Fracture kinematics in steep bedrock permafrost, Aiguille du Midi (3842 m a.s.l., Chamonix Mont-Blanc, France)

Résumé

Permafrost-affected rockwalls can suffer from mechanical fatigue related to thermo-cryogenic processes. However, these processes, the rock slope kinematics, and the links between both remain largely unclear. This study reports five years of crackmeter measurements at 2-hours resolution from six of the main perennially ice-filled rock clefts at the Aiguille du Midi (3842 m a.s.l., Mont Blanc massif). Seasonal and inter-annual variations as well as response of fracture kinematics to thermo-cryogenic process are analyzed.
