Abstract

Despite its low to moderate seismic activity, most of Western Europe is characterized by a relatively high seismic risk due to the concentration of human and material properties presenting high-vulnerability. These regions have been affected by destructive earthquakes like the Ms=6 Lambesc earthquake, France, 11th June 1909, generating VIII-IX intensity values. Consequently, detecting tectonic structures that may lead to destructive earthquakes in such areas characterized by slow deformation rates, weak seismicity and dense vegetation coverage requires a multi-disciplinary approach which includes applied geophysics. The present geophysical study has been conducted in Provence (France), in the area touched by the 1909 Lambesc earthquake (Champion et al., 2000). The Provence domain is located at the transition between the Pyrenean and the Alpine mountain belts. It is bounded by the Nîmes fault to the west and by the external alpine thrusts to the east (Figure 1). Provence is affected by numerous east-west trending thrusts that have either northward (Sainte-Baume, Etoile, Ventoux-Lure) or southward (Alpilles, Lubéron, Costes-Trévaresse) vergences, and by regional NE-SW to NS trending strike-slip faults (Nîmes, Durance, Salon-Cavaillon faults).
