Abstract

Vertical and horizontal borehole deformations have been measured in 3 rock glaciers in Switzerland. The results are compared in this paper. In addition, the results of 2 recent drilling campaigns, one on the Muragl and one on the Murtèl-Corvatsch rock glacier, are presented. Within degrading permafrost, the ice content decreases, the creep velocity increases and the shear zone rises towards the surface, where seasonal temperature changes and the presence of liquid water might also influence deformation
