Introduction
I have an interest in upper crustal tectonic processes that interact with basin evolution, magmatic activity and volcanic eruptions. I used various methods. My current concerns are: Tectono-stratigraphic evolution of the Central Mediterranean backarc basins; Volcano-tectonics of the Vesuvius and Campi Flegrei active volcanoes. I teach "Structural Geology" and "Field Geology" courses.

Article
The position of the middle-upper Miocene volcanic arc, encompassing the Maghrebides, the Sardinia Channel and the Sardinia-Corsica block, implies that the Algerian and Tyrrhenian basins developed, respectively, as backarc and forearc extensional zones in the Western-Central Mediterranean. The opening of the Western-Central Mediterranean Neogene ext...

Structural pattern of the investigated area, 3-D geological models an...
Chapter
Most of the research works that aim at explaining the relationships between tectonic and volcanism focused a single volcano or eruption. Conversely, this study investigated offshore and onshore areas of the Campania margin in terms of stratigraphy, tectonics, and volcanism at a regional scale. We documented and reconstructed the three-dimensional g...

The direction of extension and the architecture of the Messinian basins of the Central Mediterranean region is a controversial issue. By combining original stratigraphic analysis of wells and seismic profiles collected offshore and onshore Calabria, we reassess the tectonic evolution that controlled the sedimentation and basement deformation during...
Article
The Marsili Basin (in the southern Tyrrhenian Sea), whose mode of extension is still a controversial issue, is the youngest bathyal basin of the Central Mediterranean. A thin sedimentary cover in the basin permits to image basement fabric and structure by swath mapping and seismic reflection data. We investigate the crustal structure of the souther...
Article
In the Central Mediterranean the Africa-Eurasia convergence led to the development of complex orogenic systems and backarc basins. Throughout Pliocene-Quaternary times the Southern Apennines accretionary prism migrated towards the Apulia foreland and, contemporaneously, the Tyrrhenian Sea backarc basin opened. In this study, we investigated the off...

The southern Apulia foreland recorded a strong (Imax=X MCS) earthquake in 1743 and a concomitant tsuna- mi, which struck the southeastern Salento coast. The seismo- genetic fault and the triggering factors of the tsunami are un- known. Three-dimensional interpretation of multichannel seismic profiles calibrated by wells using a GIS software en- abl...
Article
Miocene extensional sedimentary basins are being increasingly recognized in Central Mediterranean. However the paleogeographic reconstruction of the Paleo-Tyrrhenian during this time span results a difficult task because the subsequent Pliocene-Quaternary backarc opening moved away these older sedimentary basins. Our study outlines principal deform...
Conference Paper
In the recent decades many studies have been carried out on rift formation, in order to understand causes and modes of whole lithospheric extension. Extensional basins have been studied and classified using 2D geological sections and thus also modelled prevalently in 2D. However, the complete process of continental break-up can be understood only t...
Article
In this study, we describe the mode of extension of the Vavilov, a fossil backarc basin, triangle-shaped (approximately 240. km-wide and 200. km-long), located between Sardinia margin to the west and Campania margin to the east. We combine the analysis of recent geophysical and geological data, in order to investigate the relationship between the c...

Active extensional faulting and sedimentation are linked during basin evolution because tectonics controls the creation of the accommodation space, the sediment supply and the variation of the rate between subsidence and sedimentation. Depositional sequence mapping is a powerful technique that assists the interpretation of basin evolution on contin...
Conference Paper
Submarine vicinities of volcanoes are an important source of data for the study of the physical interaction between volcanic flows and seawater and for the evaluation of the coastal hazards. A traditional example of this interaction is from the Krakatau volcano where throughout the 1883 volcanic eruption, in a period of 2 days, a series of pyroclas...
Article
Vesuvius is an active volcano that has been affected by late Quaternary lateral collapses and tectonic faults. Cryptodomes and two debris avalanche, 18 ka-old DA1 and 3.5 ka-old DA2, were previously documented off Vesuvius and for the younger avalanche a link between onshore and offshore stratigraphy was recon- structed. The interpretation of seism...

The effects of wrenching in a given fault zone include: rotation of fault-bounded blocks leaving subsiding graben between them and along the border faults of the shear corridor, and slight compression between blocks with uplift zones between block sides and drag folds. The Campania continental margin is located between 40° and 41°N latitude on the...
Article
Catastrophic landslides associated with eruptions are a normal event in the life of many volcanoes. Slope failure of major portions of a volcanic edifice can trigger explosive activity by the sudden pressure release of hydrothermal-magmatic systems. Pumiceous pyroclastic flows are often erupted late in the paroxymal phase of eruptions associated wi...
