And how does an avalanche occur,well in general they happen by vibrations caused by movement of the earth such(prenominal) as anearthquake, gunfire, rainy weather, and many more.Now I would like to talk a little about past avalanches and landslips that haveoccurred like the 1903 Frank landslide and avalanche that happened at the sametime, in Alberta Canada it destroyed the parks canyons its fine treesits wonderful sights and killed nearly hotshot hundred people, and covered a nonagedtown near Alberta with ice and snow.Another devastating avalanche incident is the 1964 Sherman slide, in which ahuge avalanche wa s triggered by the 1964 Alaskan earthquake. The slide spilledout onto the Sherman glacier, during the big slide several other smaller slideshappened and those were the one that took lives in Anchorage, and destroyedpropertyThere are a join of types of avalanches and how the destroy so much this oneis named "Loose Snow Avalanches"1, it starts in a small area then grows in sizeand mass as it descends.Another type is the "Slab Avalanche" it actually startsin a large area of ice and snow and then begins to slide.On September 12 of 1717 crusaded down the Troilet, Italy glacier, gaining speedon a cushion of air orbit a falling velocity of km/hr over a 3600 m fall.Two towns were destroyed, with seven people killed and a 120 cattle lost. Theslosh of an avalanche ran up the far side of the valley at a speed of 125 km/hr.In developed areas such as ski resorts it is possible to predict avalanchesbecause they are controlled with explosives and artillery. In a keep going-coun tryareas it is possible to predict avalanches because the forecast relies onexperience of the person reservation the observation. There are no computer modelsavailable to predict avalanches and thereof predictions are only accomplishedby repetitive observations and knowledge of snow properties.Due to difficulty in reliable predictions method areas of avalanche hazards essentialrely on controlling or altering the effects of an avalanche.The back country explorer must be highly skilled in determining safe routes andrescue procedures over and above relying on predictions of avalanches for face-to-face safety.Avalanches kill people many ways but the most parking area cause of death is
