Geochemical precursors of the activity of an open‐conduit volcano: The Stromboli 2002–2003 eruptive events

Marked increases of CO2, H2 and He dissolved in thermal waters and changes in the dissolved carbon isotopic composition, were observed at Stromboli before the 28 December 2002 eruption and before a violent explosive paroxysm occurred on 5 April 2003. High anomalous CO2 flux values were recorded at t... View More
