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

Marked increases of CO 2 , H 2 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 CO 2 flux values were recorded ... View More
