Calibration and application of the MN2D dynamics model to the avalanches of Las Leñas (Argentina) [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2002
During the winters of 1999 and 2000 large avalanches occurred in the ski resort of Las Leñas (Los Andes, Mendoza, Argentina). On 8 September 1999 an avalanche of new, dry snow ran over a path with a 1000 m vertical drop. On 30 June and on 1 July 2000

Seismically Induced Snow Avalanches: The Central Italy Case

open access: yesFrontiers in Earth Science, 2020
Snow avalanches are critical events due to the sudden instability of snow in mountain regions. Seismically induced snow avalanches, due to a particular type of trigger perturbing snow-covered slopes, are occasional events in geodynamically active ...

Modelling the system behaviour of wet snow avalanches using an expert system approach for risk management on high alpine traffic roads [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2005
The presented approach describes a model for a rule-based expert system calculating the temporal variability of the release of wet snow avalanches, using the assumption of avalanche triggering without the loading of new snow.

Cellular-Automata Model for Dense-Snow Avalanches [PDF]

open access: yesJournal of Cold Regions Engineering - ASCE, 2007
This paper introduces a three-dimensional model for simulating dense-snow avalanches, based on the numerical method of cellular automata. This method allows one to study the complex behavior of the avalanche by dividing it into small elements, whose ...

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 ...

The Intermittency Regions of Powder Snow Avalanches [PDF]

open access: yesJournal of Geophysical Research F: Earth Surface, 2018
Powder snow avalanches are typically composed of several regions characterized by different flow regimes. These include a turbulent suspension cloud of fine particles, a dense basal flow, and an intermittency frontal region, which is characterized by large fluctuations in impact pressure, air pressure, velocity, and density, but whose origin remains ...

What weather variables are important for wet and slab avalanches under a changing climate in a low-altitude mountain range in Czechia? [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2022
Climate change impact on avalanches is ambiguous. Fewer, wetter, and smaller avalanches are expected in areas where snow cover is declining, while in higher-altitude areas where snowfall prevails, snow avalanches are frequently and spontaneously ...

Linking snow depth to avalanche release area size: measurements from the Vallée de la Sionne field site [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2016
One of the major challenges in avalanche hazard assessment is the correct estimation of avalanche release area size, which is of crucial importance to evaluate the potential danger that avalanches pose to roads, railways or infrastructure.

Snow Avalanche Frequency Estimation (SAFE): 32 years of monitoring remote avalanche depositional zones in high mountains of Afghanistan [PDF]

open access: yesThe Cryosphere, 2022
Snow avalanches are the predominant hazards in winter in high-elevation mountains. They cause damage to both humans and assets but cannot be accurately predicted. Here we show how remote sensing can accurately inventory large avalanche depositional zones

Risk assessment in the North Caucasus ski resorts [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2016
Avalanches pose a significant problem in most mountain regions of Russia. The constant growth of economic activity, and therefore the increased avalanche hazard, in the North Caucasus region lead to demand for the development of large-scale avalanche ...
