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.Abstract:
[1] The Total Volatile (TV) 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. SO2 flux was determined by routine DOAS traverse measurements, while H2O and CO2 were evaluated by scaling MultiGAS-sensed H2O/SO2 and CO2/SO2 plume ratios to the UV-sensed SO2 flux. The time-averaged TV flux from Etna is evaluated at ∼21,000 t·day−1, with a large fraction accounted for by H2O (∼13,000 t·day−1). H2O dominates (≥70%) the volatile budget during syn-eruptive degassing, while CO2 and H2O contribute equally to the TV flux during passive degassing. The CO2 flux was observed to be particularly high prior to the 2006 eruption, suggesting that this parameter is a good candidate for eruption prediction at basaltic volcanoes.read more

Deep Carbon Emissions from Volcanoes
TL;DR: The role of CO2 degassing from the Earth is clearly fundamental to the stability of the climate, and therefore to life on Earth as discussed by the authors, but the uncertainty in our knowledge of this critical input into the geological carbon cycle led Berner and Lagasa (1989) to state that it is the most vexing problem facing us in understanding that cycle.

TL;DR: In this article, a review of different techniques to derive volcanic SO 2 fluxes using satellite measurements of plumes of SO 2 and investigate the temporal evolution of the total emissions from three very different volcanic events in 2011: Puyehue-Cordon Caulle (Chile), Nyamulagira (DR Congo) and Nabro (Eritrea).

Insights into magma and fluid transfer at Mount Etna by a multiparametric approach: A model of the events leading to the 2011 eruptive cycle

TL;DR: In this article, a multiparametric approach, consisting of comparing volcanological, geophysical, and geochemical data, was applied to explore the volcano's dynamics during 2009-2011, and the inversion of ground deformation GPS data and the locations of the tremor sources were used to constrain both the area and the depth range of magma degassing, allowing reconstructing the intermediate and shallow storage zones feeding the 2011 cyclic fountaining NSEC activity.

TL;DR: In this paper, the first quantitative assessment of the geochemical cycling of volcanogenic elements, from their atmospheric release to their deposition back to the ground, was reported, with an aerosol mass flux ranging from 3000 to 8000 t/a−1.

Volatiles in subduction zone magmas : concentration and fluxes based on melt inclusion and volcanic gas data
TL;DR: In this paper, the fluxes of volatiles subducted back into the mantle along subduction zones and returned from the mantle to the surface reservoir via magmatism suggests that there is an approximate balance for structurally bound H2O and Cl.

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.
