A nuclear test performed in 2017 by North Korea was extremely powerful that it moved the surface of Mount Mantap, which was the location of the test, as the explosion was seventeen times more powerful than the bomb that destroyed Hiroshima, stated a team of researchers from ISRO.
The three-member team of Indian Space Research Organisation comprising of Ritesh Agarwal, K.M. Sreejith, and A.S. Rajawat has published their research paper in the Geophysical Journal International.
According to the research scholars, the nuclear explosion caused sizeable surface deformation while the aspect of Mount Mantap had experienced displacement of up to 0.5-meter along the line-of-sight of Japanese Satellite ALOS-2.
Based on the information from satellite, the research team had predicted that the explosion yield was nearly 245 to 271 kilotonnes as compared to that of 15 kilotonnes bombs used on Hiroshima in the year 1945.
As there was no seismic information, the research team looked up at the skies to use the satellite information to measure the variations of the test site surface.
The research scholars also used the SAR (Synthetic Aperture Radar) data from the Japanese Satellite ALOS-2.
As per the research report, the explosion test was conducted at a depth of 542-metre below Mount Mantap.
