| Anotation | The recent activity of ancient landslides is often unknown or supposed as low to none. The lack of data about their activity can even lead to fatal underestimation of landslide hazard because small-magnitude movements often precede their catastrophic reactivation. The long-term monitoring of landslide movements is usually necessary for determination of recent activity of ancient landslides. This project solves the possibility of recent activity estimation without monitoring. The combination of tree-ring based (dendrogeomorphic) methods with the data from several monitored landslides (reference) will create the calibrated approach for application on unmonitored landslides with unknown activity. Moreover, the developed approach will benefit from data about depth and inner structure of landslides from geophysical measurements (three most common methods: ERT, GPR, SSR). Deep-seated gravitational landslides will be the only type of studied landslides. The developed approach will be applied on unmonitored landslides to test the possibility of regional estimation of landslide hazard. |
