“…Regardless of the number of sequences, the key question manly concerns the age of the base of the Crati Basin infilling and, hence, the presence/absence of the "mid-Pliocene unconformity" of Zecchin et al (2015). In this regard, geological data (Lanzafame & Tortorici 1981;Barone et al 2008;Robustelli et al 2009) and palaeontological analysis (Lanzafame & Tortorici 1981;Corbi et al 2009;Fabbricatore 2011; al.…”

“…The Crati Basin is filled by Plio-Pleistocene deposits that can be divided into two (Lanzafame & Tortorici 1981;Fabbricatore et al 2014) or three main depositional sequences (Spina et al 2011;Zecchin et al 2015) bounded by a regional angular unconformity.…”

“…They controlled the migration of the Calabrian Arc and experienced episodes of extension (Van Dijk et al 2000), responsible for the dissection of the Calabrian Arc (Lanzafame & Zuffa 1976;Lanzafame & Tortorici 1981;Tortorici 1981; Knott & Turco 1988;Turco et al 1990;Tortorici et al 1995;Schiattarella 1998;Cifelli et al 2006;Tansi et al 2007). This resulted in an alternation of morphostructural ridges and Plio-Quaternary tectonic depressions bounded by high-angle fault scarps (Fabbri et al 1981;Barone et al 1982;Argani & Trincardi 1993;De Rosa et al 2002;Milia et al 2008;Filocamo et al 2009;Robustelli et al 2005Robustelli et al , 2009Pepe et al 2010;Spina et al 2011;Tripodi et al 2013;Longhitano et al 2014;Robustelli et al 2014;Zecchin et al 2015).

Abstract:In this paper, we present the results of an integrated geomorphological and stratigraphical study carried out in the eastern side of the Crati River valley (northern Calabria, South Italy). This area is characterized by the occurrence of three order palaeosurfaces that, along with low-sloping palaeovalleys and structural landforms, are striking features of the landscape. The relationships between morpho-tectonic and sedimentary evolution of the Crati Basin has been assessed through sandstone detrital modes, morphostratigraphy and geomorphological correlation with adjacent areas. The two main unconformity surfaces that typify the Quaternary fill were correlated to different steps of landscape evolution. The presence of both erosional and depositional palaeosurfaces has been a useful marker for reconstructing sedimentary and morphogenetic events, and hence to detect drainage network evolution and changes in source sediment area. In particular, we recognized that the study area experienced, during the late Pliocene-Early Pleistocene a period of subaerial landscape modelling as suggested by low-sloping palaeovalleys and related fluvial deposits (1 st Order Palaeosurface). At that time, the source of the detrital constituents of the PPS Unit sandstones was mainly from the Sila Massif. The onset of Coastal Range identification and uplift (Early Pleistocene) marks a change in the geomorphic scenario with tectonic driven stream incision and valley development along the eastern side of Coastal Range, along with the occurrence of depositional and erosional landsurfaces (2 nd Order Palaeosurface) at footslopes. During this period, the Coastal Range and Sila Massif were the sources for the detrital constituents of the PlS Unit sandstones. The progressive uplift of Coastal Range during late Early Pleistocene and the marked backstepping of the depositional systems along the Sila footslope was accompanied by alternating phases of down-cutting and base-level stability resulting in the development of a step-like distributed 3 rd Order Palaeosurface. The presence of dolostone in detrital modes is clear evidence of stream piracy phenomena of ancient palaeovalleys by the Crati valley-facing drainage network.

“…Further, sedimentation proceeds eastwards, causing a diachronous transgression, propagating the progressive onlap on the western Sila Massif slope. The deposits are constituted of conglomerates, sandstones and mixed arenites mostly belonging to deltaic and coastal deposits (Carobene & Damiani, 1985;Colella, 1988;Colella, De Boer, & Nio, 1987;Fabbricatore et al, 2014) and compare to the same coeval successions of other basins bordering the eastern and southern margins of the Sila Massif Longhitano, Chiarella, & Muto, 2014;Muto et al, 2015;Zecchin et al, 2012Zecchin et al, , 2013aZecchin et al, , 2013bZecchin et al, , 2015. Starting from Middle Pleistocene, northern Calabria experienced a marked uplift (Tortorici, 1981;Westaway, 1993) that caused the deformation of the Lower Pleistocene deposits and the accumulation of a 40 m thick succession of fluvial conglomerate well exposed in the western margin of the Crati Basin; a comparable stratigraphic succession is found on the eastern side of the Sila Massif Robustelli et al, 2009 Spina, & Critelli, 2003;Robustelli, Muto, Scarciglia, Spina, & Critelli, 2005) and of the eastern Sila margin (Carobene, 2003;Ferranti, Santoro …”

The Crati Graben is a depression of Plio-Holocene age mainly controlled by extensional N-S striking faults and WNW-ESE transcurrent faults, in its northern and southern extremity. It is characterized by high landslide susceptibility due to the particular geo-structural pattern and seismotectonic characters. Landslides involve many villages, infrastructure and food crops, bringing serious economic and social damage. The seismotectonic and landslides Main Map of the Crati Graben, described in this paper, represents an update in detail of the framework of landslide risk areas and shows the main active and recent faults of the Crati Graben. The landslides and the faults, have been identified and classified, originally at detail scale (1:5000) and, then, represented at 1:50,000 scale. The geo-structural and geomorphological data were analysed in a geographic information system. The work has revealed a correlation between the trend of faults with respect to the distribution of landslides and of the historical and instrumental seismicity. The work presents an updated knowledge framework of risk conditions of the study zone, where risk areas related to slope instability are hierarchically classified according to the destructive potential of landslides. This document may be therefore a useful reference in planning and prioritising in the design of interventions for the safety of slopes and waterways.ARTICLE HISTORY
