How do tourists save themselves when they encounter an avalanche when crossing a canyon in Tibet?

Recently, a tourist passed through Bagai Township, bomi county, Tibet, and encountered an avalanche while crossing the Gong Yi Grand Canyon. The snow on the top of the mountain fell into the middle of the canyon at lightning speed. Fortunately, the tourists left quickly without causing any casualties. Later, tourists posted the video online, and many netizens marveled at the power of nature and realized the danger in the snow-capped mountains. What if we encounter an avalanche in the wild or ski on a snowy mountain? How can we save ourselves?

The main reason for the avalanche is that the snow on the hillside of the canyon is too thick. After the snow is irradiated by sunlight, the surface snow melts, and the snow water penetrates between the snow and the hillside, reducing the friction between the snow and the ground. At the same time, the snow layer began to slide under the canyon under the action of gravity. In addition to these problems, avalanches caused by a large number of snow slides may also be caused by earthquakes.

The formation and development of avalanches can be divided into three sections, namely, formation area, passing area and accumulation area. Formation area: the formation area of avalanche is mostly in the upper part of the mountain, where there is much and thick snow. For example, high snow eaves, snow slopes with a slope of more than 50 ~ 60 degrees, and the lower end of suspended glaciers are all areas where avalanches form. Passing area: The passing area of the avalanche is just below the formation area, which is generally a straight U-shaped groove from top to bottom. Because avalanches often pass by, although the ditch is covered with snow, it is still very flat, and there are basically no ups and downs or obstacles. It can be several hundred meters long, 20-30 meters wide or slightly larger, but it is not too wide. Otherwise, the falling snow and ice will not be very concentrated and will not form a big avalanche. Accumulation area: the accumulation area is also directly below the stratigraphic area, where the avalanche stops due to the sudden slowdown of the slope at the foot of the mountain. From the landform, it is mostly conical, so it is also called collapse cone.

How to save yourself in an avalanche? Run sideways in the direction of the avalanche and try to avoid the avalanche. Don't be afraid to run down the mountain, because the speed of avalanche is definitely faster than yours, and the danger of running down the mountain will increase a lot. When you find an avalanche, you must lose all your weight quickly to make it easier for you to escape. When there is no escape in an avalanche, try to find a bunker nearby and then hide behind. When there is no shelter, try to squat down and keep crawling. Try to build a bigger cave to rest yourself and leave before the snow solidifies. Keep your strength. If you hear someone passing by, shout for help, so that rescuers can find a place more easily. After being buried by snow, keep calm, try your best to climb to the surface of the snowdrift, and pay attention to the direction of excavation. ?
