The study area is located in the western sector of Catanzaro Trough (central Calabria), extending from the Sila Massif, to the south, to Serre Massif to the north (Fig. 1). Although the partitioning in strike and oblique slip fault systems has been widely studied, it is still a matter of debate. These faults are considered responsible for the present-day shape of the whole Calabrian Arc, as well as the segmentation into several blocks that allow the opening of several transversal basins (Ghisetti and Vezzani, 1981; Turco et al. , 1990; Van Dijk et al., 2000; Peacock and Parfitt, 2002; Booth-Rea et al. , 2004; Tansi et al., 2007; Schlische and Withjack, 2009). According to Tansi et al. (2007) these structures are represented by three major faults;
