This was the greatest underground nuclear test in the history. It happened in the Chanikin Island which belongs to the archipelagos of Alaska. The explosion was produced by a 5 megaton warhead, which was placed about 2 kilometres below the ground. (Exactly 333 Hiroshima blast) The explosion happened deep enough to not cause a viewable explosion on the surface but lifted up the ground of the island with 7 metres in a 1,5 km area.
