Assessing snow instability in skier-triggered snow slab avalanches by combining failure initiation and crack propagation
(2017)Cold Regions Science and TechnologyDry-snow slab avalanches start with a local failure in a weak snowpack layer buried below cohesive snow slab layers. If the size of the failed zone exceeds a critical size, rapid crack propagation occurs possibly followed by slab release if the slope is steep enough. The probability of skier-triggering a slab avalanche is generally characterized by classical stability indices that do not account for crack propagation. In this study, we ...Journal Article
