A major collective stampede occurred in Itaewon, South Korea, which has caused 156 deaths and 151 injuries to .

On the evening of the 29th, there were tens of thousands of people crowded in Itaewon in Seoul, South Korea to participate in the Halloween event !

is strange and it is time to report that more than 24,100 people were missing? ...

Why is that person missing? Is it not confirmed that death? Or was it taken away by the squeezed and twisted space? Maybe it was just that the family members were too worried and had no contact, so they reported missing in a hurry!

But how could such a small alley be squeezed to death by hundreds of people? What is the reason? A dead end?

First of all, use Li Yongle teacher’s blackboard writing to explain the environment of this alley!

This is a small alley where people from three directions gather. It is said that someone shouted ***The famous IDOL is coming, and it is crowded with people, squeezing into such a narrow alley!

What is the alley? It is a 3.2-meter-wide alley with more than 300 people crowding into a length of 5.7 meters, with an area of only 18 square meters!

From the picture above, we can also see that there is a slope in the alley, about six degrees!

Then how can you squeeze people to death? Then we need to explain the reasons for this trampling:

The first is the arch phenomenon, to put it bluntly, it is the funnel phenomenon. Suddenly, a large number of glass beads are imported into the funnel, and the bottom of the funnel will be blocked, and the more it falls, the faster it will be blocked! This is similar to the principle of blocking the toilet. You said I didn’t pour anything big, why did it get blocked? It’s just that multiple small objects were squeezed into the small passage. The more you flushed the water, the more honest it was. This is just like the scene in Itaewon!

The second reason is that there is an antagonistic cluster; is just blocked, and the direction of people's movement is still inconsistent. Without command, this space is filled! In this way, the force generated inside is evenly dispersed, so the police can't pull it out after they come. This is just like the text "A Successful Experiment" I learned when I was a child, three iron balls cannot come out of the bottle at the same time!

Finally, there is a heterogeneous cluster: In an emergency, people want to surpass those who walk slowly and block their own movements, want to get out of the squeezed crowd, and thus pull and push!

How did that person die?

fell to the ground and stepped on it. The density of the crowd caused many people to form a semi-empty state, so their judgment on the ground was very vague, so they would unconsciously walk while walking on people!

Then it is squeezed. has a relatively stationary squeeze for a long time. To put it bluntly, it is because someone is squeezed in the middle and becomes a group of people. Moving forward for a long time, it causes blood oxygen to drop and coma and then continues to maintain it and die of suffocation!

At the same time, there are too many illegal buildings around Itaewon shops, which has had a great impact on traffic, which is also a very important reason!

What is "Itaewon"? Itaewon's predecessor was a US military base station in South Korea. Now, the most important military base in South Korea, "Rongsan Base", is adjacent to Itaewon. Itaewon is also known as " alien-fat ". Later, due to its indecent name, it was homophonic to "Itae". As we all know, wherever the US military is stationed, the pornography industry around must be very developed, such as Japan, Thailand, , Philippines, and South Korea. In order to meet the sexual needs of a large number of American soldiers, many Korean girls come here to be prostitutes or mistresses. Over time, these Korean girls and white Americans and black soldiers gave birth to many mixed-race children, which was unacceptable in a single-ethnic South Korea, so they called this place a "single-fatal hospital".So it is also unique to hold the "Ghost Festival" here! How can you avoid trampling and save yourself if you happen to trampling?

. Don’t go to places where there are too many people, especially activities that are too crazy

. When you see a large number of people, you should hide in nearby buildings

. If you are brought in by a crowd, you must walk diagonally in front of the flow, so that you can easily get out of the crowd

. To avoid falling, you can find some railings that you can grab or climb to a high place

. Never lean your body, and don’t bend over and tie your shoelaces. This is the easiest way to fall. If you fall, you can lean against the wall to protect the back of your head and neck and face to lie on the side of the wall

7. If you can’t stick to the wall, lie on your side, use your elbows to make a protective rack to protect your head, neck and chest and make your breathing smoothly!
