Explosive detonations which occur underwater create shock waves in a similar manner to explosions in air. Due to the elastic properties of water, the shock wave tends to be of shorter duration, but with a proportionally larger peak overpressure. The energy in the underwater shock wave slowing very quickly with range. Therefore, the shock wave from an underwater explosion does not cause the same level of damage as one would expect from studying explosions in air. However, this is not to say that there are no effects from underwater shock waves.

The effects of an underwater explosion can be divided into two distinct phenomena: the shock wave and bubble pulsation. So, what are the differences between an underwater explosion and a blast in the air? First, while overpressure increases quickly at the shock front in air and water, it lower swiftly in an air explosion. As a result, peak values in water are substantially greater than peak values at the same distance from an equal explosion in the air. Second, in the next stand, the sound velocity in water is roughly five times that of air. As a result, it creates rapid waves in the water.
