TLDR
In this article, the authors examined and discussed the alternative hypothesis that most of the paroxysms could be triggered and driven by the fast upraise of CO2-rich gas pockets generated by bubble foam growth and collapse in the subvolcano plumbing system.About:

Basaltic explosive volcanism: Constraints from deposits and models
TL;DR: Basaltic pyroclastic volcanism takes place over a range of scales and styles, from weak discrete Strombolian explosions (∼10 2 −10 3 ) to Plinian eruptions of moderate intensity (10 7 −10 8 ǫ −1 ). Recent well-documented historical eruptions from Etna, Kīlauea and Stromboli typify this diversity as discussed by the authors.
Journal ArticleDOI
Sulfur Degassing From Volcanoes: Source Conditions, Surveillance, Plume Chemistry and Earth System Impacts
TL;DR: This paper reviewed the causes of variability in sulfur abundance and speciation in different geodynamic contexts; the measurement of sulfur emissions from volcanoes; links between subsurface processes and surface observations; sulfur chemistry in volcanic plumes; and the consequences of sulfur degassing for climate and the environment.

The 2007 eruption of Stromboli volcano: Insights from real-time measurement of the volcanic gas plume CO2/SO2 ratio
Alessandro Aiuppa,Alessandro Aiuppa,Cinzia Federico,Gaetano Giudice,Giovanni Giuffrida,Roberto Guida,Sergio Gurrieri,Marco Liuzzo,Roberto Moretti,Paolo Papale +9 more
TL;DR: In this paper, the authors report on the results of two years of in-situ sensing of the CO 2 /SO 2 ratio in Stromboli's volcanic gas plume, in the attempt to put constraints on the trigger mechanisms and dynamics of the eruption.

A model of degassing for Stromboli volcano
Alessandro Aiuppa,Antonella Bertagnini,Nicole Métrich,Roberto Moretti,A. Di Muro,Marco Liuzzo,Giancarlo Tamburello +6 more
TL;DR: 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%).

Hawaiian and Strombolian Eruptions
TL;DR: Hawaiian and Strombolian eruptions are characteristic of silica-poor, low viscosity magmas and represent the most frequent manifestations of explosive volcanism on Earth as mentioned in this paper.

VOLATILECALC: a silicate melt-H 2 O-CO 2 solution model written in Visual Basic for excel
Sally Newman,Jacob B. Lowenstern +1 more
TL;DR: The VOLATILECALC solution models for the rhyolite-H2O-CO2 and basalt-H 2 O-CO 2 systems at magmatic temperatures and pressures below ∼ 5000 bar are presented in this paper.

Ascent and eruption of basaltic magma on the earth and moon
Lionel Wilson,James W. Head +1 more
TL;DR: In this paper, the ascent and emplacement of basaltic magma on the earth and moon is modeled by the application of geological and physical observations and constraints, provided that allowance is made for the coalescence of gas bubbles.
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.

Eruptive and diffuse emissions of CO2 from Mount Etna
Patrick Allard,J. Carbonnelle,D. Dajlevic,J. Le Bronec,P. Morel,M.C. Robe,J. M. Maurenas,R. Faivre-Pierret,D. Martin,J. C. Sabroux,P. Zettwoog +10 more
TL;DR: In this article, the authors used data collected from 1975 to 1987 to estimate carbon dioxide emissions from the summit craters and the upper flanks of the volcano and found that the average output of CO2 from summit crater degassing is 13±3 Tg yr−1, an order of magnitude higher than the annual CO2 output from Kilauea, Hawaii, and representative arc volcanoes.
