2020 Frank Techel, Karl Birkeland, Doug Chabot, Jim Earl, Ivan Moner, and Rob Simenhois the avalanche review #39.1| winter 20/21 Summary Since its introduction in 2006, the Extended Column Test (ECT) has become one of the most popular tests to assess point snow instability. In 2009, two studies explored how ECT results correlated to observed instabilities, laying the foundation for…

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

2020 Frank Techel, Kurt Winkler, Matthias Walcher, Alec van Herwijnen, and Jürg Schweizer Nat. Hazards Earth Syst. 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…
