Amazing Avalanche in Austrian Valley

White stream of snow flows through the beautiful landscape in a valley in Austria. Check out the moving snow! This is a wet snow avalanche, a low velocity suspension of snow and water, with the flow confined to the track surface. Most avalanches occur spontaneously during storms under increased load due to snowfall. The second largest cause of natural avalanches is metamorphic changes in the snowpack such as melting due to solar radiation. Other natural causes include rain, earthquakes, rockfall and icefall. Artificial triggers of avalanches include skiers, snowmobiles, and controlled explosive work.
