A blast wave travels faster than the speed of sound, and the passage of the shock wave usually lasts only a few milliseconds. Like other types of explosions, a blast wave can also cause damage to things and people by the blast wind, debris, and fires. The original explosion will send out fragments that travel very fast.
An idealized shock tube. The plot shows different waves which are formed in the tube once the diaphragm is ruptured. A shock tube is an instrument used to replicate and direct blast waves at a sensor or model in order to simulate explosions and their effects, usually on a smaller scale. Shock tubes (and related impulse facilities such as shock ...
The initial version was created in February 2012, with major upgrades in July 2013, [2] [3] [4] which enables users to model the explosion of nuclear weapons (contemporary, historical, or of any given arbitrary yield) on virtually any terrain and at virtually any altitude of their choice. [5]

The Bombing Islands [b] is a puzzle video game developed and published by Kemco for the PlayStation.It was later re-released for Nintendo 64 as Charlie Blast's Territory (whose working title was Charlie Blast's Challenge [4]) in 1999 in North America on April 2, and in Europe on June 18. [3]
This phenomenon of a blast wave occurs when the blast reaches the ground and is reflected. Below a certain reflection angle the reflected wave and the incident wave merge and form a reinforced horizontal wave; this is known as the 'Mach stem' (named after Ernst Mach ) and is a form of constructive interference and consequently extends the range ...
The team used advanced computer modelling to study how a nuclear blast wave speeds through a standing structure. Their simulated structure featured rooms, windows, doorways, and corridors and allowed them to calculate the speed of the air following the blast wave and determine the best and worst places to be.
The duration of the blast wave depends on the type of explosive material and the distance from the point of detonation. The blast wave progresses from the source of explosion as a sphere of compressed and rapidly expanding gases, which displaces an equal volume of air at a very high velocity. The velocity of the blast wave in air may be ...
