Signatures of the sub-Rayleigh to supershear fracture transition in snow avalanche experiments [PDF]
Nature CommunicationsSnow slab avalanches occur when a crack propagates within a highly porous weak snow layer buried beneath a cohesive snow slab. Here, we report direct observations of a supershear event in snow fracture experiments following the spontaneous transition ...

The relevance of rock shape over mass—implications for rockfall hazard assessments
Nature Communications, 2021 The awareness of rock shape dependence in rockfall hazard assessment is growing, but experimental and field studies are scarce. This study presents a large data set of induced single block rockfall events quantifying the influence of rock shape and mass ...

Effects of Climate Change on Avalanche Accidents and Survival
Frontiers in Physiology, 2021 Avalanches are major natural hazards in snow-covered mountains, threatening people and infrastructure. With ongoing climate change, the frequency and types of snow avalanches may change, affecting the rates of avalanche burial and survival. With a wetter

Snowpack and avalanche characterization over the 2021–2022 winter season in Sisimiut, West Greenland
Frontiers in Earth Science, 2023 In Greenland, snow avalanches have been recognized as a significant hazard and a risk to communities for decades. However, prior to this study, no formal avalanche database nor avalanche forecasting service existed in Greenland.

Micromechanical modeling of snow failure [PDF]
The Cryosphere, 2020 Dry-snow slab avalanches start with the formation of a local failure in a highly porous weak layer underlying a cohesive snow slab. If followed by rapid crack propagation within the weak layer and finally a tensile fracture through the slab, a slab ...
