Weapons of Mass Destruction
Definition
1. A weapon that can kill large numbers of humans
2. cause great damage to man-made structures, natural
structures, or the biosphere in general.
3. The scope and application of the term has evolved and
been disputed, often signifying more politically than
technically.
4. Coined in reference to aerial bombing with chemical
explosives, it has come to distinguish large-scale
weaponry of other technologies, such as chemical,
biological, radiological, or nuclear.
The term Weapons of Mass Destruction (WMD) refers to weapons that have the
capacity to kill indiscriminately on a large scale and have enormous destructive
capability. Broadly there are three main types of WMDs: nuclear weapons, biological
weapons, and chemical weapons. These weapons, if used, have the ability to
annihilate whole cities and wipe out entire populations. Non-military targets are not
exempt from the horrors of these weapons. The most vulnerable sectors of a
population, i.e. civilians and non-combatents , are always the most affected by WMD
attacks. This can be seen in the dropping of nuclear bombs in Hiroshima and
Nagasaki in 1945.

Nuclear Weapon Effects
The dominant effects of a nuclear weapon
where people are likely to be affected (blast
and thermal radiation) are identical physical
damage mechanisms to conventional
explosives. However the energy produced by a
nuclear explosive is millions of times more
powerful per gram and the temperatures
reached are briefly in the tens of millions of
degrees.

Hiroshima and Nagasaki
During the final stages of World War II in 1945, the United States conducted two atomic
bombings against Japan in the cities of Hiroshima and Nagasaki.

Earthquake
The pressure wave from an underground
explosion will propagate through the ground
and cause a minor earthquake . Theory suggests
that a nuclear explosion could trigger fault
rupture and cause a major quake at distances
within a few tens of kilometres from the shot
point.
Destruction is easy but construction is hard
