GNGTS 2017 S essione 1.2 151 conclusion, we provide a first application of attribute analysis on seismic sections across the central Apennines. Our results provide new subsurface images of the epicentral area. The study confirms that the attribute analysis represents, even on vintage seismic section of variable quality, an efficient aid for the interpreters to shed light on the deep structures of regional and seismogenic importance. Acknowledgments We are grateful to Eni S.p.A for providing unpublished seismic sections for this project, after the recent seismic crisis of the Central Italy.

This transfer zone is composed of two major faults (Capo Granitola and Sciacca Fault) which display mainly a transcurrent tectonic regime (Fig.1). This regional
