The passage of a strong shock wave through the human body, for example, causes serious damage due to the large instantaneous change in pressure. Explosions or explosive explosions are physical phenomena that cause a sudden release of energy. This process causes an almost instantaneous compression of the surrounding medium (for example, this overpressure wave) propagates out of the explosion radially at supersonic velocity, creating a trail of negative pressure (underpressure) that follows behind. After the negative pressure wave passes, the relative pressures return to baseline.

Overpressure (or explosion overpressure) is pressure caused by a shock wave above and above normal atmospheric pressure.
