Seismic Exploration of the Deep Structure and Seismogenic Faults in the Ligurian Sea by Joint Multi Channel and Ocean Bottom Seismic Acquisitions: Preliminary Results of the SEFASILS Cruise

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