TLDR
In this article, the authors used the MultiGAS technique to provide the best documented record of gas plume discharges from Stromboli volcano to date, and showed that Strombolian's gases are dominated by H2O (48−98−mol); mean, 80%), and by CO2 (2−50−mol%; mean, 17%) and SO2 (0.2−14−mol; mean, 3%).About:

An interpretative view of open-vent volcanoes
Sylvie Vergniolle,Nicole Métrich +1 more
TL;DR: In this article , the authors provide an interpretative overview of the main characteristics of open-vent volcanoes on the basis of selected examples chosen to be representative of the diversity of their magma composition, their eruptive activity and their geodynamic context.

Influence of volcanic activity on the quality of water collected in roof water catchment systems at Stromboli Island (Italy)
TL;DR: In this paper, the results of a study carried out at Stromboli Island, a small but densely populated active volcanic area in the South of Italy, revealed clear clues of a contamination with gases and suspended particles of volcanic origin, even if the values of those contaminants considered by the World Health Organization as dangerous for human health are always below the maximum admitted concentration (MAC).
Dissertation
Determination of degassing patterns in volcanic systems
TL;DR: In this article, the effect of different permeabilities and pressure gradients within a volcanic edifice have on the degree and pattern of the gas velocity was investigated. But the authors focused on the effect that the country rock and dome are important and it is the relative permeabilities, rather than the actual values which determine the pressurisation.

Comment on ‘Conduit convection, magma mixing, and melt inclusion trends at persistent degassing volcanoes’ by Fred Witham, published in Earth Planetary Science Letters (2011) 301, 345–352
TL;DR: In this article, the influence of mixing on the CO 2 -H 2 O behavior in magmas was discussed and witham's model does not fit our melt inclusion data set for Mt Etna and Stromboli.

Mafic magma feeds degassing unrest at Vulcano Island, Italy
Alessandro Aiuppa,Marcello Bitetto,Sergio Calabrese,Dario Delle Donne,Joao Lages,Francesco Paolo La Monica,Giovanni Chiodini,Giancarlo Tamburello,Adam Cotterill,Paolo Fulignati,Anna Gioncada,Emma J. Liu,Roberto Merletti,E. Pistolesi +13 more
TL;DR: In this article , the authors use volcanic gas measurements, in combination with melt inclusion information, to propose that heightened sulphur dioxide flux during the intense fall 2021 La Fossa unrest is sourced by degassing of volatile-rich mafic magma.

Journal ArticleDOI
The compositional dependence of the saturation surface of H2O + CO2 fluids in silicate melts
TL;DR: Papale et al. as mentioned in this paper applied thermodynamic equilibrium between gaseous and liquid volatile components to model the volatile saturation surface in H 2 O−CO 2 -silicate melt systems.
Journal ArticleDOI
Volatile Abundances in Basaltic Magmas and Their Degassing Paths Tracked by Melt Inclusions
Nicole Métrich,Paul J. Wallace +1 more
TL;DR: The abundances of CO2, H2O, S and halogens dissolved in basaltic magmas are strongly variable because their solubilities and ability to be fractionated in the vapor phase depend on several parameters such as pressure, temperature, melt composition and redox state as mentioned in this paper.
Journal ArticleDOI
Melt inclusion record of the conditions of ascent, degassing, and extrusion of volatile-rich alkali basalt during the powerful 2002 flank eruption of Mount Etna (Italy)
TL;DR: In this article, the authors decipher the origin and mechanisms of the second eruption from the composition and volatile (H2O, CO2, S, Cl) content of olivine-hosted melt inclusions in explosive products from its south flank vents.
Journal ArticleDOI
Petrologic Reconstruction of Magmatic System Variables and Processes
Jon D Blundy,Kathy Cashman +1 more
TL;DR: In this article, the authors present some of the current petrological techniques that can be used for studying eruptive products and for constraining key magmatic variables such as pressure, temperature, and volatile content.

Magmatic Gas Composition Reveals the Source Depth of Slug-Driven Strombolian Explosive Activity
Mike Burton,Mike Burton,Mike Burton,Patrick Allard,Patrick Allard,Patrick Allard,F. Murè,F. Murè,F. Murè,Alessandro La Spina,Alessandro La Spina,Alessandro La Spina +11 more
TL;DR: Spectroscopic measurements performed during both quiescent degassing and explosions on Stromboli volcano are used to demonstrate that gas slugs originate from as deep as the volcano-crust interface (∼3 kilometers), where both structural discontinuities and differential bubble-rise speed can promote slug coalescence.
