Application of an Inertia Dependent Flow Friction Model to Snow Avalanches: Exploration of the Model Using a Ping-Pong Ball Experiment

open access: yesGeosciences, 2020
Snow avalanches are catastrophic phenomena because of their destructive power. Therefore, it is very important to forecast the affected area of snow avalanches using numerical simulations.

Wilson's Atmospheric Electron Accelerator: A Centennial Perspective

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract As of the time of writing this letter, we mark the centennial of Wilson's runaway electrons proposed in 1925. Owing to instrumentation limitations, Wilson and his students could not detect the particles anticipated by theory Chilingarian et al. (2025, https://doi.org/10.1029/2024jd042350).

Snow Avalanches

open access: yes, 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.

Using video detection of snow surface movements to estimate weak layer crack propagation speeds

open access: yesAnnals of Glaciology
Dry-snow slab avalanches release due to crack propagation in a weak snow layer under a cohesive snow slab. Crack propagation speeds can provide insights into the potential size of avalanches and inform fracture and avalanche release models. Despite their

Self-Organized Criticality on Quasiperiodic Graphs

open access: yes, 1999
Self-organized critical models are used to describe the 1/f-spectra of rather different physical situations like snow avalanches, noise of electric currents, luminosities of stars or topologies of landscapes.

Creep rupture as a non-homogeneous Poissonian process [PDF]

open access: yes, 2013
Creep rupture of heterogeneous materials occurring under constant sub-critical external loads is responsible for the collapse of engineering constructions and for natural catastrophes.

Quantifying the Rapid Propagation of Rainfall and Evapotranspiration Signals Into Soils

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Precipitation and evapotranspiration are major drivers of soil moisture dynamics, which in turn influence plant water availability, biogeochemical reactions, and trace gas emissions. However, it has been unclear whether evapotranspiration signals propagate through soil columns differently than precipitation signals do.

Snow metamorphism: a fractal approach

open access: yes, 2010
Snow is a porous disordered medium consisting of air and three water phases: ice, vapour and liquid. The ice phase consists of an assemblage of grains, ice matrix, initially arranged over a random load bearing skeleton.

Landsystems of the tropical high Peruvian Andes: Glaciers, lakes, wetlands and water resources in the Cordillera Vilcanota

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
We outline the geomorphological relationships between glaciers, lakes and bofedal wetlands, and the way in which moraines, talus slopes and sandar interact with catchment hydrology in the tropical Andes of Peru. Bofedales are well developed within glacial limits, with glacial processes such as erosion and formation of moraines providing the poorly ...

Calculation of Snow Avalanche Runout Distance [PDF]

open access: yesAnnals 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).
