Signatures of the sub-Rayleigh to supershear fracture transition in snow avalanche experiments [PDF]

open access: yesNature Communications
Snow 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 ...

Micromechanical modeling of snow failure [PDF]

open access: yesThe 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 ...

Granular avalanche statistics in rotating drum with varied particle roughness

open access: yesNational Science Open, 2023
We experimentally investigate the avalanche statistics of dry granular materials in a slowly rotating drum for five types of beads with varied surface roughness.

Wind tunnel experiments: cold-air pooling and atmospheric decoupling above a melting snow patch [PDF]

open access: yesThe Cryosphere, 2016
The longevity of perennial snowfields is not fully understood, but it is known that strong atmospheric stability and thus boundary-layer decoupling limit the amount of (sensible and latent) heat that can be transmitted from the atmosphere to the snow ...

The relevance of rock shape over mass—implications for rockfall hazard assessments

open access: yesNature 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

open access: yesFrontiers 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

Catastrophic avalanches on Sakhalin and the Kuril Islands (1910–2020)

open access: yesЛëд и снег, 2022
Sakhalin Island and the Kuril Islands are among the most dangerous regions in Russia in terms of the impact of avalanches on the population and economics.

Snow Avalanche Hazard Mapping Using a GIS-Based AHP Approach: A Case of Glaciers in Northern Pakistan from 2012 to 2022

open access: yesRemote Sensing, 2023
Snow avalanches are a type of serious natural disaster that commonly occur in snow-covered mountains with steep terrain characteristics. Susceptibility analysis of avalanches is a pressing issue today and helps decision makers to implement appropriate ...

Mountain protective forests under threat? an in-depth review of global change impacts on their protective effect against natural hazards

open access: yesFrontiers in Forests and Global Change, 2023
Forests in mountain areas provide an indispensable ecosystem service by protecting people and infrastructure against natural hazards. As forests are increasingly affected by global change, including climate change, more frequent and severe natural ...

Snowpack and avalanche characterization over the 2021–2022 winter season in Sisimiut, West Greenland

open access: yesFrontiers 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.
