Scientists recorded 1,399 local quakes since North Korea began its underground nuclear tests—a spike unlike anything the region has seen since seismic activity was first catalogued there.
Between 2006 and 2017, North Korea conducted six underground nuclear tests at its vast testing site at Mount Mantap in North Hamgyong province. Typically, underground explosions trigger an intense burst of minor earthquakes that die down once testing stops.
