Geophysical investigation of a recent shallow fault

The surveyed area is located in the central part of the upper Rhinegraben, a few kilometres south of Wissembourg, close to the western border. A normal fault has been evidenced in the open sand quarry of Riedseltz. It was an opportunity for 1) practising geophysical prospecting, as part of the final year curriculum of Ecole de Physique du Globe, 2) testing various methods for imaging a shallow fault, 3) locate and follow the fault outside of the quarry. The study was partly supported by the BRGM.
