“…Eckert et al, 2009) assessment on the path scale. However, the EPA is also well suited for large-scale studies on relations with snow and meteorological covariates (Jomelli et al, 2007), major avalanche episodes (Eckert et al, 2010c) and spatial variations in avalanche activity (Eckert et al, 2007b). For climate studies, the major advantages of the EPA are the long time span of the available data series in the context of a well-structured observation network, giving a relatively accurate view of the spatio-temporal fluctuations of natural avalanche activity in France over the last century.…”

“…In this case, the snow mantle depth decreases slowly under a quasi-deterministic dynamics during no-snow days and increases suddenly during snow events until an avalanche resets the process. The return-time statistics of avalanche occurrence and size are known to differ from those of preceding precipitation (Ancey et al 2003;Eckert et al 2007). In particular, the slope of the hillside determines the equilibrium between the weight of the snow mass and the friction forces, while snowfall events are responsible for the increased local load.…”

“…This is an area of intense research in the geophysical sciences (Harbitz et al 2001;Ancey et al 2003;Schweizer et al 2009), which has traditionally focused on physically based models. Because of the inherent stochasticity driving the avalanche formation and triggering (Eckert et al 2007;Cappabianca et al 2008), such efforts have only been partially successful. In particular, some important yet unexplored questions regard: (i) the probability distribution of avalanche size occurrence in relation to terrain slope and snow compaction processes, (ii) the dependence of the return time of avalanche on the return time of preceding snowfall, and (iii) the identification of those slopes on which prediction of avalanche detachment and size is most uncertain.…”
