North Korean nuclear weapons testing
North Korean nuclear weapons testing

On September 3, 2017, a nuclear test carried out in North Korea came to displace a mountain about three meters away according to a satellite view called SAR (synthetic aperture radar).

According to the images, specifically Mount Mantap moved 3.5 meters and left the mountain approximately 0.5 meters lower.

They report on this result in the digital edition of this week of the magazine ‘Science’ researchers Teng Wang, Qibin Shi, Shengji Wei and Sylvain Barbot of the Nanyang Technological University, in Singapore, as well as researchers from other universities.

That explosion occurred under Mount Mantap at the Punggye-ri nuclear test site in the north of the country, shaking the area like an earthquake of magnitude 5.2.

By modeling the event on a computer, the researchers were able to identify the location of the explosion. This is the first time that the complete three-dimensional surface displacements associated with an underground nuclear test are visualized and presented to the public.

The researchers estimate that the nuclear test, the sixth in North Korea and the fifth in Mount Mantap, had a yield of between 120 and 300 kilotons, roughly 10 times the strength of the bomb dropped by the United States on Hiroshima during the Second World War.
