🌋 Chaîne des Puys - Limagne fault tectonic arena
UNESCO-inscribed rift zone and volcanic landscape in central France
The Limagne Fault is a major crustal fracture in central France marking a rift zone where continental extension has shaped the landscape over millions of years. Together with the Chaîne des Puys volcanic field, it forms a UNESCO World Heritage Site recognized for its exceptional geological and educational value. The fault zone stretches approximately 32 kilometers and demonstrates the active processes of crustal thinning and magmatism that characterize the European Cenozoic Rift System.
