What do you suppose causes most avalanches to occur?
Snow avalanches are most likely to occur after a fresh snowfall adds a new layer to a snowpack If new snow piles up during a storm, the snowpack may become overloaded, setting off a slide Earthquakes can set off avalanches, but much smaller vibrations can trigger them as well

What kills you in an avalanche?

Can you breath under snow?
Breathing under snow, eg while buried by a snow avalanche, is possible in the presence of an air pocket, but limited in time as hypoxia and hypercapnia rapidly develop Snow properties influence levels of hypoxia and hypercapnia, but their effects on ventilation and oxygenation in humans are not fully elucidated yet
