When the snow on the hillside slides, it sometimes flows slowly like a pile of cement that has not yet solidified, and occasionally it is blocked by obstacles. avalanche.
Avalanche Occurrence
Usually an avalanche erupts from the top of a mountain, pushing it in front of it with great speed and great force as it moves down the mountain swept away everything, until its power was lost on the vast plains. This “white death” can weigh millions of tons. The secret to the destructive power of an avalanche is that the snow flow can drive the air wave in front of it, and the impact of this air wave is more dangerous than the blow of the snow flow itself. It can knock down houses, break trees, and suffocate people to death. It is very dangerous to encounter an avalanche. Those who are active in the snow must pay attention to the following points:
·Do not go up the mountain just after heavy snow, or after several consecutive snowfalls. At this time, the newly fallen snow or the upper layer of snow is very unstable, and a slight disturbance, even a cry, is enough to trigger an avalanche.
· When the weather is cold and warm, the weather turns sunny, or when the snow begins to melt in the spring, the snow pack becomes very unstable and prone to avalanches.
·Do not move on steep slopes. Because avalanches usually move downward, on a 1:5 slope, an avalanche can occur.
·If you must cross slopes, do not act alone or in groups, go one after the other, and the last person to leave should remain observably safe from the previous one distance.
·Watch for signs of avalanches, such as ice cracking or a low roar, a snowball rolling down, or looking up at a mountain for a cloud of grayish-white dust.
·Avalanches can be identified by topographical features such as cliffs, smooth terrain, or faults on hillsides with few trees.
Escape from avalanche
In any event, you must stay out of the avalanche route immediately.
· Judge the situation at that time. Out of instinct, it will run straight down the mountain, but the snow and ice also fall down the mountain. And the speed reaches 200 kilometers per hour. Running down is dangerous and may be buried in ice and snow.
· It is safer to run sideways, so that you can avoid avalanches or run to a higher place.
· Throw away all bulky items such as backpacks, skis, ski poles, etc. With these objects, it will be more difficult to move around if you get stuck in the snow.
·Never ski to escape. However, if you are on the edge of the avalanche route, you can drive out of danger.
· If you are caught by an avalanche and cannot escape, remember to keep your mouth closed to avoid suffocation by ice and snow pouring into your throat and lungs.
·Hold on to anything solid on the side of the hill, such as standing rocks. Even if you fall into it for a while, the ice and snow will eventually drain away, and then you can escape.
·If you’re rushing down a hill, try to climb up to the surface of the snowdrift as much as possible, while diving, backstroke, or dog crawl up the current to escape to the edge of the snow stream.
·You may have to block rocks and ice with both hands when going upstream, but be sure to try to climb up to the surface of the snowdrift.
