Avalanches: A Deadly Threat
What are Avalanches?
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be triggered spontaneously by factors such as heavy snowfall, wind, or earthquakes, or they can be triggered by human activity, such as skiing or snowboarding.
The Dangers of Avalanches
Avalanches are a major hazard in mountainous areas. They can cause widespread damage and loss of life. In the United States, avalanches kill an average of 25 people each year. Avalanches can occur at any time of year, but they are most common in the spring and winter months.
