Brief synthesisThe Chaîne des Puys - Limagne fault tectonic arena, situated in the Auvergne-Rhône-Alpes Region in the centre of France, is an emblematic segment of the West European Rift, created in the aftermath of the formation of the Alps 35 million years ago. The Chaîne des Puys - Limagne fault tectonic arena presents a coincident view of all the representative processes of continental break-up and reveals their intrinsic links. Overall, human impact remains limited and does not compromises the geological value of the Chaîne des Puys - Limagne fault tectonic arena concerning the integrity of the property in relation to criterion (viii). The main potential threats are thus the quarries, urbanisation, encroachment of forest masking the geological features, and erosion of soils linked to human action. Care is needed to manage the balance between forest cover and pasture when seeking to optimize the exposure of the property’s geological features.
