Overpressure (or blast overpressure) is the pressure caused by a shock wave over and above normal atmospheric pressure. The shock wave may be caused by sonic boom or by explosion , and the resulting overpressure receives particular attention when measuring the effects of nuclear weapons or thermobaric bombs .
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
For example, Ibolja Cernak, a leading researcher in blast wave injury at the Applied Physics Laboratory at Johns Hopkins University, hypothesized, "alterations in brain function following blast exposure are induced by kinetic energy transfer of blast overpressure via great blood vessels in abdomen and thorax to the central nervous system."

While many dog owners know that giving Fido chocolate can causing poisoning, there other lesser known foods that need to be kept away from your dog. 9 types of food you should never feed your dog ...
Bomb Power Indicator, also known by the acronym BPI, was an instrument built to detect nuclear explosions and measure the peak overpressure of their blast waves. It was used at the twenty five British Royal Observer Corps (ROC) controls and nearly 1,500 ROC underground monitoring posts, across the United Kingdom during the Cold War .
An overpressure event is a sudden increase in atmospheric pressure caused by the shock wave from an explosion or, in the case of Starship ... Study: Sonic booms from SpaceX launches could cause ...
A blast wave phenomenon is an incident involving the violent release of energy created by detonation of an explosive device. The sudden and intense pressure disturbance is termed the “blast wave.” The blast wave is characterized by an almost instantaneous rise from ambient pressure to a peak incident pressure (Pi).
