it is caused when rapid temperature changes occur, a heavy snow fall, or strong winds. Skiers or snowboarders also set off avalanches because they will ski on the fresh loose snow and if the conditions are right the snow will crack beneath them. Loud noises do not set off avalanches. If you don't believe me look up "Avalanches 101" on YouTube.com or nationalgeographic.com
