China: Mountain at North Korea’s nuclear test site at risk of collapse

The single mountain under which North Korea most likely conducted its five most recent nuclear bomb tests could be at risk of collapsing, a Chinese scientist said. The latest test, the biggest yet, is thought to have been conducted at a site in Punggye-ri in the northeast region. Geophysicist Wen Lianxing, head of China’s seismic and deep earth physics laboratory, reported Monday that the risk prediction was based on data collected by more than 100 earthquake monitoring centers in China.
