deformation composed of two main faults with relative slope changes at surface has been recognized on both walls of the quarry. Two sections ca. SW-NE oriented, were acquired (Fig. 3a). “Cava Civita West” section (Fig. 3b) shows a wide variability of resistivity values: from 70-80 Ohm·m in the southern part, to more than 4000 Ohm·m in the northern part. The resistivity values increase also downward with depth. The zone of high resistivity in the northern sector of the section is consistent with the presence of sub-outcropping rock that tends to deepen towards the south. The low resistivity values in the southern part of the section are consistent with the presence of fine grained deposits. In the central part, the resistivity values of ca. 500 Ohm·m are related to Fig. 2 – Geophysical and paleoseismological data acquired for the Castrovillari fault: a) 3D perspective from GOOGLE EARTH™ of the Cozzo S. Elia site: the Castrovillari fault scarp and the location of the ERT are reported; b) tomographic section of the Cozzo S. Elia site; c) location of the three tomographic lines acquired at the Castrovillari site; d) Castrovillari A and Castrovillari B tomographic lines; e) F1 N valley side with F1 fault highlighted and f) fault plane within the trench wall. 112 GNGTS 2013 S essione 1.1
