The US Geological Survey said it had detected a tremor with a 4.9 magnitude. A shallow 4.9 magnitude quake was detected near a known nuclear test site on Tuesday morning, the USGS said.
South Korean media also reported a "man-made earthquake" in its northern neighbour. A UN monitoring agency described it as an "unusual seismic event" with "explosion-like characteristics".
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". There has been no word yet from North Korea, but it announced plans for a third nuclear test last month.
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. The UN Security Council had warned of "consequences" if Pyongyang went ahead.
China's Earthquake Administration described it as a "suspected explosion", AFP reported. Japan's Meteorological Agency said the tremor was "different from a normal earthquake". 'High-level'
