Any sane person having read that the explosion occurred at a depth of 50 m and its power was 10 to 20 kilotons of tnt would immediately conclude that an explosion of such power at such a shallow depth would certainly cause a crushing tsunami wave.
Information about the alleged underwater nuclear explosion that occurred in the south china sea began to spread a couple of days ago. The overall effect of an underwater explosion depends on depth the size and nature of the explosive charge and the presence composition and distance of reflecting surfaces such as the seabed surface thermoclines etc this phenomenon has been extensively used in antiship warhead design since an underwater explosion particularly one underneath a hull can produce greater damage than an.
