CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishGeological, gravimetric, and seismological data from the central-eastern Sicily (Italy) provideevidences of a NW-SE oriented shear zone at the southern edge of the Ionian subduction system. Thisstructure consists of a near 100 km long lithospheric-scale structural and seismic boundary. In thenear-surface, it shows Plio-Pleistocene vertical-axis structural rotations, kilometer-scale topographicimprint, progressive wrenching, and large down-faulting. All these features, together with its locationsouth-west of the subduction system, allow us to interpret the shear zone as the upper plate expression ofan abandoned Subduction Transform Edge Propagator fault, working before slab detachment, currentlyreactivated by elastic rebound or mantle upwelling mechanism triggered by slab detachment, to forman incipient transform belt separating compartments characterized by different motion in the moderncontext of Africa-Europe convergence.
