Evidences of active tectonics are widely present in the Sicylian mountain belt as suggested by the presence of Holocene faulted deposits and by diffused seismicity.Particularly, the southern edge of the Tyrrhenian Basin, and surrounded areas, are characterized by a very complicate geodynamicsetting.Northern Sicily is affected by Plio-Pleistocene destral strike slip faults with associated antithetic left strike slip and coeval E-W normal faults.Geological and structural analyses, carried out in central-northern Sicily, allowed to identify a further prevailing N-S normal faultssystem (Middle Tyrrhenian System) that shows evidences of neo-tectonic reactivation in very recent age.In Gangi area some of these faults cut Roman votive niches,clearly becoming a chronological marker and allowing the deformationdating.The modest extension and offset with limited frequency in outcrop of such structures carry to think the system to the incipient stage.Trend and age of structures recognized indicate these like thepossible on-shore expression of the more recent Tyrrhenian spreading connected to the opening of the Marsili basin.
