Description :
A method based on dendrochronology was developed to analyse the spatial and temporal variability of landslide activity. The method involves a feature of wood anatomy, tree-ring eccentricity, which is used in the dating procedure. The degree of eccentricity is used as an indicator of the intensity of the mechanical stress affecting a tree stem in a certain year. The aim was to develop a mathematical indicator of tree-ring eccentricity for dating the recent dynamics of landslides. A method presented in this paper is also designed for practical application in detecting initial landslide activity and allowing the determination of triggering factors. The method was used in the Carpathian and Sudeten Mountains on three landslides with different sizes and geological settings.
