From: Rock glaciers throughout the French Alps accelerated and destabilised since 1990 as air temperatures increased

Fig. 5: Evolution of the displacement rates of destabilised rock glaciers.

On panel a are presented the displacement rates of destabilized rock glaciers grouped by geographical regions. The dots on the displacement rate graphs indicate the observed onset of the destabilised phase. The rock glaciers presented are designated by an acronym; CL: Col du Lou, PB: Pierre Brune, RN: Roc Noir, PM: Pierre Minieu, PP: Pointe Paumont, TL: Tête de Longet, GB: Grand Bérard, PC: Pointe du Clot, OF: Ouille du Favre, PA: Pointe des Arses, AS: Aiguille Scolette, PR1: Petite Rochebrune 1, PR2: Petite Rochebrune 2, PR3: Petite Rochebrune 3, RD: Rocher des Dents, CA: Pic Caramantran, CC1: Crête du Coq 1, CC2: Crête du Coq 2. On panel b is presented the mean annual air temperature anomaly in the period 1850–2018 for the whole French Alps.
