Sgroi 1 1 Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Etneo, Catania, Italy 2 Istituto di Scienze Marine - Consiglio Nazionale delle Ricerche, Bologna, Italy The current tectonic setting of the southern Tyrrhenian plate boundary is related to the poly-phased episodes of oceanic subduction, slab retreat, and continental collision occurred since Neogene in response to the Eurasia-Nubia convergence ( e.g. Faccenna et al. , 2001 and references therein). Geodetic data highlight the presence of distinct deformation belts separating the Tyrrhenian Sea, and the Sicily and Calabria blocks, which interfere in NE Sicily (Palano et al. , 2012). A recent (Middle Pleistocene) re-organization of the Africa/Eurasia plate boundary was postulated based to the analyses of marine geophysical data in the Ionian Sea (Polonia et al. , 2016) where two sets of oppositely dipping fault systems, the Ionian Fault (IF) and Alfeo- Etna Fault (AEF) systems, impinges along the coast of NE Sicily (Polonia et al. , 2017). Such lithospheric faults accommodate slab tearing processes and connect the deformation zone along the northern margin of Sicily with the Calabria subduction along dextral shear corridors including the Etna volcano and the Messina Straits region. In such a tectonic maze, the so called “Aeolian-Tindari-Letojanni” Fault System (ATLFS), a complex lithospheric discontinuity consisting of a broad NNW-SSE- to NW-SE-trending deformation zone from the Aeolian Islands down to the Ionian coast of Sicily, has been interpreted as the current shallow expression of a sub-vertical lithospheric-scale tear-fault, bordering the southern edge of the Tyrrhenian subduction zone at depth (Palano et al. , 2017 and references therein). A number of geological and geophysical evidence allowed to define main tectonic features on the southern Tyrrhenian offshore (Gulf of Patti) and coastal areas ( i.e. across the Peloritani
