Glide-snow avalanche characteristics at different timescales extracted from time-lapse photography
Annals of GlaciologyGlide-snow avalanches release due to a loss of friction at the snow–ground interface, which can result in large avalanches that endanger infrastructure in alpine regions.

Exploring how Sentinel-1 wet-snow maps can inform fully distributed physically based snowpack models [PDF]
The CryosphereDistributed energy and mass balance snowpack models at sub-kilometric scale have emerged as a tool for snow-hydrological forecasting over large areas.

Temporal evolution of crack propagation propensity in snow in relation to slab and weak layer properties [PDF]
The Cryosphere, 2016 If a weak snow layer below a cohesive slab is present in the snow cover, unstable snow conditions can prevail for days or even weeks. We monitored the temporal evolution of a weak layer of faceted crystals as well as the overlaying slab layers at the ...

Ecological Research, Volume 41, Issue 4, July 2026.In this study, we used ecological niche models to quantify historical changes in the estimated distribution ranges of the alpine butterfly Colias palaeno and its host plant Vaccinium uliginosum in Japan. The results showed that temperature and host plant occurrence strongly influence the estimated distribution of C. palaeno.

Thermal energy in dry snow avalanches [PDF]
The Cryosphere, 2015 Avalanches can exhibit many different flow regimes from powder clouds to slush flows. Flow regimes are largely controlled by the properties of the snow released and entrained along the path. Recent investigations showed the temperature of the moving snow

Satellite‐Based Assessment of Methane Emissions From the Darvaza Gas Crater
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Methane is a potent greenhouse gas, and the Darvaza crater in Turkmenistan is a rare, persistent emitter. There are uncertainties regarding its formation date (either 1963 or 1971), fire ignition, and the fire's influence on methane release. Using historical Landsat imagery, we reconstruct the fire history, identifying that combustion began ...

, 2001 Snow avalanches occur in many areas of Canada, mostly in remote or uninhabited locations. The few that impact society cause significant damage. Snow avalanches have killed over 570 people in Canada since the mid-1800s. Traffic delays and damage to forests cost millions of dollars annually.

Study of Free‐Space Optical Quantum Network: Review and Prospectives
Advanced Science, Volume 13, Issue 36, 29 June 2026.Free from the constraints of fiber connections, free‐space quantum network enables longer and more flexible quantum network connections. This review summarizes and comparatively analyzes free‐space quantum network experiments based on ground stations, satellites, and mobile platforms.

Towards a model of glide-snow avalanche occurrence using in-situ soil and snow measurements
Journal of GlaciologyGlide-snow avalanches release at the soil-snow interface and are currently difficult to predict. This is mostly due to a limited understanding of the release process and a lack of data, particularly of the snowpack and underlying soil conditions prior to

Calculation of Snow Avalanche Runout Distance [PDF]
Annals of Glaciology, 1983 Distance of maximum avalanche runout is calculated by four topographical factors. An empirical equation found by regression analysis of 206 avalanches is used to predict the maximum runout distance in terms of average gradient of the avalanche path (angle α).
