Snow or ice that slides down a steep slope at great speed. Avalanches occur when the force of snow on the surface is formed under the influence of heavy snowfall, rapid melting of snow, rainfall, recrystallization of a loose layer of snow with a deepening. According to the nature of the landslide, it is divided into landslides, troughs and landslides. During an avalanche of dry snow, a wave of air appears in front of it, which has time to spread. Avalanches follow their former trampled path, the lake. 2 million m3, and the impact force is up to 60 - 100 t / m3. In landslide-prone mountains (Ili, Semirechye Alatau, etc.) avalanche protection systems (snow shields, artillery shelling of dangerous slopes, etc.) are established, deforestation is prohibited. Trees will be laid on landslide-prone slopes. Avalanches are caused by the collapse of vertical hanging glaciers and their downward movement.
