  2. Definition &Howdeadly aAvalanche is. Definition The definition of an avalanche is. A large mass of snow, ice, etc., detached from a mountain slope and sliding or falling suddenly downward.

  3. Where does an Avalanche Occur Avalanches occur in high mountains after heavy snowfalls especially. The steeper the mountain the greater the chance of an avalanche happening. Places like the Alps in Europe, the Himalayas in Nepal/India, and the Rocky Mountains in the USA are all likely to have avalanches

  4. When does an Avalanche Occur While avalanches are sudden, the warning signs are almost always numerous before they let loose. Yet in 90 percent of avalanche incidents, the snow slides are triggered by the victim or someone in the victim's party. Avalanches kill more than 150 people worldwide each year. Most are snowmobilers, skiers, and snowboarders.

  5. What causes an Avalanche Layers of snow build up and slide down the mountain A vibration or movement like the voice of a person or a train can start and avalanche Certain weather conditions like wind and rain A rock or a piece of ice can shake the snow to slide down the mountain Water under the snow could make the snow slide A section of the snow could fall down or break apart and slide down the mountain
