“…The stratigraphy and structural architecture of the wedge-top basins of Ionian Calabria and the timing of deformation have been influenced by compressive structures leading to the development of distinct and asymmetric depocentres. Such on-land structures are similar to doubly verging thrusts (Critelli et al, 2011;Doglioni, Merlini, & Cantarella, 1999;Muto, Spina, Tripodi, Critelli, & Roda, 2014;Roveri, Bernasconi, Rossi, & Visentin, 1992;Van Dijk et al, 2000) documented in the Ionian offshore and associated with the activity of NW-SE striking shear zones (Brutto et al, 2016;Knott & Turco, 1991;Muto et al, 2015;Van Dijk et al, 2000). In the study area, the strain partitioning along left-lateral strike-slip faults led to the development of transpressional features, such as the Cariati Nappe (CN).…”

Along the northern Ionian margin of Calabria, three Neogene basins comprise wedge-top depozones containing syntectonic deposits which cover the frontal part of the fold-thrust belt. One of the best exposed onshore allochthonous siliciclastic successions is represented by the Cariati Nappe, cropping out in the Cirò Basin. Field geological mapping and aerial interpretations were used to characterize the stratigraphy and tectonics of the area between the Arso Stream and Nicà River catchments (about 170 km 2 ), including a Paleozoic metamorphic basement complex unconformably overlain by Upper Oligocene to Quaternary siliciclastic deposits and minor carbonates. This paper presents a 1:25,000 scale map of the Ionian study area, providing lithological and structural data towards reconstructing its tectono-sedimentary evolution. ARTICLE HISTORY

“…Finally, the modern subducting slab is bounded by two main tear faults (Subduction Transform-Edge Propagators, STEP) (Fig. 1a): (1) the Tindari-Letojanni fault to the south 41 ; and (2) a main northern fault not uniquely defined, i.e., the Sangineto Line 41 with its offshore prolongation beneath the Palinuro volcanic complex 42 ; or the more southern Catanzaro shear zone 43 .…”

“…Extensional and strike-slip faults fragment longitudinally (from N-S to SW-NE) and transversally (from E-W to ESE-WNW) the Calabrian block 44,45 . The N-S to SW-NE-trending normal faults accommodate the rapid uplift of the Calabrian belt since middle Pleistocene time 43,45,46 , in particular along the western side of the belt (western Calabria), where widespread subsidence is observed 47 . Normal faults extend also offshore forming partially submerged graben or half-graben systems, such as the Lamezia graben 43,48 .…”

Understanding magmatic systems and deep hydrothermal circulation beneath arc-volcanoes provides insights into deep processes associated with slab-subduction and mantle-wedge partial melting. Here we analyze hydrothermal flow below a structural high (Capo Vaticano Ridge, CVR) located offshore Capo Vaticano (western Calabria) and affected by magmatic intrusions generated from above the Ionian subducting-slab. In order to explain observations, we combine geophysical and numerical modelling results. Fluid-flow modelling shows that temperature distribution and geothermal gradient are controlled mainly by hydrothermal circulation, in turn affected by heat source, fault pattern, rock permeability, basement topography and sediment thickness. Two main faults, shaping the structural high and fracturing intensely the continental crust, enable deep hydrothermal circulation and shallow fluid discharge. Distribution of seismicity at depth supports the hypothesis of a slab below Capo Vaticano, deep enough to enable mantle-wedge partial melting above the subduction zone. Melt migration at shallow levels forms the magmatic intrusions inferred by magnetic anomalies and by δ3He enrichment in the discharged fluids at the CVR summit. Our results add new insights on the southern Tyrrhenian Sea arc-related magmatism and on the Calabrian inner-arc tectonic setting dissected by seismogenic faults able to trigger high-destructive earthquakes.

“…From a tectonic perspective, during the late Neogene and Quaternary, the fold-and-thrust belt of northern Calabria experienced multiphase tectonic deformation and alternating transpressional and transtentional tectonic events (Borrelli, Critelli, Gulla, & Muto, 2015;Brutto et al, 2016;Longhitano, Chiarella, & Muto, 2014;Muto et al, 2015;Scarciglia et al, 2016;Spina, Tondi, & Mazzoli, 2011;Tansi et al, 2007;Van Dijk et al, 2000;Zecchin et al, 2013Zecchin et al, , 2015. During the Quaternary, a predominant extension phase affected the western domain of the Calabrian Arc and controlled the evolution of the Crati Basin and Coastal Range (Fabbricatore, Robustelli, & Muto, 2014;Lanzafame & Tortorici, 1981;Muto et al, 2015).…”

The paper presents a detailed mass movement inventory map of the Licetto River basin, an intermountain catchment of 50 km 2 formed during the Quaternary in response to extensional tectonics dissecting fold-and-thrust belts of the Calabrian Coastal Range (Southern Italy). The map (Main Map) is the result of both an integration between geological and morphological data derived from the visual analysis of aerial photographs at different times and scales, and the collection of new data obtained from multi-temporal field surveys. The study area is affected by a total of 824 mass movements, frequently made by superimposed bodies of different types, states of activity and sizes, including some kilometre-scale Deep-Seated Gravitational Slope. The majority of the mapped landslides, mainly of slide type, involve low-grade metamorphic rocks which also show the exclusive presence of deep-seated gravitational slope deformations. Analysis of the inventory map revealed that 40% of the mapped landslides, often attributable to very slow-moving landslides, can be considered active. The Main Map represents a useful tool for territorial planning and engineeringgeological and environmental purposes in this complex geostructural area, providing a useful contribution for quantitative landslide risk analyses and the design of appropriate risk-mitigation measures.
