| Abstract: | Abstract A powder avalanche moved a 3,200 kg truck 19,8 m horizontally and dropped it 15 2 m into a gully without serious damage. Data from the site are used to compute the velocity of snow-free air and of a snow-air mixture necessary to cause this event. These velocities are found to be within the velocity of the avalanche as estimated from the equations published by A. Voellmy. |
