3.1. EXPLOSION EVENTS
An explosion is defined as an event that results in a rapid increase in volume and release of energy in all extreme manner. Explosions can be caused by cataclysmic event like a volcanic eruptions or man made explosions like nuclear, chemical or bomb blasts [12]. The effects caused by all sorts of explosions discussed are fairly same the outcomes of the explosions are blast waves which result in the ground vibrations generating high pressures in the near atmosphere. A blast wave is defined as the pressure and flow resulting from the deposition of a large amount of energy in a small very localized volume {13} High explosives, which detonate, generate blast waves The monitoring of these vibrations and measuring of these blast waves is done by an instrument called Seismometer (discussed ill Section 3.2)
