Abstract

In the European Alps, the occurrence of large rock slope failures has been largely influenced by the Quaternary glacial history. In the Southern Swiss Alps in the territory between Canton Ticino and Canton Grisons, several deposits of large rock slope collapses can be observed. To characterize the connection between glacial retreat and slope collapse, a detailed geochronological assessment of both phenomena is essential. This research aims to define the exposure age of the mapped rockslide/rock avalanche deposits through Schmidt hammer exposure-age dating (SHD) and analyze the achievements in relation to the collapse volume to obtain a morphodynamic interpretation during deglaciation.
