How common are avalanches in Switzerland?

Over the past 20 years, there has been an average of 100 reported avalanches a year where people were involved. On average, 23 people die in avalanches every year, the majority (+90%) in open mountainous areas where people were off-piste skiing, snowboarding, or backcountry touring on skis or snowshoes. 

In controlled areas (roads, railways, communities and secured ski runs) the 15-year annual average number of victims dropped from 15 at the end of the 1940s to less than one in 2010. The last time anyone died in a building hit by an avalanche was in 1999.

This information is shared and used by the police, cantons, communes, mountain resorts, rescue services and other winter professionals across the country.
