Avalanche Safety and Awareness

Avalanches are rapid snow slides that can cause significant destruction. They form when snow layers build up and weak bonds create instability. Triggers include heavy snowfall, wind, and temperature changes. Most avalanches are caused by human activity, not loud noises. Safety measures include monitoring slopes and using explosives to prevent large avalanches. Awareness and preparedness are crucial for safety.
