****************************** From: Jacopo Taddeucci <taddeucci@xxxxxxx> ****************************** Dear Colleagues, this is to remind you that next Monday is the deadline for the submission of abstract to the EGU meeting. In particular we draw your attention to the session GMPV7 "Explosive activity at basaltic Volcanoes" Basaltic explosive activity differs from its more felsic counterpart for several, specific aspects. From a physico-chemical point of view, for instance, an extended range of ductile deformation and faster kinematics of magma open the way to peculiar explosive processes, such as surface bursting of buoyant gas slugs, annular gas flow, simultaneous effusive and explosive activity, and multifarious interaction of magma with external water. From an observational and monitoring point of view, basaltic explosive activity is relatively accessible, and an important challenge for the future is how multiparametric records from well-observed basaltic explosions may provide a basis for volcanic explosion theories that apply also to less accessible eruptions. Finally, from an hazard-related point of view, specific hazards are associated with low- intensity basaltic activity, with harmful events like the fallout of ballistic ejecta, paroxysmal explosions, and violent magma-water interaction that often, and unexpectedly, punctuate relatively harmless and prolonged low-level Strombolian and lava flow activity. Here we propose an interdisciplinary session to cover the above (and possibly other) aspects proper of explosive activity at basaltic volcanoes, with particular emphasis to works that integrate different field, experimental, and analytical approaches as well as novel technologies. best wishes for the beginning of 2007, Jacopo Taddeucci & Oliver Spieler ----------------------------------------------- Jacopo Taddeucci Istituto Nazionale di Geofisica e Vulcanologia Dept. of Seismology and Tectonophysics HP-HT Lab. of Experimental Volcanology and Geophysics Via di Vigna Murata 605, 00143, Roma, Italy Tel. +39-06-51-860-502, Fax. +39-06-51-860-507 http://www.ingv.it/%7eroma/profilo/fondazione/sezioni/romauno/LabHP- HT/index.html http://web.genie.it/utenti/j/j.taddeucci/index.html ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
