Geophysical investigations along the Tyrrhenian shore of Calabria

Risultato della ricerca: Meeting Abstractpeer review


The Tyrrhenian Sea is a widely investigated basin developed in the Mediterranean area within the frame of Europe-Africa convergence and Ionian plate subduction process (Faccenna et al., 2014; Orecchio et al., 2014 and referencestherein). Since the Late Miocene, extension within the Tyrrhenian Sea was associated with coeval shortening in theApennines-Maghrebide orogen and progressive southeastward rollback of the Ionian subducting plate. In this frameworkboth extension and widespread volcanism well represented by the Vavilov and Marsili basins and the Aeolian volcanicarc, are typical features of the Tyrrhenian Sea region. Several authors (De Ritis et al., 2010; Loreto et al., 2015 andreferences therein) have also recently documented the occurrence of a submarine volcanic structure in proximity of theTyrrhenian shore of southern Calabria just near the Capo Vaticano promontory. Geophysical and geochemical data haveprovided new insights on the volcano-tectonic origin and geometry of this volcanic structure formed in the upper plate ofthe Ionian subduction system. On these grounds, the present study aims to investigate the southeastern portion of theTyrrhenian Sea and the confining western Calabrian area by integrating new results coming from local earthquaketomography, high-resolution reflection seismic and magnetic data. The joint evaluation of the different results will allowto further refine the knowledge of the Capo Vaticano volcanic structure. Moreover, we aim to discuss the possibleoccurrence of further events along a wider portion of the western Tyrrhenian Calabrian side, extended in between 38° and40° of latitudes, on the base of previously undetected geophysical anomalies, potentially related to volcanic-intrusivemanifestations.
