A strong earthquake has struck Japan, near the nuclear power plant which was hit by a tsunami earlier this year.
There are no immediate reports of damage or injuries.
The US Geological Survey said the magnitude-5.9 quake struck 62 miles (101km) east of the Fukushima Dai-ichi nuclear power plant at a depth of 23 miles (37km).
The quake hit 151 miles (244km) north-east of Tokyo.
The Pacific Tsunami Warning Centre did not immediately issue a tsunami alert.
The region lies on the “Ring of Fire” – an arc of earthquake and volcanic zones which stretches around the Pacific Rim. About 90% of the world’s earthquakes occur in the region.
