Most commonly, avalanches kill you through trauma – broken bones, internal bleeding etc. You’re being thrown off cliffs, bounced off rocks, crushed and hit by bits of snow and ice. As they breathe, this air pocket will gradually be replaced with the CO2 they expel, which will be what kills them.
What are the dangers of an avalanche?
Very steep, extreme terrain is especially unfavourable as regards the slope angle, topography, proximity to ridgelines or ground conditionsextremely steep: steeper than 40°very steep: steeper than 35°steep: steeper than 30°moderately steep: less than 30°.
The most frequent answer is; they are common on steep slopes and are seen after a fresh snowfall. Loose Snow Avalanches in turn could cause a Slab Avalanche, which are characterized by a the fall of a large block of ice down the slopes.

There is no one reason behind the development of avalanches. Effects of Avalanches. As such, there is little damage to the overall ecological system due to avalanches.
The Avalanche Breakdown and Zener Breakdown are two different mechanisms by which a PN junction breaks. The Zener and Avalanche breakdown both occur in diode under reverse bias. The avalanche breakdown occurs because of the ionisation of electrons and hole pairs whereas the Zener breakdown occurs because of heavy doping.
Utah Avalanche Forecasters are warning a persistent weak layer But experts urge caution for backcountry users, as the snowpack is shaping up like last year’s — one of the deadliest on record. The October snowfall seemed like a blessing to those.
What should you do in an avalanche?
