Vastavam web:The environmentalists, geologists had confirmed that North korea’s hydrogen bomb test had created avalanche in Punggye-ri mountain region. Geophysicist Wen Lianxing and his team at the University of Science and Technology of China in Hefei, Anhui province, said they “were confident” underground detonations were occurring underneath the mountain. They posted an analysis of data collected from more than 100 seismic monitoring sites across China. This has narrowed down the location of Pyongyang’s nuclear tests with a margin of error of just 100m. They’ve all been under the same mountain. The research comes after Kim Jong-un conducted its sixth and most powerful nuclear test on in the mountain on Sunday. North Korean state media claimed its underground test of the H-bomb is a major “game changer” and several shockwaves were recorded across the globe after the bomb’s supposed detonation.
