Title: | Forecasting Etna eruptions by real-time observation of volcanic gas composition | Journal: | Geology | Series/Report no.: | 12 / 35 (2007) | Publisher: | The Geological Society of America | Issue Date: | 2007 | DOI: | 10.1130/G24149A.1 | Keywords: | degassing volatiles |
Subject Classification: | 04. Solid Earth::04.08. Volcanology::04.08.01. Gases | Abstract: | It is generally accepted, but not experimentally proven, that a quantitative prediction of volcanic eruptions is possible from the evaluation of volcanic gas data. By discussing the results of two years of real-time observation of H2O, CO2, and SO2 in volcanic gases from Mount Etna volcano, we unambiguously demonstrate that increasing CO2/SO2 ratios can allow detection of the pre-eruptive degassing of rising magmas. Quantitative modeling by the use of a saturation model allows us to relate the pre-eruptive increases of the CO2/SO2 ratio to the refilling of Etna's shallow conduits with CO2-rich deep-reservoir magmas, leading to pressurization and triggering of eruption. The advent of real-time observations of H2O, CO2, and SO2, combined with well-constrained models of degassing, represents a step forward in eruption forecasting. |
