Remember when it was in the news that some of the workers in North Korea died during a nuclear test, and that there was a worry of the mountain above North Korea's test site collapsing?
Well...it's now likely that mountain has collapsed according to a new study and information by geologists at the University of Science and Technology in China.
Because the mountain has collapsed, these geologists are now concerned that built-up radioactive fallout could escape and start spreading, mainly into China and South Korea, but the main danger is to Kim Jong Un's own citizens (I'm sure he's real torn up about it).
