A tunnel collapsed at North Korea’s Punggye-ri nuclear test site, according to Japanese media outlets. At least 100 people were killed and 100 more are feared dead; survivors are being evacuated from the area. It is unclear whether the collapse was the result of Pyongyang’s nuclear test in September.

At least 100 people died after a tunnel collapsed at the Punggye-ri nuclear test site in North Korea, according to Japanese news outlets. An additional 100 people are feared dead; rescue services are currently attempting to evacuate survivors.

Pyongyang conducted its sixth nuclear test at the site in early September. It remains unclear whether the explosion caused by the nuclear test led to the current tunnel collapse. The nuclear test caused a 6.3-magnitude earthquake that was felt in the surrounding area.

As reported by JOL in September, according to Japan’s Defense Ministry, the analysis of the earth’s movement at the test site shows that the amount of energy generated during the recent test was at least 160-kiloton strong, 40-kiloton more powerful than previous Pyongyang tests and no less than 105-kiloton stronger than the two bombs that destroyed Hiroshima and Nagasaki.
