Accessible year round by cable car, the AdMcomprises two main peaks: (i) the Piton Nord with the cable car arrival station, where 4 crack-meters are placed onfour major fractures, and (ii) the Piton Central with many touristic infrastructure, equipped with three 10-m-deepboreholes with 15 temperatures sensors since 2009, and where 2 crack-meters are installed along a major fracture.Three major kinematic regimes are observed: (i) opening of clefts when the rock temperature becomes positive,followed by closing during the cold period, (ii) summer opening continued by a winter opening, and (iii) closingduring the warm period followed by opening in winter. %G English %L hal-01781303 %U https://sde.hal.science/hal-01781303 %~ SDE %~ UNIV-SAVOIE %~ UGA %~ CNRS %~ OSUG %~ EDYTEM %~ GIP-BE %~ EDYTEM-THEME-CHANGEMENTS-ENVIRONNEMENTAUX-SOCIETES %~ USMB-COMUE
