| Summary: | To determine the influence of climate warming on permafrost, creep velocities of rock glaciers are a reliable measure. As rock glaciers increase creep velocities with rising permafrost temperatures, the kinematics indirectly reflect the thermal conditions of a rock glacier. In this study, the kinematic and morphological characteristics of Muragl rock glacier were investigated using drone images from 2015 and 2022, and correlations to changing ground surface and air temperatures over the same period were examined. Data collection was performed using drone images and terrestrial surveying. The collected data sets from the different methods were compared and tested for similar patterns in the rock glacier kinematics. The suitability of the applied methods for such kind of investigations was determined by comparing the different results and recognizable patterns as well as their plausibility in comparison with other investigations at Muragl rock glacier. The collected data sets were evaluated, visualized and ... |
