In 90 percent of avalanche fatalities, the avalanche is triggered by the weight of the victim, or someone in the victim's party. Natural avalanches occur because new or windblown snow overloads weak layers of snow, or because of rapid warming, but there's almost always obvious signs of instability by the time avalanches come down on their own.
