An avalanche occurs when a mass of snow falls down a mountainside. That is because new snow (which is not wet) 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 could 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. During the winter, do not venture in the mountain without an adult. If you walk in a trail after a snow fall, do not walk in the middle of it, but rather on the side. Avalanches always fall down in the middle of the path; thus, if you are on the side, the risks of being hit by the avalanche are lower. * In 1999, an avalanche killed many people in Kangiqsualujjuaq, near the Ungava Bay in northern Québec.
The avalanches occur as a result of the snow packed mountains become to heavy to support itself and therefore fall at the base of the mountain.

What is Avalanche breakdown?

Avalanche breakdown is a phenomenon that can occur in both insulating and semiconducting materials. It is a form of electric current multiplication that can allow very large currents to flow within materials which are otherwise good insulators. It is a type of electron avalanche. The Avalanche process occurs when the carriers in the transition region are accelerated by the electric field to energies sufficient to free e- h pairs via collisions with bond electrons.
