The effectiveness of dendrogeomorphic methods for reconstruction of past spatio-temporal landslide behaviour

Šilhán, Karel The effectiveness of dendrogeomorphic methods for reconstruction of past spatio-temporal landslide behaviour / Karel Šilhán ...

However, their real accuracies have not yet been deeply evaluated. The purpose of this study is to evaluate the effectiveness and accuracy of tree ring based methods by comparing them with field monitoring data on landslide behaviours. A total of 876 increment cores have been extracted from 219 P. sylvestris individuals to reconstruct the past spatio-temporal activity of the Ľubietová landslide (1977). The landslide re-activation events recorded within the tree ring series of each tree have been spatially interpolated. Those data have been compared with the long-term field monitoring based on the measured changes in the stabilized geodetic point positions. In general, the tree ring based spatio-temporal landslide evolution revealed a higher landslide activity than the monitoring-based one (particularly in the lower part of the landslide).
