And how does an avalanche occur,well mainly they happen by vibrations caused by movement of the earth such as anearthquake, gunfire, rainy weather, and many a(prenominal) more.Now I would like to talk a little ab bug out past avalanches and landslides that haveoccurred like the 1903 postmark landslide and avalanche that happened at the sametime, in Alberta Canada it destroyed the parks canyons its beautiful treesits wonderful sights and killed nearly one hundred people, and covered a miniaturetown near Alberta with ice and snow.Another devastating avalanche incident is the 1964 Sherman slide, in which ahuge avalanche was triggered by the 1 964 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 couple 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 reaching a falling velocity of km/hr over a 3600 m fall.Two towns were destroyed, with seven people killed and a 120 cows lost. Theslosh of an avalanche ran up the far side of the valley at a speed of 125 km/hr.In genuine areas such as ski resorts it is possible to predict avalanchesbecause they are controlled with explosives and artillery. In a back-countryareas it is possible to p redict avalanches because the forecast relies onexperience of the person devising the observation. There are no computer modelsavailable to predict avalanches and therefore predictions are only accomplishedby repetitive observations and knowledge of snow properties.imputable to difficulty in reliable predictions method areas of avalanche hazards mustrely 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 forpersonal safety.Avalanches kill people many ways but the most common cause of death is
