North Korea has conducted five underground nuclear tests since 2006.

North Korean time at a depth of 537.6 km below the East Sea, 176 kilometers east-southeast of Hoemul-li, North Korea, the agency said on its website.

An unusually strong tremor struck deep below the seabed east of North Korea early Thursday, with South Korean and Japanese quake observers recording its magnitude at 6.3.

A magnitude-5.8 natural disaster that occurred off North Korea's east coast Thursday (local time) was not caused by a nuclear test, the US Geological Survey said.

An quake with a magnitude of 6.7 struck off the town of Rabaul in the south Pacific nation of Papua New Guinea on Thursday, the United States Geological Survey said.

"It occurred at 500km below the seabed", he told Yonhap news agency. South Korea's Defence Ministry said there was no indication that North Korea had carried out a nuclear test. Major Jamie Davis, a Pentagon spokesman, cited the depth and location from initial reports for ruling out a nuclear test. "It's a natural quake", John Bellini, a geophysicist at the USGS National quake Information Center, told Yonhap by phone.

Japan's meteorological agency reported a 6.3-magnitude quake, but did not issue a tsunami warning.

Even if a ship was sailing over the epicentre at the time of the quake, it wouldn't have noticed anything, Cho said.
