Comprehensive landslide analysis using a tree-ring-based approach

Original language description

On the surface of complex landslide areas, other types of slope processes often occur in addition to the landslide movements themselves. However, in order to define the interrelationships or analyse their triggers, it is necessary to have chronological information on their past occurrence. In this study, a spectrum of tree-ring-based (dendrogeomorphic) approaches for spatio-temporal analysis of these processes is presented. The different approaches are applied to a selected complex landslide area with the presence of both creep and rockfall movements. Tree-ring-based data were obtained from standard increment cores as well as from tree roots exposed in tension cracks and from the modified surface of stumps. The presented approaches allowed not only chronological reconstruction of past activity processes but also reconstruction of their spatial activity and even estimation of the rate of displacements of selected landslide blocks. For each methodological approach, their advantages and limitations were evaluated. In addition, the obtained chronological data were used to evaluate potential triggers. The uniqueness of the tree-ring-based data was evident in detecting a wide variability in both the preparatory (up to 2-year periods with above-average rainfall in the case of landslides) and triggering factors themselves (3–5-day rainfall totals for landslides, extreme river discharges for activity tension cracks, or the influence of low temperatures during the winter season). Thus, this study provides a comprehensive overview of dendrogeomorphic approaches that can be used to obtain unique data on the spatio-temporal activity of processes in landslide areas in the past, estimating their rates and preparatory and triggering factors.
