dc.description.abstractTo 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 optimally prepared for the comparison with the help of specific software. The results of the drone surveys and the terrestrial measurements showed the same patterns observed with previous investigations. In the central part of the rock glacier and on the northern outburst floodplain the velocities were higher than on the rest of the rock glacier tongue. Locally, creep velocities of up to 13.61m in seven years were calculated and the mass movements in the model of the flow behavior displayed local volume changes and displacements up to 4m. The velocities of the individual years showed correlations with the average temperature measured in Switzerland. The change of the creep velocity during the mild and snow-poor winter of 2019/2020 was particularly recognizable. Furthermore, the creep velocities at Muragl rock glacier are relatively high in comparison to the neighboring Murtel-Corvatsch rock glacier with velocities of up to 2m/a. These results highlight that the biggest mass movement were situated in the north central Part of the rock glacier and on the northern outburst, which corelates with previous studies. Additionally, correlations between rising average temperatures in Switzerland and the creep velocity at the Muragl rock glacier were clearly recognizable. Based on the results of this study and the literature researched, possible future trends for the Muragl rock glacier were made.de_CH
