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...

We present a reliable methodology to estimate the energy associated with subaerial diffuse degassing of volcanic‐hydrothermal fluids. The fumaroles 15 structures (DDSs) located in eight volcanic systems world were sampled and analyzed. Furthermore, each area was measured for soil temperature gradients CO 2 fluxes. results show that hydrothermal or system is characterized by typical source fluid which feeds both through soil. Experimental data physical numerical modeling process demonstrate...
Long‐duration time series of the chemical composition fumaroles and soil CO 2 flux reveal that important variations in activity Solfatara fumarolic field, most hydrothermal site Campi Flegrei, occurred 2000–2008 period. A continuous increase concentrations a general decrease CH 4 are interpreted to be consequence increment relative amount magmatic fluids, rich poor , hosted by system. Contemporaneously, H O‐CO ‐He‐N gas system shows remarkable compositional samples collected after July 2000...
The peculiarity of the quiescent La Fossa volcano is occurrence “crises” characterized by strong increases fumarole T and output chemical changes indicative an increasing input magmatic fluids. Several surveys carried out during a new “crisis” began in November 2004 indicate that total diffuse CO 2 emission for crater area one order magnitude crises (up to 1600 ton·d −1 December 2005). Concern exists on possibility these be related unrest process leading eruption. repetition along decades...
In order to test the potentiality of soil CO 2 diffuse degassing measurements for study underground mass and heat transfer in geothermal systems detailed surveys were performed at Latera caldera, which is an excellent site, because abundant available subsurface data. Over 2500 flux revealed that endogenous caldera concentrates on a NE‐SW band coinciding with structural high fractured Mesozoic limestones hosting water‐dominated high‐enthalpy reservoir. The total hydrothermal from has been...
Mefite d'Ansanto, southern Apennines, Italy is the largest natural emission of low temperature CO 2 rich gases, from non‐volcanic environment, ever measured in Earth. The fed by a buried reservoir, made up permeable limestones and covered clayey sediments. We estimated total gas flux ∼2000 tons per day. Under wind conditions, flows along narrow channel producing persistent river which has killed over period time people animals. application physical numerical model allowed us to define zones...
Persistently active volcanoes emit gas continuously and may present a long-term hazard depending upon the specie, concentration levels exposure time.Following last crisis occurred at Vulcano island (Aeolian archipelago, Italy) during 2021-2022, surveillance activities carried out by personnel of Istituto Nazionale di Geofisica Vulcanologia Palermo Branch Etnean Observatory, let us to investigate state island's concerning volcanic gases considering two degassing scenarios for CO2 SO2...
Abstract Volcanic CO 2 emissions play a key role in the geological carbon cycle and monitoring of volcanic fluxes helps to forecast eruptions. The quantification is challenging due rapid dilution magmatic -rich ambient air diffuse nature many emissions, leading large uncertainties global flux inventory. Here, we report measurements using new DIAL laser remote sensing system for (CO DIAL). Two sites zone Campi Flegrei (Italy) were scanned, yielding path-amount profiles used compute fluxes....
Abstract La Fossa quiescent volcano and its surrounding area on the Island of Vulcano (Italy) are characterized by intensive, persistent degassing through both fumaroles diffuse soil emissions. Periodic crises occur, with marked increase in temperature steam gas output (mostly CO 2 ) from crater emission as well flanks base. The hazard most inhabited part island, Porto, was investigated simulating dispersion atmosphere under different wind conditions. DISGAS (DISpersion GAS) code, an...
A permanent automatic infrared (IR) station was installed at Solfatara crater, the most active zone of Campi Flegrei caldera. After a positive in situ calibration IR camera, we analyze 2175 thermal images same scene from 2004 to 2007. The includes portion steam heated hot soils Solfatara. experiment initiated detect and quantify temperature changes shallow structure quiescent volcano such as over long periods. Ambient is main parameter affecting temperatures, while air humidity rain control...
Several nonvolcanic sources in central Italy emit a large amount of carbon dioxide (CO 2 ). Under stable atmospheric conditions and/or the presence topographic depressions, concentration CO , which has molecular mass greater than that air, can reach high values are lethal to humans or animals. episodes this phenomenon were recorded and elsewhere. In order validate model for dispersion heavy gas assess consequent hazard, we applied tested code TWODEE‐2, an improved version established TWODEE...
