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:

Effects of CO 2 flushing on crystal textures and compositions: experimental evidence from recent K-trachybasalts erupted at Mt. Etna
TL;DR: In this paper, a series of experiments were conducted to understand the response of magmas from Etna volcano to CO2 flushing, showing that flushing of a CO2-rich fluid phase leads to an increase of the amount of clinopyroxene and a decrease of the abundance of plagioclase at 300MPa.

Radar Path Delay Effects in Volcanic Gas Plumes: The Case of Láscar Volcano, Northern Chile
TL;DR: This work investigates the radar path delays that were generated by water vapor contained in the volcanic gas plume of the persistently degassing Láscar volcano, which is located in the dry Atacama Desert of Northern Chile and shows thatGas plume related refractivity changes are significant and detectable in DInSAR measurements.

TL;DR: The ordinarily benign activity of basaltic volcanoes is periodically interrupted by violent paroxysmal explosions ranging in size from Hawaiian to Plinian in the most extreme examples as mentioned in this paper.

Increasing Summit Degassing at the Stromboli Volcano and Relationships with Volcanic Activity (2016-2018)
TL;DR: The last increased volcanic activity of the Stromboli volcano, from 2016 to 2018, was characterized by increases in the number and frequency of crater explosions and by episodes of lava overflow.

TL;DR: In this article, the authors place the first constraints on the mobilisation of toxic elements from volcanic ash, which are necessary to assess the associated potential health risk of volcanic areas, and they have performed leaching experiments on the fine (

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

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.
