Types of avalanches
An avalanche can crawl downhill at speeds of up to 300 km/h or just a few millimeters a day.
In any case, forces can develop that can uproot trees and crush houses.
There are different types of avalanches and which one ultimately develops depends on various factors.
These include the shape of the edge, the track and the way an avalanche moves, the snow conditions and the weather conditions.
