Fig. 1: Structural and seismotectonic setting of the 11 November 2019 Le Teil earthquake.
From: Surface rupture and shallow fault reactivation during the 2019 Mw 4.9 Le Teil earthquake, France
a Seismotectonic map of the Rhône River Valley where occurred the 11 November 2019 Mw 4.9 Le Teil earthquake (44.518°N and 4.671°E). The black and white sphere indicates the reverse-faulting focal mechanism; red and purple circles are instrumental and historical seismicity, respectively; the green ellipse corresponds to the Tricastin swarm; black lines are faults from the Aubenas geological map4 with the La Rouvière Fault (LRF) in red. CF Cévennes Fault, MF Marsanne Fault. The shaded DTM is from BD ALTI 25 m (IGN); MC and Al in the inset are Massif Central and Alps, respectively. b Simplified geological map of the western boundary of the Southeastern Basin (modified from refs. 7,44). A: Plio-Quaternary volcanism; B: Miocene–Pliocene sediments; C: Oligocene sediments; D: Mesozoic sediments; E: Paleozoic crystalline basement (Massif Central); F: major faults (NE termination of the Cevennes fault system (CFS) in red, CF and MF for Cévennes Fault and Marsanne Fault, respectively). Black dots indicate main population centers.
