“…High-resolution ground-penetrating radar (GPR) surveying provides a means to image shallow complex structures not evident at the surface (e.g. Smith and Jol, 1995;Yetton and Nobes, 1998;Green et al, 2003;Liberty et al, 2003;Gross et al, 2004;Tronicke et al, 2006;McClymont et al, 2008aMcClymont et al, , 2008b.…”

“…In the last years, 2-D electrical tomography (ERT), electromagnetic (EM) and Ground Penetrating Radar (G.P.R.) were widely used in active fault surveys (Cai et al, 1996;Suzuki et al, 2000;Demanet et al, 2001;Green et al, 2003;Slater and Niemi, 2003), mainly for two reasons. First, these techniques are highly sensitive to electrical properties, particularly resistivity, which show significant variations in shallow Quaternary layers.…”

“…Near-surface geophysical prospecting has now become a major tool, particularly in active tectonics, for constraining the geometry of faults affecting the shallow layers (among others, Demanet et al 2001;Green et al 2003;Carvalho et al 2006). The choice of the investigating technique mainly depends on the expected geophysical contrast, the target depth and the required resolution.…”

International audienceIn the Belledonne massif, the steep Paleozoic Belledonne Middle Fault (BMF) separates micaschists, displaying numerous landslides, from amphibolites. The massif is incised by the lower Romanche river valley. When crossing the BMF, the valley widens into a lozenge-shaped basin recently interpreted as an active pull-apart type structure associated with a major N110 striking Quaternary fault. Multidisciplinary investigations were carried out in the basin to check if this model has implications on the seismic and landslide hazard assessment. This study demonstrated the existence of a N80 sinistral strike slip Séchilienne Fault Zone (SFZ). This fault zone is suspected to offset the BMF by 375 m across the basin. Geophysical experiments revealed that the bedrock depth increases strongly in the basin, up to 350 m. Our study invalidates the active pull-apart origin of the basin and suggests it results from Quaternary glacial and fluvial erosion processes, magnified by the intersection of two inherited structures, the BMF and the SFZ
