In the Alpine regions avalanche danger: especially new snow and Wind cause problems. The typical types of Avalanches.
The snow Board avalanche
it occurs on Slopes 30 to 45 degrees of inclination, where, often, skiers and snowboarders are on the go. Prerequisite for you is that snow different snow periods, is located on top of each other. In addition, must compact the snow of the upper layer to a Board. This happens, for example, by Wind during a snowfall.
Forms of an older, more underlying layer of snow and then crystals, one speaks of a “weak layer”. This can break due to an additional load; the extra snow, which increases the pressure on this layer is sufficient. The fracture propagates in a matter of seconds in all directions, a large snow Board dissolves and goes out. This avalanche can also be triggered if the break occurs there and upwards is spreading.
