Mattia et al. (2004): The Stromboli volcano erupted suddenly on 28 December 2002 after a 17-year period of typically persistent but moderate eruptive activity, followed two days later by a tsunamigenic landslide on its NW flank (Sciara del Fuoco) felt in the coastal areas of southern Italy.
Three continuous GPS stations were deployed near the volcano’s rim sampling at 1 Hz after eruption had started. The authors report on two deformation episodes. A vent migration on 16– 17 February 2003 caused significant displacements at only one site. The second episode on 5 April 2003, a paroxystic explosion from the summit crater was due to shallow magma chambers that give rise to Strombolian explosive activity.
Solaro et al. (2014) present preliminary InSAR results on deformation field on Lipari, Vulcano and Stromboli islands using COSMO-SkyMed (CSK) data both from ascending and descending orbits, generating time series extending from 2008 to 2013. They show that Stromboli is subsiding along the ‘La Sciara del Fuoco’ feature, in correspondence of lava flows up to a few cm/yr. (Solaro et al., 2014).
