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:

Ascension et dégazage des magmas basaltiques : approche expérimentale
TL;DR: In this article, a meilleure comprehension of the dynamique d'ascension and d'eruption des magmas basaltiques is presented. Butt et al. realize des experiences de decompression a haute pression (200-25 MPa) and haute temperature (1200°C) orientees for documenter the nucleation des bulles de gaz ; this processus, which constitue the premiere andape du degazage magmatique, conditionne l’evolution de la phase gazeuse (force motrice des

Alessandro Aiuppa,Alessandro Aiuppa,Luca Fiorani,S. Santoro,S. Santoro,Stefano Parracino,Stefano Parracino,Roberto D'Aleo,Marco Liuzzo,Giovanni Maio,Marcello Nuvoli +10 more
TL;DR: In this paper, the results of a proof-of-concept study aimed at remotely sensing the volcanic CO2 flux using a Differential Adsorption lidar (DIAL-lidar) were reported on June 2014 on Stromboli volcano.

Time variability of low-temperature fumaroles at Stromboli island (Italy) and its application to volcano monitoring
Paolo Madonia,Emilio Fiordilino +1 more
TL;DR: In this paper, the authors discuss soil temperature data acquired in low-temperature fumaroles at Stromboli volcano in the period 2006-2010 data analysis revealed that short-term anomalies recorded in the thermal signal are potentially useful in predicting state changes of the volcano in particular, sudden changes in fumarole temperatures and their hourly gradients were observed from several days to a few hours prior to fracturing and paroxysmal events, heralded by peculiar waveforms of recorded signals.

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.
