North Korea 'earthquake' amid nuclear test fears

Tuesday, 12 February 2013 - 13:06


Seismic activity has been detected in North Korea, several nations say, in what could be a sign of a widely-anticipated nuclear test.


The US Geological Survey said it had detected a tremor with a 4.9 magnitude.


South Korean media also reported a "man-made earthquake" in its northern neighbour.


North Korea said last month it was planning to carry out its third nuclear test - despite a threat from the UN Security Council of "consequences".


The USGS said the quake occurred at a depth of 1km. It put the epicentre close to North Korea's known nuclear test site in the northeast of the country.
