138 GNGTS 2017 S essione 1.2 Similar inferences can be formulated for the CGDF, based on stratigraphic data (Lanzafame and Zuffa, 1976, Spina et al., 2011) and on the geometry of the syn-extension sedimentary prism, detectable from seismic interpretation (Fig. 3b). Finally, the hypothesized association with instrumental seismicity and their possible role as lower boundary of high-angle seismogenic fault, are elements supporting the present activity of both the investigated structures.
