Researchers have stated that the underground nuclear test conducted by North Korea on September 03, 2017, was powerful enough to move a mountain and 10 times stronger than the bomb dropped in Hiroshima during World War II.

Researchers, including those from Nanyang Technological University in Singapore and University of California, Berkeley, US, have showed how the explosion altered the mountain above the detonation.

The test that took place under Mt Mantap at the Punggye-ri nuclear test site rocked the area like a 5.2-magnitude earthquake, according to the study published in the Science Magazine.

Also, based on seismic recordings from global and regional networks, and before and after radar measurements of the ground surface from Germany’s TerraSAR-X and Japan’s ALOS-2 radar imaging satellites, researchers showed that the underground nuclear blast pushed the surface of Mt Mantap outward by as much as 3.5 metres and left the mountain about 0.5 metres shorter.
