Avalanches

AVALANCHES

Many factors cause an avalanche. Heavy snow is too big usually cause landslides. 

Avalanches can be triggered by natural or human activities. Landslide usually occur in mountainous areas. Avalanches can mix air and water. 

powerful avalanch

es have the ability to bring ice, rocks, trees, and other materials available on the slopes. Avalanches primarily composed of flowing snow, and different from the landslides, falling rocks, rock avalanches and debris Serac. In the mountains, avalanches are the most seriouse danger to life and property, with the capability of destroying is a result of their potential to bring great masses of snow quickly and widely spaced.

Avalanches are classified based on morphological characteristics, and assessed according  to their destructive potential or a mass of snow flowing down. Some morphological characteristic used to classify them, which is kind avalanches involved, the nature of failure, the slope surface, the propagation mechanism of the failure, the trigger avalanches, slope angel, direction, and altitude.

Size, mass, and the potential damage from a landslide assessed on a logarithmic scale, typically consist of 4 to  7 categories, with the precise definition of the categories depending on the observation system or forecast region.
