Chauvet volcanic eruption images

Very interesting! Many years ago, while visiting the Bara-Bauh cave, I've been told that there was evidence of rocks'collapse probably connected with the Mont Dore volcanic chain: could it be the same origin?
Thanks,

Hi Giorgio

We recently re-dated the Mont-Dore large flank collapses you mentionend and they are much older. The biggest ones are found in the Perrier plateau and are between 2,6 and 2,5 Ma (Nomade et al., 2015 JVGR). However, some younger minor events occured about 700 and 300 ka but are still too old to be related to the Spray-shape signs in the Chauvet Pont d'Arc.
The southern edge of the Bas-Vivarais volcanic field is something disconnected from the Mont-Dore Massif activity (stratovolcano). It is made of 17 monogenic cones that erupted between 40 and 20 ka.
