What are the three primary causes of death in avalanches?

The correct response identifies asphyxia, trauma, and hypothermia as the three primary causes of death in avalanches.

Asphyxia occurs when a person is buried under snow, leading to an inability to breathe. The snow can block the airway or create a situation where the individual is unable to move their head to the surface, resulting in suffocation. This is the most common cause of death in avalanche victims and highlights the critical need for timely rescue efforts.

Trauma is another leading cause, as avalanches can sweep individuals over rough terrain, causing blunt force injuries upon impact with rocks, trees, or ice. These injuries can be severe and, in many cases, lead to fatalities.

While hypothermia can be a significant factor, especially if a person is trapped under snow for an extended duration, it is less immediate as a cause of death compared to the direct effects of asphyxia and trauma during an avalanche scenario.

Recognizing the interplay of these factors is essential for both prevention and effective rescue operations in avalanche situations.
