TL;DR: In this article, the results of two years of real-time observation of H2O, CO2, and SO2 in volcanic gases from Mount Etna volcano were unambiguously demonstrated that increasing CO2/SO2 ratios can allow detection of pre-eruptive degassing of rising magmas.

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.

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%).

TL;DR: In this article, the first measurements of bromine and iodine emissions from Mount Etna were made using filter packs and contemporaneous ultraviolet spectroscopic SO2 flux measurements, resulting in time-averaged emission rates of 0.7 kt yr−1 and 0.01 kt dc−1 for Br and I, respectively, from April to October 2004, from which they estimate global Br and iodine fluxes of order 13 (range, 3-40) and 1.11 (range 0.04-6.6) kt rc−1.

TL;DR: In this paper, the total volatile flux from Mount Etna volcano has been characterised for the first time, by summing the simultaneously evaluated fluxes of the three main volcanogenic volatiles: H2O, CO2 and SO2.
