A magnitude 5.3 earthquake rocked Japan's Fukushima prefecture early Friday morning, US seismologists said, but no tsunami warning was issued.
The epicentre of the earthquake was 22 kilometres (14 miles) below the ground, according to the US Geological Survey. It struck 20 kilometres west of the city of Iwaki, bordering the Pacific Ocean, at 02.25 am (1725 GMT).
The epicentre was also about 50 kilometres southwest of the damaged Fukushima Daiichi Nuclear Power Station, which was crippled by the major quake and tsunami in March, 2011.
