NEW YORK (AP) — The crowd deaths at a Houston music festival added even more names to the long list of people who have been crushed at a major event. (for this news, please refer to this thread: https://sgtalk.net/Thread-At-least-eight...c-festival )

......

HOW ARE PEOPLE DYING IN THESE EVENTS?

They’re often getting squeezed so hard that they can’t get any oxygen. It’s usually not because they’re getting trampled.

When a crowd surges, the force can be strong enough to bend steel. It can also hit people from two directions: one from the rear of the crowd pushing forward and another from the front of the crowd trying to escape. If some people have fallen, causing a pileup, pressure can even come from above. Caught in the middle are people’s lungs.

WHAT’S IT LIKE TO BE SWEPT IN?

......

asphyxiation was listed as an underlying cause in the vast majority of the deaths. Other listed causes included “inhalation of stomach contents.”

......

were getting pressed so hard into perimeter fencing that their faces got distorted by the mesh

......

“Survivors described being gradually compressed, unable to move, their heads ‘locked between arms and shoulders ... faces gasping in panic,’” the report said. “They were aware that people were dying and they were helpless to save themselves.”

WHAT CAUSES SUCH EVENTS?

......

First is the design of the event, including making sure that the density of the crowd doesn’t exceed guidelines set by the National Fire Protection Association and others. That includes having enough space for everyone and large enough gaps for people to move about.

......

set up pens around stages in order to break large crowds into smaller groups. That can also allow for pathways for security officers or for emergency exits.

WHAT ARE OTHER CAUSES?

The crowd’s density may be the most important factor in a deadly surge, but it usually needs a catalyst to get everyone rushing in the same direction.

A sudden downpour of rain or hail could send everyone running for cover, as was the case when 93 soccer fans in Nepal were killed while surging toward locked stadium exits in 1988. Or, in an example that Still said is much more common in the United States than other countries, someone yells, “He has a gun!”

Surges don’t always happen because people are running away from something. Sometimes they’re caused by a crowd moving toward something, such as a performer on the stage, before they hit a barrier.

......

WHY AREN’T PEOPLE CALLING THIS A STAMPEDE?

Professionals don’t use the words “stampede” or “panic” to describe such scenarios because that can put the blame for the deaths on the people in the crowd. Instead, they more often point at the event’s organizers for failing to provide a safe environment.
