Root Cause

Avalanche debris moves like a fluidized mass; swimming or rolling is ineffective because the snow is too dense and turbulent, and victims are quickly buried regardless of their movements.

中文

雪崩碎屑像流化体一样运动；游泳或侧滚无效，因为雪太密且湍急，无论受害者如何移动都会被迅速掩埋。

Workarounds

  1. 90% success If caught, deploy an avalanche airbag backpack immediately (pull handle). Airbags increase buoyancy and reduce burial depth by keeping victim near the surface.

  2. 50% success Perform the 'avalanche swim' technique correctly: try to move to the side of the avalanche (not against flow) and create an air pocket in front of your face as the snow slows. Use one hand to clear space.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Spreading limbs increases surface area but also increases torque, causing tumbling and disorientation

  2. 90% fail

    Avalanche snow moves at 80-200 km/h; jumping is impossible due to force and disorientation

  3. 85% fail

    Poles and axes are ripped from hands instantly; attempting to anchor increases injury risk from impact with rocks/trees
