Stampede

From Wikipedia, the free encyclopedia

A stampede is an act of mass impulse among herd animals or a crowd of people in which the herd (or crowd) collectively begins running with no clear direction or purpose. Stampedes are believed to originate from biological responses in the brains and endocrine systems of herd animals. The response is believed to have evolved to help animals escape predators.

A large stampede will frequently destroy anything in its way. In farmed animals, herd managers, sometimes called cowboys, attempt to turn the moving herd into itself, so that it runs in circles rather than self-destructing by running over a cliff or into a river, or from damaging human life or property by overrunning human settlements.

Specific animals associated with stampede behaviour are cattle, elephants, Blue Wildebeests and wild horses.

[edit] Human stampedes

The term stampede, also known as a crush or trampling, commonly describes a sudden rush of a crowd of people, usually resulting in many injuries and death from suffocation and trampling. Human stampedes most often occur during religious pilgrimages and professional sporting and music events. They can also occur as a result of another problem such as a fire, as people try to move away or escape.

The annual Muslim Hajj in Mecca, Saudi Arabia, which is attended by millions of pilgrims, has increasingly suffered from stampedes and other disasters, even as authorities have constructed new walkways and instituted other traffic controls to prevent them. The worst documented stampede in modern history happened at the 1990 Hajj, when over 1400 people died in a tunnel.

While it may seem that shorter people are at greater risk for injury during a stampede, this is not the case. Taller people, while stumbling and tripping over everybody else, are more likely to be knocked down and trampled.[citation needed] The elderly and very young are especially prone to injury or death during a stampede because of their frailty, disabilities, size, or weakness.

Very often people away from the location of the crush or trampling are completely unaware of the problem.
