Il terremoto di Messina del 1908 in un modello sismotettonico della Sicilia settentrionale e del Basso Tirreno.
New seismological, structural and marine geology constraints for a seismotectonic model of the hinge zone between northern Sicily and southern Tyrrhenian
Middle-Late Pleistocene marine terraces and fault activity in the Sant’Agata di Militello coastal area (north-eastern Sicily)
Abstract The coastal sector of Sant’Agata di Militello (north-eastern Sicily) is characterized by a flight of raised Middle-Upper Pleistocene marine terraces occurring at different heights with respect to present sea level. In particular, the geomorphological survey and the analysis of stereo-pairs of aerial photographs allowed to recognize at least five main orders of well preserved Quaternary surfaces and relative deposits mostly located at the hanging wall and at the footwall of the Pleistocene northwest-dipping Capo d’Orlando normal fault, which controlled the geomorphological evolution of the coastal area. The marine terraces show an overall good morphological continuity and are formed…
An integrated approach to investigate the seismotectonics of northern Sicily and southern Tyrrhenian
Abstract This paper deals with a comparison among recent structure and seismicity in the hinge zone between northern Sicily and southern Tyrrhenian, corresponding to both emerged and submerged northern portion of the Maghrebian chain. This hinge zone is part of a wider W–E trending right-lateral shear zone, mainly characterized by both a synthetic NW-SE/W–E oriented, and antithetic left-lateral N–S/NE-SW fault systems, which has been affecting the tectonic edifice, since the Pliocene. The inland structures have been mapped using aerial-photo interpretation, geological mapping and mesostructural analysis to reconstruct the stress regime in the study area. On the contrary, the offshore struct…
Evoluzione strutturale del settore costiero compreso tra Acquedolci e Capo d’Orlando (Sicilia settentrionale) con l’ausilio di analisi morfotettoniche
Una ricostruzione dell' ordine sequenziale delle deformazioni nel margine settentrionale della Sicilia e implicazioni sismotettoniche.
Vincoli geologico-strutturali per un modello sismotettonico in condizioni di defomazione non coassiale, nell’area del Tirreno meridionale-Sicilia settentrionale
Relationships between seismicity and tectonic in northern Sicily and southern Tyrrhenian: some important open problems.
A contribution to a seismotectonic model of the hinge zone between northern Sicily and southern Tyrrhenian by some seismological and structural constraints
An integrated research on the hinge zone between northern Sicily and its Tyrrhenian off-shore has been carried out, by means of structural, seismological and statistical analyses. The main structural features of the area are represented by both NWSE to W–E striking right-lateral and N–S to NE-SW striking leftlateral fault systems, responsible of uplifting (restraining) and subsiding (releasing) zones. Within this hinge zone the seismicity is mainly located between 10 and 20 km of depth and clustered according to the orientation of the outcropping fault systems. The brittle strain partitioning related to a right-lateral simple shear zone has been reconstructed in the onshore sector, while in…
