Monitoring Bonnard rock glacier under the effect of climate change

The purpose of this work is to consider the effects of climate change, specifically of global warming, on an alpine periglacial environment. The analysis is focused on the mechanical and morphological deformations of Bonnard rock glacier from the data obtained over 11 years, which are mainly from aerial photogrammetry and an in situ global positioning system. The acceleration of the surface material, namely rocks and boulders, becomes more evident during this time frame, going to increase lava streams and debris flows on Pétérey torrent and to endanger, in such a way, Zinal village, located at the foot of the slope.
