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: The 2002-03 Mt Etna flank eruption began on 26 October 2002 and finished on 28 January 2003, after three months of continuous explosive activity and discontinuous lava flow output.

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.

TL;DR: Analysis of magmatic gas during a powerful lava fountain, measured with Fourier transform infrared spectroscopy on Mount Etna, Sicily, reveals a fountain gas having higher CO2/S and S/Cl ratios than other etnean emissions, and which cannot derive from syn-eruptive bulk degassing of Etna basalt.

TL;DR: It is concluded that interaction between the pressure exerted by the subsiding reservoir roof and the physical properties of the subsurface flow path explain the gradual near-exponential decline of both the collapse rate and the intensity of the 180-day-long eruption of the Bárdarbunga volcano.
