North Korea’s nuclear test site has collapsed … and that may be why Kim Jong-un suspended tests. The mountain’s collapse after five blasts may be reason behind North Korean leader’s declaration that he would freeze tests and shut down the site. North Korea’s mountain nuclear test site has collapsed, putting China and other nearby nations at unprecedented risk of radioactive exposure, two separate groups of Chinese scientists studying the issue have confirmed. A research team led by Wen Lianxing, a geologist with the University of Science and Technology of China in Hefei, concluded the collapse occurred following the detonation last autumn of North Korea’s most powerful thermal nuclear warhead in a tunnel about 700 metres (2,296 feet) below the mountain’s peak.
