Paleoseismological investigations of the La Rouvière fault, unexpected source of the 11-11-2019, Mw 4.9 Le Teil surface rupturing earthquake (Cévennes fault system, France)

A 2019 earthquake (Mw 4.9) in the Cévennes region of France revealed unexpected surface ruptures linked to the La Rouvière fault, part of the broader Cévennes fault system. Paleoseismological investigations, documented during the 2022 INQUA PATA Days, identified previously unrecognized fault activity in this Mediterranean agro-pastoral landscape. The study highlights the significance of such faults as seismic hazards in regions with low to moderate earthquake risk. By analyzing surface ruptures and geological evidence, researchers provided critical insights into the fault's behavior, contributing to better understanding of seismic risks in UNESCO World Heritage Sites.
