Devastating Avalanche!

As you can see here an avalanche from the top mountains has occured. an avalanche occurs when a mass of snow falls down a mountainside. This happpens because new dry snow accumulates on a more heavy snow layer. Since the new snow layer is not compact, it could slide down toward the base of the mountain. Avalanches can be triggered by loud noise (yells, firearm shots, etc.). Skiers, snowboarders and climbers could also cause an avalanche. There are two ways to reduce avalanche risks: by installing snowsheds or by triggering controlled avalanches. These protection fences are made of rocks, soil and other materials. They prevent avalanches to fill trails used by humans. Controlled avalanches cause the accumulated snow to fall down before it could trigger avalanches by itself. When nobody is in danger, explosives are used to produce a loud noise that causes an avalanche.Avalanches could be seen every winter in mountainous regions of Québec. Fortunately, they do not often occur near inhabited areas.
