Geomorphological and Morphometric Analyses of the Catanzaro Trough (Central Calabrian Arc, Southern Italy): Seismotectonic Implications

In this work, we investigated the landscape response to recent activity of faults affecting Catanzaro Trough, a seismically active structural basin that developed transversally Calabrian Arc (Southern Italy) during Neogene–Quaternary. We carried out geomorphological and morphometric study drainage networks basins intercepted by Quaternary were previously mapped through remote field analyses. The confirms occurrence north Trough WNW–ESE-oriented left-lateral strike-slip fault system (here named South Sila Piccola Fault System), which accommodates differential SE-ward migration upper crustal sectors Arc, south-dipping oblique (the Lamezia-Catanzaro characterized predominant normal component movement. latter delimits transition from regime an extensional in south. Inside detected for first time NNE–SSW-trending, WNW-dipping Caraffa System). This contributes accommodate extension occurs orthogonally southern sector Arc. analysis revealed these systems. particular, System is evidenced uplift tilting discrete areas inside basin. Given its location, geometry, kinematics, could be responsible large historical earthquakes.
