Avalanches and LandslidesOUTLINE1. a.WHAT IS AN descend OR LANDSLIDE?b.EXACTLY HOW DOES AN AVALANCHES OCCUR2. a.I TALK A LITTLE slightly PAST AVALANCHESb.PAST DEATHS FROM AVALANCHES3. a.CONCLUSION CLOSING OF MY REPORTWhat is an roll down? , well its a enormous mass of snow and ice or of earth or quiver sliding down a mountain side or a cliff. And how does an avalanche occur,well mainly they happen by vibrations caused by impetus of the earth such as anearthquake, gunfire, rainy weather, and many more.Now I would like to talk a little about past avalanches and landslides that take a shitoccurred like the 1903 Frank landslide and avalanche that happened at the sametime, in Alberta Canada it destroyed the parks canyons its beautiful treesits wonderful sights and killed nearly star century stack, and c everywhereed a smalltown near Alberta with ice and snow. some other devastating avalanche incident is the 1964 Sherman slide, in which ahuge avalanche was triggered by the 1964 Al askan earthquake. The slide spilledout onto the Sherman glacier, during the big slide several(prenominal) other smaller slideshappened and those were the one that took lives in Anchorage, and destroyedproperty on that point 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 indeed grows in sizeand mass as it descends.Another type is the "Slab Avalanche" it truly startsin a large area of ice and snow and therefore 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 furthest side of the valley at a speed of 125 km/hr.In developed areas such as ski resorts it is possible to shout avalanchesbecause they are controlled with explosives and artillery. In a back-coun tryareas it is possible to predict avalanches because the forecast relies onexperience of the person making the observation. There are no computer modelsavailable to predict avalanches and therefore predictions are only accomplishedby repetitive observations and knowledge of snow properties.Due to difficulty in certain 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 shipway but the most common cause of death is
