“…Their structures and lithologies are different and relevant to distinct earlier evolutions. A unique characteristic of the Calabrian forearc is a pervasive continental fragment involved in tectonic events, such as the Variscan and Alpine collisions, which predate the Calabrian rollback but were critical in setting the stage for it (e.g., Filice et al, , ). A much more recent tectonic reorganization also distinguishes the Calabria forearc.…”

The Pollino Massif is the most southeastern outcrop of the Apennine core. It marks the transition between Apenninic shortening and extension, respectively, SE and NW of the massif and is also the cusp of a southeastward plunge that characterizes the submerged Apennines. The SE limit of NE‐SW extension merges with the east limit of Tyrrhenian extension in Calabria. This strategic position is expected to transition southeastward in the progressive oblique collision of the Calabrian forearc and Apulia. We test this hypothesis using published results and new field data. The time‐transgressive emergence of basins on the Apennine thrust wedge is quantitatively consistent with the ESE rollback of the Calabrian arc. Specifically, a thrust‐normal slip reversal on a SW dipping fault is responsible for the tectonic collapse that lead to the Mercure Basin along strike NW of the Pollino Massif and to an east‐to‐west reversal of drainage. This reversal is timed by an intermediate stage of trapped internal drainage with Mid‐Pleistocene lacustrine sedimentation, but it may young to SE as the normal displacement on the border fault decreases gradually to SE and vanishes near the apex of the massif. On the SE side of the massif, contractional tectonics persists at least into the Mid‐Pleistocene and likely later, while NE‐SW extension is absent. Prominent normal faults in that area accommodate range‐parallel extension and are coupled with the thrust faults. The combination of longitudinal extension with a counterclockwise rotation of hanging‐wall units and thrust directivity can account for the final setting in the Apennines.

“…It is generally referred to the western edge of the "Apenninic Platform", a thick (>4 km) carbonate shelf, that underwent compression during the Middle-Late Miocene times and was translated over an eastern basinal domain (Lagronegro-Molise basin; Patacca and Scandone 2007;Vezzani et al 2010 and references therein). From the bottom to the top, the bedrock succession includes late Triassic dolostones, Cretaceous limestones, and Paleocenic-Lower Miocenic calcarenites cross-cut by the pillow lava basalts belonging to Liguride units of the northern sector of Calabrian arc (Quitzow 1935, Grandjaquet and Grandjaquet 1962, Amodio Morelli et al 1976, Ghisetti and Vezzani, 1983Iannace et al 2004Iannace et al , 2005Iannace et al and 2007Liberi et al 2006;Filice et al 2015 andTangari et al 2018).…”

Abstract. With the aim of unveiling evidence of Late Quaternary faulting, a series of Ground Penetrating Radar (GPR) profiles were acquired across the Campotenese continental basin (Mt. Pollino region) in the southern Apennines active extensional belt (Italy). A set of forty-nine 300 MHz and 500 MHz GPR profiles, traced nearly perpendicular to a buried normal fault, were acquired and carefully processed through a customized workflow. The data interpretation allowed us to reconstruct a pseudo-3D model depicting the boundary between the Mesozoic bedrock and the sedimentary fill of the basin, which were in close proximity to the fault. Once reviewing and defining the GPR signature of faulting, we highlight in our data how near surface alluvial and colluvial sediments appear to be dislocated by a set of conjugate (west and east-dipping) discontinuities that penetrate inside the underlying Triassic dolostones. Close to the contact between the continental deposits and the bedrock, some buried scarps which offset wedge-shaped deposits are interpreted as coseismic ruptures, subsequently sealed by later deposits. Although the use of pseudo-3D GPR data implies more complexity linking the geophysical features among the radar images, we have reconstructed a reliable subsurface fault pattern, discriminating master faults and a series of secondary splays. We believe our contribution provides an improvement in the characterization of active faults in the study area which falls within the Pollino seismic gap and is considered potentially prone to severe surface faulting. Our aim is for our approach and workflow to be of inspiration for further studies in the region as well as for similar high seismic hazard areas characterized by scarcity of near-surface data.

“…The geological setting of the study area is characterized by the presence of different basement units, each with a different tectono-metamorphic evolution arranged in a nappe-pile stack, forming an allochthonous tectonic building piled up in the Oligocene -Lower Miocene (Amodio-Morelli et al, 1976;Cirrincione et al, 2015;Filice et al, 2015;Ortolano, Cirrincione, Pezzino, Tripodi, & Zappala, 2015;Tansi, Muto, Critelli, & Iovine, 2007;Van Dijk et al, 2000), which overthrusted the Mesozoic carbonate Unit of Apennine affinity ( Figure 2). The lower plate outcrops along the Coastal Range in several tectonic windows (Figure 2 (A)), among these the most extensive is represented by the Mt.…”

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.
