Facts on Avalanche Natural Disasters
An avalanche occurs when snow slides down a mountainside, creating a path of destruction in its wake. According to the National Snow and Ice Data Center website, avalanches kill an average of 150 people each year around the globe.

Size

The worst avalanche of modern times occurred in Yungay, Peru, in 1970 when an estimated 20,000 individuals perished as the force obliterated their village. The avalanche was a mile wide and 10 miles in length and happened in the Andes Mountains.

History

Avalanches in the Alps during the time of Hannibal, around 218 B.C., reportedly killed thousands of soldiers while an avalanche that occurred in 1618 in Plurs, Switzerland, killed 2,427 citizens.

Cause

The Swiss, Italian and Austrian Alps were the scene of frequent fatal avalanches as a result of the high amounts of precipitation during the incredibly snowy winter of 1950 through 1951, with over 265 people dying in these events.

On March 1, 1910, an avalanche claimed the lives of 96 railway passengers in Washington State's Cascade Mountains when it swept a pair of trains off the tracks and into a ravine.
