Underwater Explosions

As powerful as explosions can be above ground, they are even more dangerous underwater. Since water, unlike air, is incompressible, the pressure wave at the front of an underwater explosion is not damped to the extent it would be in air. A high-pressure, high-temperature bubble of gas also forms in the explosion, and, as with cavitation, if the bubble collapses near metal, the damage can be extensive. (via Gizmodo)
