An avalanche is a significant amount of snow that falls 20 to 30 m. Snowfall often occurs in the form of side effects of radio waves before snowfall and causes the greatest damage. Avalanches can cause the same damage as a natural disaster, as a result of which people will die (especially among climbers, skiers) and significant material damage will be caused. Avalanches are dangerous for humans with their large size (sometimes up to hundreds of tons), leading to the death of broken bones, as well as shortness of breath or weakness. Spirit and the victim died suddenly. oxygen (suffocation). Otherwise, an avalanche can knock a person down and kill him if he falls.
The snow on the slope, which fell in the form of rain, continued to roll. How are avalanches occur? Its value depends on the moisture content of the snow, the slope. When the force of the weight of the snow begins to break the force of friction, an avalanche falls.
Slopes with a slope of 25–45 ° are more suitable for avalanches, but avalanches are known to occur with a slope of 15–18 °. In addition, avalanches sometimes descend from very gentle slopes – 10-15 °. On slopes above 50 °, snow does not accumulate in large quantities and falls in small doses to reach it, however, slopes created by avalanches are considered heavier than 15 ° or 60°.
For example, on a slope of 15 ° with a snow height of 15 cm, it is believed that under certain conditions, early spring melts and there will be strong sunlight, the snow will begin to melt. .. From strong ice. After skiing, the snow crosses the ice.
Causes of avalanches a decrease in the amount of snowfall from the slope is usually caused by weather factors: severe climatic changes (including changes in atmospheric pressure, humidity), rain, heavy snowfall, as well as the mechanical impact on snow-covered areas, including rock damage, erosion, etc.
The avalanche is caused by various factors. First of all, the slope must have a solid ice cap. When stability is disturbed by the active melting of heavy ice, snow, and rain, landslides occur across the entire surface of the slope, causing the ice blocks to crack and fall freely. Even the slightest vibration can cause loud noise and skiing and avalanches. Severe landslides can lead to strong gusts of wind and higher temperatures. Airplanes are a dangerous natural phenomenon and are widespread in Russia. Dozens of avalanches occur annually in the North Caucasus, Sakhalin, Kamchatka, Transbaikalia, and Khibiny. The famous collapse of the Khibiny avalanche: On December 5, 1935, two landslides on Mount Yuspor caused serious damage to the mining village and killed 88 people.
By the way, the weight of the ice block is increasing, creating a new direction. Why do avalanches happen Some weigh from tens to hundreds of tons? In rare cases, ice not only melts but exists and freezes. Then it reaches a total weight of tens of thousands to thousands of tons.
In rural areas, it snows most of the time, especially during high peaks, including in summer. Therefore, avalanches are formed there. In winter, the amount of snow can increase. This increases the load, causing a certain mass to vibrate at the center of the slope and gradually increase. Avalanche is a natural process.
In most cases, the reason is common. However, rescuers warn that avalanches occur and then people decide to go to the mountains during a snowfall, this can be dangerous. However, up to the snow mass, slight mechanical stress can occur.
Heavy snowfall causes and increases the level of humidity due to human factors (mechanical collisions, loud noises, gunshots, etc.), which leads to more serious earthquakes (mountains, often found in vulnerable places, seismic captains).
Therefore, it is recommended to stay only in designated areas. In addition, there are days when going downhill is dangerous because there is a lot of snow in the ski resorts.
