Furthermore, the definitions of the danger levels, an ordinal variable,…

Sci., 20, 1941–1953, 2020 https://doi.org/10.5194/nhess-20-1941-2020 Abstract Snow instability tests provide valuable information regarding the stability of the snowpack. Test results are key data used to prepare public avalanche forecasts. However, to include them into operational procedures, a quantitative interpretation scheme is needed. Whereas…

However, as avalanche danger cannot be measured, the characterization of avalanche danger…

2018 Ben Reuter, Jürg Schweizer Geophysical Research Letters, 45, 7019–7027. https://doi.org/10.1029/2018GL078069 Abstract Snow instability is a generic term describing the propensity of a snow slope to avalanche. Inneed of a concise mechanics-based concept we suggest a framework based on failure initiation, crackpropagation, and slab tensile support. Following these three steps we modeled three metrics frommechanical data, which we…
