North Korea is "likely" to have conducted a nuclear test that caused an earthquake near a known testing site in the isolated country, South Korea's meteorological agency said on Wednesday.
The United States Geological Survey reported a 5.1 magnitude quake that South Korea said was 49 km (30 miles) from the Punggye-ri site where the North has conducted nuclear tests in the past.
"We suspect a man-made earthquake and are analyzing the scale and epicenter of the quake," a Korea Meteorological Administration official told Reuters by phone.
