The Chauvet Cave (Ardèche), discovered in 1994, is characterised by its cave art, which is among the oldest images of mankind, by its numerous palaeontological remains and by its remarkable state of preservation. It has been condemned to the public since its discovery for preservation. However, this stable state of preservation is linked to the climatological regulation of the scree that closes the entrance to the prehistoric porch. It seems to be settling down and another stage of the cliff's collapse remains to be assessed with the analysis of the stability of the Pillar of Abraham.The epicenter of the Le Teil earthquake 2019 is located at the northeastern part of the Cévennes fault system and the Chauvet cave sits in the immediate vicinity of the southwestern part of this active fault system. Within the framework of the programme funded by AURA PAI, the main aim is to monitor and define the vulnerabilities of the entrance area to the Chauvet cave and more specifically to analyse the response of the pilar evolution to climatic and seismic triggers.
