A two-dimensional active seismic experiment was performed on Mount Vesuvius: Explosive charges were set off at three sites, and the signal along a dense line of 82 seismometers recorded. high-velocity basement, formed by Mesozoic carbonates, identified 2 to 3 kilometers beneath volcano. slower ( P -wave velocity V ≃ 3.4 3.8 per second) shallower zone underlies central part Large-amplitude late arrivals with dominant horizontal wave motion low-frequency content as S phase converted depth...
Abstract In this work we investigate the crustal and tectonic structures of Central Tyrrhenian back‐arc basin combining refraction wide‐angle reflection seismic (WAS), gravity, multichannel (MCS) data, acquired during MEDOC (MEDiterráneo OCcidental)‐2010 survey along a transect crossing entire from Sardinia to Campania at 40°N. The results presented include ~450 km long 2‐D P wave velocity model, obtained by traveltime inversion WAS coincident density MCS poststack time‐migrated profile. We...
An extended marine, active seismic survey has been performed on September, 2001 in the gulfs of Naples and Pozzuoli by recording about 5000 shots at a network 62 sea bottom 72 shore seismographs. 3‐D images shallow caldera structure are obtained from tomographic inversion 77000 first P arrival times using Benz et al.

This interdisciplinary study on the subsurface stratigraphy of Po Plain (northern Italy) brings new evidence in support a climate‐driven erosional unloading Alps since Middle Pleistocene. A newly acquired, high‐resolution seismic profile and critical review industrial lines were integrated with sedimentologic observations four magnetostratigraphically dated continental cores to reconstruct three‐sequence evolution Pleistocene clastic infill northern basin. During first sequence (PS1;...
Geophysical data from the MEDOC experiment across Northern Tyrrhenian backarc basin has mapped a failed rift during extension of cratonic Variscan lithosphere. In contrast, Central have revealed presence magmatic accretion followed by mantle exhumation after continental breakup. Here we analyse transect E–F, which extends Sardinia to Campania margin at 40.5°N, define distribution geological domains in transition complex extended crust Tyrrhenian. The and uppermost structure along this...
Carbonate ramp systems present significant seismic interpretation challenges due to their pronounced facies heterogeneity, which frequently results in chaotic outputs that obscure underlying geological structures. The Porto Badisco Calcarenite Salento, Southern Italy, an Oligocene carbonate ramp, serves as the case study for this research, offering analogue understanding similar systems. By integrating fieldwork, laboratory analysis, and Matlab modelling, pioneers use of detailed...
Extension of the continental lithosphere leads to formation rift basins and ultimately may create passive margins. The mechanisms that operate during early stage crustal extension are still intensely debated. We present results from coincident multichannel seismic wide‐angle profiles transect across northern Tyrrhenian Sea Basin. cross Corsica Basin (France) Latium Margin (Italy) where early‐rift basin is well preserved. found two domains, each with a distinct tectonic style, heat flow...
We present a singular value decomposition (SVD) based algorithm for polarization filtering of triaxial seismic recordings on the assumption that particle motion trajectory is essentially 2-D (elliptical polarization). The filter sum first two eigenimages SVD signal matrix. Weighing functions, which are strictly dependent intensity (linearity and planarity) polarization, applied. efficiency tested synthetic traces real data, found to be superior solely covariance‐based algorithms. Although...

The dynamic non-linearity behavior affecting soils during earthquakes is a critical factor that can significantly influence seismic response, particularly when combined with site effects. Understanding this phenomenon essential for risk mitigation, especially in areas active tectonics like the Central Apennines valleys, including Norcia basin, which focus of study. These flat often host industrial and historical urban centers, increases need effective reduction strategies.This research aims...
In this study, we present the results of 76 Horizontal-to-Vertical Spectral Ratio (HVSR) measurements carried out near three active fault lineaments on eastern flank Mt. Etna (Santa Tecla-Linera, Fiandaca and Trecastagni). area, earthquakes are very shallow (within 2 km depth) produce surface fracturing deformations around identified emerging zones, even for moderate magnitude (Mw > 3.5), leading to widespread damage  buildings. Therefore, accurately identifying zones...
Abstract Explosion, earthquake, and ambient noise recordings were collected at the eastern edge of a Pliocene sediment-filled valley, nearby town San Casciano dei Bagni (Tuscany, Central Italy). The anomalous amplification amplitudes (as high as factor 20 between sediment hard-rock sites) shown by classical spectral ratios compared with results obtained using non-reference-site techniques, like that Nakamura (1989) its receiver-function-like extension. explosion data in June 1990, part...
