Avelanche control What is avalanche control Avalanche control is an artificial act of triggering an avalanche to prevent large avalanches mainly through explosives with a place with lots of snow. Artificial avalanche triggering Artificial avalanche triggering is done often and common in Switzerland, this prevents collapse in transport routes, protects communities and winter sports resorts. How is this act done? The process works by detonating an explosive in the starting zone, this induces shockwave and imposes an additional load on the snowpack. This pressure initiates a crack in the weak layer of snowpacks and pushes the snow down. Explosives used 1. 2. 3. 4. by bombing from a helicopter shelling with a howitzer recoilless rifle air gun.
