Shallow landslide inventory

As a first step of any study on landslide susceptibility, hazard or risk a landslide inventory is compiled. In the project C3S-ISLS an inventory focussing on shallow landslides was prepared for the study areas Laternser valley, Kleinwalser valley and the communities Au and Schnepfau in Vorarlberg (Austria). In total more than 2300 shallow landslides have been mapped based on nine sets of high-resolution orthophoto series aided by derivatives of two airborne laser scanning campaigns. The figure below shows an overview of the landslides mapped in the study areas on top of the tectonical map (available on onegeology.org). Especially in the Kleinwalser valley the high susceptibility of the Flysch formation is apparent.
