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:

Carbon Dioxide Emissions from Subaerial Volcanic Regions: Two Decades in Review
Cynthia Werner,Tobias Fischer,Alessandro Aiuppa,Marie Edmonds,Carlo Cardellini,Simon Carn,Giovanni Chiodini,Elizabeth Cottrell,Mike Burton,Hiroshi Shinohara,Patrick Allard +10 more
TL;DR: In this article, the authors quantify the current volcanic flux of carbon to the atmosphere and understand the factors that control this flux, which is of fundamental importance for stabilization of atmospheric CO2 and for long-term climate.

Generation of CO2-rich melts during basalt magma ascent and degassing
Michel Pichavant,Michel Pichavant,Ida Di Carlo,Silvio G. Rotolo,Silvio G. Rotolo,Bruno Scaillet,Bruno Scaillet,Alain Burgisser,Nolwenn Le Gall,Nolwenn Le Gall,Caroline Martel,Caroline Martel +11 more
TL;DR: In this paper, the authors stress the importance of bubble nucleation and growth, and of volatile diffusivities, for basaltic melt degassing, and show that CO2-oversaturated melts can be generated as a result of magma decompression.

Hydrogen in the gas plume of an open‐vent volcano, Mount Etna, Italy
Alessandro Aiuppa,Alessandro Aiuppa,Hiroshi Shinohara,Giancarlo Tamburello,Gaetano Giudice,Marco Liuzzo,Roberto Moretti +6 more
TL;DR: In this article, the first hydrogen determinations in the volcanic gas plume of Mount Etna, in Italy, were obtained during periodic field surveys on the volcano's summit area with an upgraded MultiGAS.

Overview of the precursors and dynamics of the 2012-13 basaltic fissure eruption of Tolbachik Volcano, Kamchatka, Russia
TL;DR: In this article, a broad overview of the 2012-13 flank fissure eruption of Plosky Tolbachik Volcano in the central Kamchatka Peninsula is presented, which lasted more than nine months and produced approximately 0.55 km3 DRE (volume recalculated to a density of 2.8 g/cm3) of basaltic trachyandesite magma.

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.

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.

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.

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.
