Alpine mountains are affected by significant geomorphological processes whose evolution is partly conditioned by permafrost warming: rockfalls of various volumes, destabilisation of rock glaciers, and cryokarst. These phenomena, because of their inte

Rock glaciers—ice-rich creeping landforms typical of permafrost mountain ranges—can develop an anomalous landslide-like behaviour called destabilisation. This behaviour is characterised by failure mechanisms (including cracks and crevasses) and i

International audience; As evidenced by existing inventories, the semi-arid Andes (Chile and Argentina) has a high density of active rockglaciers and host some of the largest ones in the world. The movement of rock glaciers, which is crucial forunder

International audience; Recent observations and geodetic measurements in the European Alps show thatchanges are occurring on rock glacier dynamics, ranging from moderate velocityvariations to strong acceleration or even total collapse. These changes
