We present the first regional map of CO 2 Earth degassing from a large area (most central and south Italy) derived carbon deep provenance dissolved in main springs region. The investigation shows that globally significant amount deeply (10% estimated global emitted subaerial volcanoes) is released by two areas located western Italy. anomalous flux suddenly disappears Apennine correspondence to narrow band where most seismicity concentrates. Here, at depth, gas accumulates crustal traps...
In the present period of quiescence, Solfatara volcano, 1 km far from Pozzuoli, releases 1500 t d −1 hydrothermal CO 2 through soil diffuse degassing a relatively small area (0.5 ). This amount gas is comparable to that released by crater plume emissions many active volcanoes. On basis /H O ratio measured in high‐temperature fumaroles inside area, we computed total thermal energy flux 1.19×10 13 J (138 MW). Most this lost shallow steam condensation and transferred atmosphere hot area. The at...
On 6 April 2009, a M w = 6.3 earthquake occurred in the central Apennines (Italy) damaging city of L'Aquila and surrounding country. We relocate October 2008 to 2009 foreshocks about 2000 aftershocks between 30 by applying double‐difference technique determine stress field from focal mechanisms. The events concentrate upper 15 km crust. Three main NW‐SE NNW‐SSE striking, 30°–45° 80°–90° dipping faults were activated during seismic sequence. Among these, normal fault thrust reactivated with...
Deep CO2 emissions characterize many nonvolcanic, seismically active regions worldwide, and the involvement of deep in earthquake cycle is now generally recognized. However, no long-time records such have been published, temporal relations between occurrence tectonic release remain enigmatic. Here, we report a 10-year record (2009-2018) flux Apennines (Italy) during intense seismicity. The gas emission correlates with evolution seismic sequences: Peaks are observed periods high seismicity...
Metamaterials can be engineered to interact with waves in entirely new ways, finding application on the nanoscale various fields such as optics and acoustics. In addition, acoustic metamaterials used large-scale experiments for filtering manipulating seismic (seismic metamaterials). Here, we propose isolation based a device that combines some properties of (e.g., periodic mass-in-mass systems) standard foundation positioned right below building purposes. The concepts which this solution is...
The Aeolian volcanoes are located between the Southern Tyrrhenian Sea back arc and Calabrian Arc forearc region. Structural, geochemical seismological data indicate that early phases of volcanic activity (1.3 Myr) developed in western sector along WNW‐ESE tear faults controlling southeastward migration forearc–back system. This magmatism ceased when delamination processes affected Arc. At 0.8 Myr, volcanism migrated concentrated on “new” formed NNW‐SSE related to postsubduction extensional...
Despite their importance for eruption forecasting the causes of seismic rupture processes during caldera unrest are still poorly reconstructed from images. Seismic source locations and waveform attenuation analyses earthquakes in Campi Flegrei area (Southern Italy) 1983-1984 have revealed a 4-4.5 km deep NW-SE striking aseismic zone high offshore Pozzuoli. The lateral features principal axis anomaly correspond to main ground uplift unrest. swarms correlate space time with fluid injections...
Four sites in the western sector of Lipari Island with still active hydrothermal activity are here considered. The petrography (mesoscopic observations and XRPD) geochemistry (major, minor trace elements chemistry) ten representative extremely altered volcanic rocks were characterized. Two types parageneses discriminable, one rich silicate phases (opal/cristobalite, montmorillonite, kaolinite, alunite hematite) sulphates (gypsum, plus amounts anhydrite or bassanite). silicate-rich SiO2,...
Two months of continuous records from 40 three-component nodal stations deployed late October to December 2023 are used reveal the subsurface structure down 2 km depth beneath Salina Island, in Tyrrhenian Sea (southern Italy). We present first 3D shear wave velocity model a relatively small island ~26 km2 areal extension derived by ambient noise tomography. calculate Green’s functions for vertical components and anti-causal causal were manually separately inspected obtain group...
ABSTRACT A structural analysis carried out on the volcanic products of islands Salina, Lipari and Vulcano (Aeolian archipelago) points that large‐scale tectonic setting is dominated by NW‐SE trending right‐lateral extensional strike‐slip faults N‐S to NE‐SW normal fractures. This fault pattern generates pull‐apart type structures, developing between different right‐hand overlapping segments a characteristic imbricate fan geometry at tip major faults. All representing surface expression an...

Abstract The Aeolian volcanism ( c. 1 Ma active) develops within the Africa–Eurasia convergence setting, which is characterized by subduction of Ionian plate below Calabrian Arc. Deep earthquakes occur to east a tear fault that divides Islands into two sectors: (a) an eastern sector active volcanism, reduced crustal thickness, high seismic flux, low P-wave velocity (Vp) and attenuation (Qp) NE–SW extension; (b) western where NNW–SSE compressive strain along WNW–ESE-striking system acting....
