During the reawaking of a volcano, magmas migrating through shallow crust have to pass hydrothermal fluids and rocks. The resulting magma-hydrothermal interactions are still poorly understood, which impairs ability interpret volcano monitoring signals perform hazard assessments. Here we use results physical volatile saturation models demonstrate that magmatic volatiles released by decompressing at critical degassing pressure (CDP) can drive volcanic unrest towards state. We show that, CDP,...
We present an advanced differential synthetic aperture radar (SAR) interferometry (DInSAR) processing chain, based on the Parallel Small BAseline Subset (P-SBAS) technique, for efficient generation of deformation time series from Sentinel-1 (S-1) interferometric wide (IW) swath SAR data sets. first discuss effective solution high-quality interferograms, which properly accounts peculiarities terrain observation with progressive scans (TOPS) acquisition mode used to collect S-1 IW data. These...
Since early 2021, peculiar Volcano-Tectonic (VT) seismic sequences with very short inter-event times have become increasingly frequent and evident in the Campi Flegrei caldera (Italy), which has been experiencing a long-term unrest since 2005. During same period ground deformation (uplift), seismicity gas emission that characterize current showed an acceleration. Within this type of sequence, we identify burst-like swarms, characterized by so they are often not easily recognizable. Here show...
For the first time a physical model, constrained by monitoring data, is used to derive quantitative estimate of evolution in magmatic gases that enter hydrothermal system an active volcano. The site Campi Flegrei (west Naples, Italy), caldera had large ground inflation 1982–1984 followed 20 yr subsidence. More recently behavior has changed: component fumaroles increased, swarms earthquakes are more frequent, and started general uplifting trend, indicating undergoes repeated injections fluid....
Abstract The causative source of the first damaging earthquake instrumentally recorded in Island Ischia, occurred on 21 August 2017, has been studied through a multiparametric geophysical approach. In order to investigate geometry and kinematics we exploit seismological, Global Positioning System, Sentinel‐1 COSMO‐SkyMed differential interferometric synthetic aperture radar coseismic measurements. Our results indicate that retrieved solutions from geodetic data modeling seismological are...
The Neapolitan volcanic area includes three active and high-risk volcanoes: Campi Flegrei caldera, Somma–Vesuvius, Ischia island. is a typical example of resurgent characterized by intense uplift periods followed subsidence phases (bradyseism). After about 21 years following the 1982–1984 unrest, new inflation period started in 2005 and, with increasing rates over time, ongoing. overall from to December 2019 65 cm. This paper provides history recent caldera unrest an overview ground...
<p>The Campi Flegrei caldera is an active volcanic system associated to a high risk, and represents well known peculiar example of ground deformations (bradyseism), characterized by intense uplift periods, followed subsidence phases with some episodic superimposed mini-uplifts. Ground deformation important precursor, and, its continuous monitoring, one the main tool for short time forecast eruptive activity. This paper provides overview GPS monitoring from January 2000 July 2013,...
From 2006 to spring 2013, Campi Flegrei (CF) caldera, Italy, was mostly uplifting at an increasing rate, particularly high from 2011. We show that the 2011–2013 accelerated uplift and 1980–2010 inflation deflation phases can be explained by a two-source conceptual model similar proposed Amoruso et al. (2014) (reference model). However, pressurization of sole thin quasi-horizontal ∼4000 m deep source, responsible for large-scale deformation, explain whole while activity shallower Solfatara...
Abstract The knowledge of the dynamic Campi Flegrei calderic system is a primary goal to mitigate volcanic risk in one most densely populated areas world. From 1950 1990 suffered three bradyseismic crises with total uplift 4.3 m. After 20 years subsidence, started again 2005 accompained by low increment seismicity rate. In 2012 an seismic energy release and variation gas composition fumaroles Solfatara (in central area caldera) were recorded. Since then, slow progressive increase phenomena...
A crucial feature to manage a volcanic crisis is the ability of volcanologists promptly detect an impending eruption. This often affected by significant uncertainty, mainly for difficulty in interpreting monitoring signals terms exact timing possible Here we contribute this problem, focusing on states active volcanoes with closed conduit, as deduced from data. Four main can be identified. In quiescence state 1) data lie baseline, suggesting lack shallow magma/fluid movement. The unrest...
Campi Flegrei caldera, including the extremely urbanised city of Naples, is most risky volcanic area in World. The last eruption (1538) occurred at end some decades ground uplift, superimposed to secular subsidence. During four decades, it experienced a huge uplift phase, reaching about 3.5 m 1985, when subsidence phase started. Recent geodetic data demonstrate that such has terminated, and new episode started November 2004, with low but increasing rate leading 0.04 till October 2006. A...
Since 2004, a continuous Global Positioning System (GPS) network is operated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) to investigate active tectonic processes in Italy and surrounding regions, which are still largely debated. This important infrastructure, named Rete Integrata GPS (RING) network, consists about 130 stations deployed all over Italy. The development realization of stable monumentation, integration with seismological instruments choice both satellite...
The inter-arrival times of the post 2000 seismicity at Campi Flegrei caldera are statistically distributed into different populations. low population represents swarm events, while high marks background seismicity. Here, we show that is increasing same rate (1) ground uplift and (2) concentration fumarolic gas specie more sensitive to temperature. seismic temporal increase strongly correlated with results recent simulations, modelling injection magmatic fluids in hydrothermal system. These...
Campi Flegrei is the largest active caldera in Europe and it home to more than 350,000 people. Since 2005, has shown accelerating ground inflation an intensification of seismic activity. Here we quantify decadal trend alongside oscillations various frequencies explore relationships between deformation activity over period 2000 November 2023. Results highlight major changes that have occurred last four years analyzed reveal a parabolic increase vertical uplift super-exponential...
The Campi Flegrei caldera, Italy, is considered one of the most high-risk volcanic areas on planet due to its location within metropolitan area Naples. caldera currently undergoing unrest. unrest linked an uplift phase that started in 2005, which accompanied by gas emissions and volcano-tectonic seismicity. Owing limited knowledge plumbing system pre-eruptive processes, tracking evolution a often based probabilities obtained experts’ elicitation. In this work, we present daily variation...

Understanding volcanic activity, especially unrest, is a challenging task. This complexity magnified in Napoli (Southern Italy), where the presence of nearly million people living on Campi Flegrei (CF) caldera makes invasive monitoring activities impossible to be performed. Yet, analysis coda-waves from continuous ambient-noise recordings (Shapiro &amp; Campillo, 2004) provides highly resolved in-time measurements mechanical and structural variations crust without need invasive, as also...
Abstract This study presents a new method, called the Radial Interpolation Method, to interpolate data characterized by an approximately radial pattern around relatively constrained central zone, such as ground deformation patterns shown in many active volcanic areas. The method enables fast production of short-term maps on base spatially sparse measurements and can provide uncertainty quantification interpolated values, fundamental for hazard assessment purposes source reconstruction....
Ongoing resurgence affects Campi Flegrei caldera (Italy) via bradyseism, i.e. a series of ground deformation episodes accompanied by increases in shallow seismicity. In this study, we perform mathematical analysis the GPS and seismic data instrumental catalogs from 2000 to 2020, comparison them preceding 1983 1999. We clearly identify characterize two overlying trends, decennial-like acceleration cyclic oscillations with various periods. particular, show that all signals have been...
