“…Our results are consistent with the analysis of Di Luccio et al (2018), which provided additional insights into the genesis of seismic events in this area, attributing them to tectonic loading, over-pressurized CO 2 reservoirs at upper crust depths, or intrusive episodes of magmatic sources at greater depths. A recent paper by Vitale et al (2023) also confirmed the presence of deep fluids in the area, unveiling four gas vents around the Matese Massif area (Figure 3).…”

“…White dashed and dotted lines are the contours of anomalies in the Q(p) and peak‐delay (PD) models. The CO 2 flux (Frondini et al., 2019; Vitale et al., 2023) is compared with the anomalies from the Q and PD models at 5.6 km (a, b) and 11.7 km (c, d).…”

“…Feature a 1 is in the southern Apennines and extends primarily along the Matese Massif and the Volturno Plain, bordering the volcanic area of Roccamonfina to the southwest. The area is partially characterized by high CO 2 emissions at the surface (Frondini et al., 2019; Vitale et al., 2023) (Figure 3). Anomalies a 2 and a 3 mainly extend in the southern Abruzzo region, along the Apennine axis ( a 2) and eastward, on the foothills ( a3 ).…”

“…The westernmost sector of the study area comprises the Southern tip of the Roman Magmatic Province. This sector is characterized by diffuse volcanic phenomena such as CO 2 degassing (Frondini et al., 2019; Vitale et al., 2023) (Figure 3). Here, a high‐attenuation/high‐scattering volume coincides with the Albani Hills area, underlying the well‐known correlation between seismic attenuation and fluids sources in volcanic systems (Grab et al., 2017; Hudson et al., 2023; Schurr et al., 2003).…”

Despite the high detection level of the Italian seismic network and the risk associated with its fault networks, Central‐Southern Italy has no unique geophysical model of the crust able to illuminate its complex tectonics. Here, we obtain seismic attenuation and scattering tomography models of this area; both reveal high attenuation and scattering anomalies characterizing the entire Apenninic Chain and related to its East‐ and West‐dipping extensional Quaternary tectonic alignments. Fault‐associated fractured zones become preferential ways for circulating and degassing high‐attenuation CO2‐bearing fluids. A previously undetected fluid source area is a high‐attenuation volume below the Matese complex, while a similar smaller anomaly supports a fluid source near L'Aquila. The most prominent low attenuation and scattering volumes reveal a locked aseismic zone corresponding to the Fucino‐Morrone‐Porrara fault systems, representing a zone of significant seismic hazard.

The Irpinia Fault, also known as the Monte Marzano Fault System, located in the Southern Apennines (Italy), is one of the most seismically active structures in the Mediterranean. It is the source of the 1980, Ms 6.9, multi-segment rupture earthquake that caused significant damage and nearly 3,000 casualties. Paleoseismological surveys indicate that this structure has generated at least four Mw ~ 7 surface-rupturing earthquakes in the past 2 ka. This paper presents a comprehensive, high-resolution geophysical investigation focused on the southernmost fault segment of the Monte Marzano Fault System, i.e., the Pantano-Ripa Rossa Fault, outcropping within the Pantano di San Gregorio Magno intramontane basin. The project, named TEst Site IRpinia fAult (TESIRA), was supported by the University of Napoli Federico II to study the near-surface structure of this intra-basin fault splay that repeatedly ruptured co-seismically in the past thousands of years. Our imaging approach included 2D and 3D electrical and seismic surveys, gravimetry, 3D FullWaver electrical tomography, drone-borne GPR and magnetic surveys, and CO 2 soil flux assessment across the surface rupture. This multidisciplinary investigation improved our understanding of the basin shallow structure, providing an image of a rather complex subsurface fault and basin geometry. Seismic data suggest that fault activity at the Pantano segment of MMFS is characterized by a near-surface cumulative displacement greater than previous estimations, calling into question earlier assumptions about the timing of its activation. Despite some challenges with our drone-mounted survey equipment, the integrated dataset provides a comprehensive and reliable image of the subsurface structure. This work demonstrates the utility of developing an integrated approach at high-resolution geophysical imaging and interpretation of fault zones with weak morphological expressions.
