Tremor detected in North Korea after nuclear test

 Pyongyang, Sept 3: An artificial earthquake measuring 6.3 on the Richter scale, according to the US Geological Survey, was detected in the country’s northeast, not far from the Punggye-ri nuclear test site. The Korea Meteorological Administration initially put the scale of the earthquake at magnitude 5.7 and said that the seismic wave was recorded at 12:36 pm. The tremors were at least 10 times more powerful than the fifth test conducted last September, which caused a 6.3 magnitude quake, according to Japanese officials. Lassi Zerbo, the executive secretary of the Comprehensive Nuclear-Test-Ban Treaty Organisation, said that more than 34 stations picked up the seismic activity from the blast. Tremors could be felt as far as Vladivostok, Russia, one resident told CNN.
