Mount Doom: North Korea nuke test site could cave in & spread radiation – Chinese experts

‘The mountain where North Korea likely conducted its five most recent nuclear bomb tests could be at risk of collapse, potentially releasing radiation into the atmosphere, according to Chinese experts who measured shock waves caused by the blasts.
Scientists from the seismic and deep earth physics laboratory at the University of Science and Technology of China in Hefei, Anhu province, believe the most recent tests were carried out under a mountain at North Korea’s Punggye-ri test site, according to a statement published on their website.
The group’s leader, geophysicist Wen Lianxing, believes the margin of error for their prediction to be no more than 100 meters, citing data collected by more than 100 earthquake monitoring sites.
The data set includes an earthquake which was registered eight minutes after North Korea’s latest launch on Sunday, which Chinese authorities deemed a cave-in triggered by the explosion.’
