“…In the Southern Apennines, the chain is affected more by northwest-southeast transtensional/transpressional faults than by almost pure northeast-verging thrusts as it was during the previous events (Gasparini et al, 1982;Patacca and Scandone, 1987). The whole sector becomes then a sort of lateral ramp for the pure thrust deformations occurring presently off the Ionian side of the Calabrian Arc (Rossi and Sartori, 1981) at the hinge zone of the southern arcuate orogen (Fig.…”

“…The Pleistocene stress pattern implies transform lineaments more or less parallel to the present strike of Southern Apennines and normal to the Calabria-Peloritan arc (Gasparini et al, 1982). Tyrrhenian Sea (see Sartori, et al, 1987b, and references therein).…”

“…Furthermore, they form rather a ring-shaped structure considering also the submarine seamounts at the southern margin of the Marsili basin, which is characterised by oceanic crust. The active volcanoes are located along strike-slip tectonic lines (Gasparini et al 1982;Beccaluva et al 1982). Thus, an alternative hypothesis for the Aeolian volcanism is a relationship with a back-arc environment, where magma generation is attributed to asthenospheric domal uplift developing along a NW-SE trending extensional tectonic zone Mazzuoli et al 1995).…”

“…Focal plane solutions proposed by authors in the last decades show controversial interpretations of the possible geometric and kinematic pattern of the 1968 seismogenic source. Computed focal solutions provide possible faulting mechanisms that range from thrusting on a WSW-ENE striking plane to right lateral transpression on a NNW-SSE striking plane (Mckenzie, 1972;Bottari, 1973;Gasparini et al, 1982;Anderson and Jackson, 1987;Frepoli and Amato, 2000). This ambiguity remains still unresolved due to the fact that the source of the 1968 earthquake sequence did not produce a typical seismic landscape (sensu Michetti, 2005) and that, as a result of low magnitude of the events, coseismic fault ruptures have never been observed until now.…”

a b s t r a c tIntegrated geological, geodetic and marine geophysical data provide evidence of active deformation in south-western Sicily, in an area spatially coincident with the macroseismic zone of the destructive 1968 Belice earthquake sequence. Even though the sequence represents the strongest seismic event recorded in Western Sicily in historical times, focal solutions provided by different authors are inconclusive on possible faulting mechanism, which ranges from thrusting to transpression, and the seismogenic source is still undefined. Interferometric (DInSAR) observations reveal a differential ground motion on a SW-NE alignment between Campobello di Mazara and Castelvetrano (CCA), located just west of the maximum macroseismic sector. In addition, new GPS campaign-mode data acquired across the CCA alignment documents NW-SE contractional strain accumulation. Morphostructural analysis allowed to associate the alignment detected through geodetic measurements with a topographic offset of Pleistocene marine sediments. The on-land data were complemented by new high-resolution marine geophysical surveys, which indicate recent contraction on the offshore extension of the CCA alignment. The discovery of archaeological remains displaced by a thrust fault associated with the alignment provided the first likely surface evidence of coseismic and/or aseismic deformation related to a seismogenic source in the area. Results of the integrated study supports the contention that oblique thrusting and folding in response to NW-SE oriented contraction is still active. Although we are not able to associate the CCA alignment to the 1968 seismic sequence or to the historical earthquakes that destroyed the ancient Greek city of Selinunte, located on the nearby coastline, our result must be incorporated in the seismic hazard evaluation of this densely populated area of Sicily.
