Latest N Korea nuclear test moved a peak by few metres: ISRO team

A study conducted under ISRO's KM Sreejith has stated that North Korea's latest underground nuclear test was powerful enough to shift the surface of the mountain above the detonation point by a few metres. The ISRO team predicted that the bomb created a cavity with a 66-metre radius and was roughly 17 times more powerful than the Hiroshima atomic explosion.
