Snow avalanches have a substantial impact upon human activity in mountainous regions. In this article I employ a climatological framework to examine the mechanisms by which snow avalanches occur. This is followed by a discussion of the hydrologic and geomorphic aspects of avalanches, and an examination of the current state of research as regards ...

This work is a critical update of the most recent and innovative developments of the avalanche science. It aims at re-founding it on clear scientific bases, from field observations and experiments up to strong mathematical and physical analysis and modeling. It points out snow peculiarities, regarding both static mechanical properties and flow dynamics,

Fracture mechanics of snow avalanches
Physical Review E, 2001Dense snow avalanches are analyzed by modeling the snow slab as an elastic and brittle plate, attached by static friction to the underlying ground. The grade of heterogeneity in the local fracture (slip) thresholds, and the ratio of the average substrate slip threshold to the average slab fracture threshold, are the decisive parameters for avalanche ...

Pressure of Snow Avalanches against Buildings
Applied Mechanics and Materials, 2011The paper aims to analyse the e ects of topography and building position on themagnitude of pressure exerted by snow avalanches against buildings, through a structural backanalysis and numerical uid-dynamics. Studying a real snow avalanche impact occurred in2008 which destroyed a village in Valsavarenche (Aosta Valley - IT), the attention is focused ...

Avalanche occurrence is closely related to the local meteorological conditions which may be quite variable in mountain topography. To investigate these conditions, and to provide information for avalanche forecasting, we designed and built a weather station which is currently relaying information to a base station from a remote site.

The sagas of mountaineering contain many accounts of sudden deaths from snow avalanches. For instance, the treacherous Nanga Parbat (9,000 m) in the Himalayas claimed 16 lives in 1937 when a German mountaineering team was trapped by an avalanche. Climbers of the Himalayas, Andes, Alaskan Ranges and even the Alps must always be on the look-out for ...

ABSTRACT After a general introduction to snow avalanches and their consequences, type classification is discussed, and classification schemes based on morphology, genesis and magnitude are described briefly. The first technical section deals with deformation and displacement of snow slopes prior to avalanche release, with the failure process, and ...
