- The nuclear tests conducted by North Korea in the nuclear test center Punggye-ri, deep in the ground under the Mantap mountain, have also led to various other earthquakes.
According to seismologists of the University of Columbia's Lamont-Doherty Observatory, the soil shows signs of 'stress' around the 2200 meter high. The mountain itself would suffer from a fatigue syndrome. Seismologist Paul Richard says to the Washington Post that three new bevels after the last test indicate 'triggered by the (nuclear) explosion. 'The area was not known as seismically active before the explosion.
Chinese scientists also hit alarms. They think that the mountain could collapse in a new nuclear test, possibly eliminating radiation.

Since 2006, North Korea has conducted six nuclear tests under mountain Mantap.
