The occurrence of gravitative processes in high mountain areas are often supposed to be associated with permafrost degradation. The decrease in permafrost distribution in many mountainous areas could therefore be followed by an increase in gravitative processes. To gain a better understanding of the relationship of permaforst degradation and gravitative processes, monitoring of permafrost as well as monitoring of the processes are helpful. In our study, we use optical satellite (Pleiades tri-stereo) data in combination with airborne laserscanning data to map and monitor rock falls, landslides and debris flows in several study areas in Austria and northern Italy, where permafrost is evident. The mapped processes are then further investigated considering the influence of permafrost on the occurrence of the processes and their hazard potential.
