Geological surveys and seismic telemetry confirm that the mountain hosting North Korea’s primary underground nuclear testing complex at Punggye-ri suffered catastrophic structural collapse following its sixth nuclear test.

Seismologists at the University of Science and Technology of China concluded that the detonation of a thermonuclear device estimated at over 100 kilotons triggered structural fracturing throughout Mount Mantap. Subsequent secondary tremors indicate roof cave-ins, effectively transforming portions of the tunnel complex into an environmental ‘chimney’ prone to radioactive gas venting.
The physical degradation of Punggye-ri significantly contextualized Pyongyang’s subsequent diplomatic declarations regarding the moratorium on testing, suggesting the facility had become operationally compromised prior to formal decommissioning ceremonies.
