In this data set, you will find: - an excel file where data are compiled to assess the risk in the Vögelsberg area (Watten Valley), in Austria; a shapefile composed of multiple layers to assess the social and ecological vulnerability toward the landslide hazard and the population exposure in the area; and a pdf to describe the dataset.
The Vögelsberg landslide is an active sub-system of a deep-seated gravitational slope deformation (DSGSD). Landslide movement in the area has likely been repeatedly active at least since the last glacial maximum (LGM) 22ka ago. Currently, a sub-system of the DSGSD in the lower part of the slope shows enhanced movement with annual displacements of up to 6 cm/a. (D2.1). Phases of acceleration correlate with moist periods of excessive, above-average rainfalls. In addition, enhanced infiltration of melt water during snow melt in spring may result in increasing movement rates. Secondary geomorphological processes come along with the slope movement.
Past major hazard events:
o In October 2008, the landslide’s footslope collapsed after prolonged, intense rainfalls, destroying arable land. Furthermore, the downslope moving material continuously narrows and lifts up the riverbed of the Watten stream below, bearing the potential of severe debris flows. (D2.1)
