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.
Species associated with stampede behavior include cattle, elephants, Blue Wildebeests, wild horses, rhinoceros, and humans.
Anything unusual may start a stampede. Especially at night, things such as lighting a match, someone jumping off a horse, a horse shaking itself, a lightning strike, a tumbleweed blown into the herd, or "a horse running through a herd kicking at a saddle which has turned under his belly" have been known to cause a stampede . Cattle which have just fed, and are more spread out are also less likely to stampede.
A large stampede will frequently eliminate anything in its path. With farmed animals, 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. Tactics used to make the herd turn into itself include firing a pistol (i.e. using the noise) to make the leaders of the stampede turn.
Cowboys will sometimes sing or whistle at night to reassure the herd. Those on watch at night will often be careful not to do things which may startle the herd, but to ride a distance away first (e.g. before dismounting a horse or lighting a match) so as not to cause a stampede
Human stampedes most often occur during religious pilgrimages and professional sporting and music events. They also often occur in times of mass panic, as a result of a fire or explosion, as people try to get away.
Deaths from human stampedes occur primarily from compressive asphyxiation, not trampling. This is referred to as crowd crush. The compressive force occurs from both horizontal pushing and vertical stacking.
The annual Muslim Hajj in Mecca, Saudi Arabia, which is attended by millions of pilgrims, has increasingly suffered from stampedes, even as authorities have constructed new walkways and instituted other traffic controls to prevent them.
In India, stampedes occur regularly during Hindu religious holidays. Called "temple crushes" by the local press, they are often caused by railings giving way as pilgrims climb steep hills to reach a temple.
The worst stampede in recorded history took place in Chongqing, China, during World War II. Japanese bombing of the city on June 6, 1941, triggered mass panic at an air raid shelter, killing approximately 4,000 people, most of them by suffocation.
In 1908, a stampede caused the death of 16 children at public hall in Barnsley, South Yorkshire. It became known as the Barnsley Public Hall Disaster.
A popularly quoted cause of stampedes is "Shouting fire in a crowded theater", which has occurred in such instances as the Italian Hall disaster.
It has been claimed that most major crowd disasters can be prevented by simple crowd management strategies. Human stampedes can be prevented by organization and traffic control, such as barriers. On the other hand, barriers in some cases may funnel the crowd towards an already-packed area (e.g. Hillsborough disaster). Therefore, barriers could be a solution to prevent or the key factor to cause a stampede to happen. A key problem is lack of feedback from people being crushed to the crowd pressing behind – feedback can instead be provided by police, organizers, or other observers, particularly raised observers, such as on platforms or horseback, who can survey the crowd, and use loudspeakers to communicate and direct a crowd.
At the individual level, warning signs of a crowd crush include density of more than four people per square meter, at which each person is being touched on four sides. To avoid or escape from a crowd crush, one is advised to move sideways, particularly between swells.
