| Abstract: | Investigates path geometry, total volume in release zone, and potential magnitude, based on data from 1673 avalanche surveys, aerial photo interpretations, and video observations. Slopes in release zone ranged from 35-40° and 40-45° for surface and full-depth avalanches, respectively. Frequency histograms of direct and indirect angles of elevation from outer end of deposit zone to highest point of release zone indicate normal distributions, respectively peaking in ranges 32-36° and 34-38°. Angle of elevation and coefficient of friction become smaller as total volume in release zone or potential magnitude of avalanche increases. Avalanches with >10⁵ m³ total volume in release zone are surface avalanches. Run-out distance and excess travel distance increase linearly with potential magnitude above values around seven. |
