from the quake on Thursday.
