“…The Palizzi area lies on an underlying cold aquifer receiving the cold meteoric recharge mainly from the Piano area 1 , 44 . The Levante Bay area lies on an underlying powerful thermal and saline aquifer, which is recharged by waters of both meteoric and sea origin, and which has strong buffering power 45 , 46 .…”

The active cone of La Fossa is a close conduit volcano characterized by solphataric activity, manifested by discharging fluids through fumaroles and soil degassing. Since 1978 several degassing crises have been observed and interpreted as early signals of volcanic unrests. Recently, from June 2021 to May 2022, we measured the changes in soils CO2 release to evaluating the level and duration of the actual exhaling crises. The CO2 output has been evaluated by surveys carried out in anomalously degassing areas, located both in the La Fossa cone summit area and in other peripheral zones, coupled to near-real time monitoring data acquired by three automated stations. The strong and deep input of volatiles released from an underlying magma batch modified the chemical composition of the shallow plumbing system, bringing the system to a higher level of CO2 total pressure. This work highlights that a geochemical networks of stations, located at some distance from the fumaroles release and/or from eruptive conduits, is useful and can be applied to characterizing and monitoring any other active volcanic system. This type of studies can be useful to contribute to forecast the next evolution of the studied systems.

“…REE patterns in natural water result from four main factors that depend on the pH and redox conditions (Lewis et al, 1997;Inguaggiato et al, 2015;Oliveri et al, 2019): i) the intensity of the water-rock interaction that defines the element concentration in the fluid; ii) the formation of complexes; iii) the incorporation of REE into the structure of secondary mineral precipitates; and iv) the adsorption of REE onto minerals surfaces. Particularly, in the CCVC rocks, the REE patterns normalize by chondrite are very similar to the normalize continental crust patterns (Varekamp et al, 2006;Roulleau et al, 2018).…”

“…At Baia di Levante, fumaroles are fed by a shallow hydrothermal aquifer heated by magmatic gases [39][40][41][42][43][44][45][46][47][48][49]. The distribution of the natural fluid discharges is strongly affected by the local fracture network [50].…”

In a volcanic area, the composition of air is influenced by the interaction between fluids generated from many different environments (magmatic, hydrothermal, meteoric, and marine). Any physical and chemical variation in one of these subsystems is able to modify the outgassing dynamic. The increase of natural gas hazard, related to the presence of unhealthy components in air, may depend on temporary changes both in the pressure and chemical gradients that generate transient fluxes of gases and can have many different causes. Sometimes, the content of unhealthy gases approaches unexpected limits, without clear warning. In this case, an altered composition of the air can be only revealed after accurate sampling procedures and laboratory analysis. The investigations presented here are a starting point to response to the demand for a new monitoring program in the touristic area of Baia di Levante at Vulcano Island (Aeolian archipelago, Italy). Three multiparametric geochemical surveys were carried in the touristic area of Baia di Levante at Vulcano Island (Aeolian archipelago, Italy) in 2011, 2014, and 2015. Carbon dioxide (CO2) and hydrogen sulfide (H2S) are the main undesired components, usually present at the local scale. Anomalous CO2 and H2S outputs from soil and submarine bubbling vents were identified; the thermal anomaly of the ground was mapped; atmospheric concentrations of CO2 and H2S were measured in the air 30 cm above the ground surface. Atmospheric concentrations above the suggested limits for the wellbeing of human health were retrieved in open areas where tourists stay and where CO2 can accumulate under absence of wind.
