    Kurzfassung/Abstract

    Permafrost is being degraded worldwide due to the shift in external forcing caused by climate change. This has also been shown to affect the kinematics of active rock glaciers. We studied these changes on active rock glaciers with different characteristics in multiple epochs between 1922 and 2019 in Kauner- and Horlach Valley, Austria. A combination of historic maps, historical (aerial) photographs and airborne laser scanning data and their derivatives are used to analyse flow velocity, surface elevation and volume change. We identify possible links to external forcing parameters by analysing meteorological data (precipitation, temperature and snow cover) in and around the respective catchments. In general, the studied landforms show a significant acceleration of varying magnitude in the late 1990s and a volume loss to varying degrees throughout the investigation period. Besides, a distinct response of some rock glaciers to a warmer period in the 1940s - early 1950s can be observed. Despite the general trend, timing, magnitude and temporal peaks of rock glacier kinematics indicate a slightly different sensitivity, response or response time of individual rock glaciers to fluctuations and changes in external forcing parameters.
