Why it matters
What
North Korea's underground nuclear tests reactivated faults near Mount Mantap, including two parallel zones extending toward the China-North Korea border and Mount Paektu.
Why
Researchers say explosions altered stress fields and weakened crust, helping reactivate faults leading toward a dormant volcano known for its AD 946 eruption.
Watch
Further research will assess the fault activity, but there is no direct evidence that the tests changed Mount Paektu's volcanic activity.
