Magnitude 5.6 quake hits off northern Japan


A magnitude 5.6 undersea earthquake struck Japan Monday off the coast of Fukushima prefecture, though there were no immediate reports of damages.

The quake struck at about 4:00 pm (0700 GMT) at a depth of some 28 kilometres (17 miles), the US Geological Survey said.

There was no threat of a tsunami from the quake, the Japan Meteorological Agency said.

The crippled Fukushima Daiichi nuclear power plant, battered by a massive 2011 earthquake-generated tsunami and now undergoing decommissioning, has shown no irregularities in radiation levels, a spokesman for operator Tokyo Electric Power.
