Integration of Surface Wave Analysis with Electrical Resistivity and Seismic Refraction Tomography to Characterise Rock Glaciers

The study of glacier rocks is of utmost importance in recent years due to the known changes in the structure of this kind of environment. A correct understanding of this structure can avoid severe problems related to natural hazards. Therefore, we propose integrating the use of multichannel analysis of surface waves (MASW) with those already widely carried out (such as ERT and EST). Through this study, there is the chance of obtaining shear wave velocity (Vs) profiles and thus revealing possible velocity inversions caused by the presence of the frozen layer. In this study, a MASW has been carried out on data collected in the Swiss Alps over the past two years and the results show that the potential of this analysis for the characterization of mountain permafrost is promising.
