“…High-magnitude avalanche years were significantly correlated with positive snowpack anomalies in the USA (Reardon et al 2008) and total snowfall in Canada (Dubé et al 2004). Similarly, Casteller et al (2011) found a significant correlation between years with large avalanche activity and abundant precipitation during austral winters (May to October) in Argentina.…”

Tree ring eccentricity was used to reconstruct landslide activity in the last 138 years in the Urbas landslide located at Potoška planina in the NW part of the Karavanke Mountains, Slovenia. The research was based on the dendrochronological sampling of Norway spruce (Picea abies (L.) Karst.) in areas of varying landslide intensity. Analysis of a sudden change in the eccentricity index of 82 curved trees concluded that there were 139 growth disturbances and 16 landslide reactivations between 1880 and 2015, with a landslide return period of 8.5 years. Using lidar data, changes in the surface of the digital terrain model (DTM) were compared with changes in the eccentricity index of trees at the same location in the period 2014–2017. On the basis of temporal changes in the eccentricity index and by using spatial interpolation, landslide activity was reconstructed for the period 1943–2015. During this period, landslide intensity increased in the central part of the landslide. Although categorization into seven categories of different stem curvature was proposed, no distinction between categories with respect to their eccentricity index was found.

“…However, since the turn of the millennium, attention has also been aimed at other mountains, e.g., the Alps (Casteller et al, 2007;Corona et al, 2010), the Pyrenees (Muntán et al, 2009) and the Andes (Mundo et al, 2007;Casteller et al, 2011).…”

“…Very detailed methodological research on the problem of setting the appropriate level of this index performed by Corona et al (2012) pointed to the need to increase the threshold with decreasing sample size; otherwise, many past avalanches can be omitted and potential noise (identification of "false" events) can occur. The other statistical analysis approach is based on a special "scoring" scheme, which assigns points to years according to the number and severity of indicators of the avalanche and the total amount of disturbed trees (Casteller et al, 2011). The dating of avalanches can broadly use loads of dead wood (i.e., the broken trunks of trees growing in the path before the fall) to estimate the ages of their breakage by means of cross-dating.…”

Absolute dating of mass movements is crucial for disentangling possible release factors and determining the frequency of events. Here, we present an overview of a recent approach to dendrochronological dating of rockfalls, flows, landslides and avalanches. The results, based on 69 casestudies, show that methodological approaches to sampling and material processing differ considerably for different types of mass movements. Landslides are usually detected through abrupt growth changes and changes in stem eccentricity, whereas high-energy events as avalanches and flows are mostly identified by the formation of traumatic resin ducts, reaction wood, growth injuries and eccentricity changes. Cross-dating of dead wood is applicable as well. The dating of most mass movements except landslides is common, even with sub-annual resolution. In comparison to other methods of absolute dating, the main benefit of dendrochronology still lies in the high temporal resolution of the results. If living material is accessible, on-going research progress makes absolute dating of most mass-wasting events possible with sub-annual precision.
