The Messina Strait and surrounding areas are one of the most interesting regions western Mediterranean Sea, characterized by complex interplay between Mesozoic-Paleogene Ionian basin, where Calabrian Arc accretionary prism extends towards southeast, Neogene Tyrrhenian back-arc basin to northwest.Complex fault networks with different kinematics, running from inner side arc through coast Sicily, as far Hyblean Plateau, result coexistence geodynamic settings in area. Some these faults responsible for several largest earthquakes occurred southern Italy Sea recent times. Different works aimed at establishing a relationship seismogenic sources mapped faults, defining location rupture mechanism some lineaments. Even tough, many uncertainties still exist offshore areas, kinematics geometry cases poorly constrained.In this work, we focus on group located northern sector Gioia Basin (southern Sea). We aim understanding style deformation area, investigate role played main framework regional setting Ionian-Tyrrhenian transition zone. This study is based interpretation multichannel seismic dataset (TIR10 survey), combined analysis morpho-bathymetric geodetic data, numerical modeling. multidisciplinary multiscale approach can contribute unravel particular region context stepwise migrating subduction system provides new constrains highly populated area severe tsunamigenic hazard.
