1. What parts of the world are most vulnerable to assigned hazard.
A: Internationally, the Alpine countries of France, Austria, Switzerland, and Italy experience the greatest number of avalanches and loss of life annually.
2. Why there? What physical and human processes have increased the vulnerability of those locations?
A: Mountainous areas throughout arctic and temperate regions which have slope angles between 25oC and 60oC are at risk. However, other conditions may affect the likelihood of an avalanche being triggered as already mentioned. The avalanche problem is more severe in Europe than North America due to the higher population densities in the Alp mountain range.
3. What are the costs in life and property?
A. 3. Avalanche disasters from 1980 - 2008

4. How did people in vulnerable locations adapt to the threat and prepare for the event?
A. By banning buildings in avalanche chutes and other danger zones, erecting large walls outside resorts towns to protect them form avalanches, covering roads with reinforced roofs.
5. Interesting fact about Avalanches?
A. An avalanche is often triggered when a person’s body weight provides just enough extra stress to collapse the weaker layer below.
