What is the most common trigger for avalanches?
Some common natural triggers are: Loading from new snow, wind-transported snow, or rain. Temperature changes and thawing caused by warm air and solar radiation.
What are the proper precautions for an avalanche?
Wear a helmet to help reduce head injuries and create air pockets. Wear an avalanche beacon to help rescuers locate you. Use an avalanche airbag that may help you from being completely buried. Carry a collapsible avalanche probe and a small shovel to help rescue others.

- You see an avalanche happen or see evidence of previous slides.
- Cracks form in the snow around your feet or skis.
- The ground feels hollow underfoot.
- You hear a “whumping” sound as you walk, which indicates that the snow is settling and a slab might release.
What is an avalanche chute?
A colossal mass of snow thunders down a mountainside, hurling above it an immense cloud of powdery snow. Such natural snow courses are known as avalanche chutes. Despite the avalanche’s destructive power, soil often remains along the avalanche chute, creating a new opening for pioneering vegetation.

What is a snow slide?
An avalanche (also called a snowslide) is a rapid flow of snow down a slope, such as a hill or mountain. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees.
How do humans trigger avalanches?
Human-triggered avalanches start when somebody walks or rides over a slab with an underlying weak layer. The weak layer collapses, causing the overlaying mass of snow to fracture and start to slide. Earthquakes can also trigger strong avalanches.
