How Blast Waves Cause Damage
Blast waves cause damage by a combination of the severe condensing of the air in front of the wave (forming a shock front) and the subsequent wind that follows. A blast wave travels faster than the speed of sound and the passage of the shock wave usually only lasts 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. Debris and sometimes even people can get swept up into a blast wave, causing more injuries such as penetrating wounds, impalement, broken bones, or even death. The blast wind is the area of low pressure that causes debris and fragments to actually rush back towards the original explosions. The blast wave can also cause fires or even secondary explosions by a combination of the high temperatures that result from detonation and the physical destruction of fuel-containing objects.

Famous quotes containing the words blast, waves and/or damage:
“Once more unto the breach, dear friends, once more,
Or close the wall up with our English dead.
In peace there’s nothing so becomes a man
As modest stillness and humility,
But when the blast of war blows in our ears,
Then imitate the action of the tiger.
Stiffen the sinews, conjure up the blood,
Disguise fair nature with hard-favoured rage.”
—William Shakespeare (1564–1616)
“What is Americanism? Every one has a different answer. Some people say it is never to submit to the dictation of a King. Others say Americanism is the pride of liberty and the defence of an insult to the flag with their gore. When some half-developed person tramples on that flag, we should be ready to pour out the blood of the nation, they say. But do we not sit in silence when that flag waves over living conditions which should be an insult to all patriotism?”
—Anna Howard Shaw (1847–1919)
“I learned early to understand that there is no such condition in human affairs as absolute truth. There is only truth as people see it, and truth, even in fact, may be kaleidoscopic in its variety. The damage such perception did to me I have felt ever since ... I could never belong entirely to one side of any question.”
—Pearl S. Buck (1892–1973)
