Description
The north Ligurian margin is a complex geological area on many accounts. It has witnessed several phases of highly contrasting deformation styles, at crustal scale and through shallow cover tectonics, simultaneously or in quick succession, and with significant spatial variability. This complex interplay in mirrired in intricate structures that make it hard to indentify active faults responsible for both the significant seismiciry observed and the tectonic inversion undergone by the margin, identified on morphostructural grounds. We present here the first preliminary results of the leg 1 of SEFASILS cruise conducted in 2018 offshore Monaco, in an effort to answer these questions by means of modern deep seismic acquisitions, using multichannel reflection and wide-angle sea bottom records. Some first interpretations are provided and point towards an active basement deformation that focuses at the limits between main crustal domains.
