An avalanche can last from a few seconds to several minutes. Sometimes several avalanches take place in quick succession making it look like one big avalanche. An avalanche is triggered when several layers of snow pile up with a weak supporting layer beneath it. The snow may be fresh and powdery.

Why are there so many avalanches this year?
Experts say the uptick in avalanches has been fueled by weather conditions that create a weak bottom to the snowpack, which then becomes prone to slides. Early-season snow followed by a long dry spell in much of the Western U.S. created a persistent weak layer in the snowpack.
What state has the most avalanche fatalities?

Can yelling start an avalanche?
Abstract: It remains a popular myth that avalanches can be triggered by noise. … The pressure amplitudes caused by shouting or loud noise are at least about two orders of magnitude smaller (a few Pascal) than known efficient triggers. Triggering by sound can therefore be ruled out as a triggering option.
