Geological setting of the Vaňov landslide area
Abstract
The Čertovka landslide initiated in autumn of 1994 and it is still active. The landslide started as a rock-fall of basaltic blocks and continues as a mass-flow or debris flow. The head scarp of the landslide exposes volcanic deposits of Late Eocene to Early Oligocene Ústí Formation. The main part of the volcanic sequence comprises subaquatic lavas and associated hyaloclastites, interbedded with subaquatic pyroclastic deposits. In the upper part of the sequence, subaerial scoriaceous deposits were documented. The succession documents transition of subaquatic volcanic activity into subaerial, probably due to levelling of the water reservoir.
