********************************* From: Jacopo Taddeucci <taddeucci@xxxxxxx> ********************************* Dear colleagues, as the deadline for abstract submission approaches, we would like to invite your contributions to the sessions VS009: "Models and Products of Mafic Explosive Activity" Mafic magmas can erupt explosively after a broad range of physical processes that, among those already identified, include: surface bursting of buoyant gas bubble slugs, multifarious interaction of magma with external water, overpressurization of cooled magma plugs, annular gas flow, and fast foaming of volatile-saturated melt. However different these processes may appear, they all reflect the fundamental properties specific of mafic magmas, mainly low viscosity and fast internal kinetics. A current challenge to volcanologists is to relate, possibly in a predictive manner, the above physical processes to the highly-variable eruptive styles observed and the products and hazards they emanate. The aim of this session is to bring together scientists with different approaches to the processes that underlie mafic explosive activity. In particular, three fields of research seems to increasingly converge on this topic: a renewed effort on the study of mafic pyroclasts and pyroclastic deposits; multiparametric geophysical, geochemical, and volcanological observation of ongoing activity; and analytical, numerical, and experimental simulation of eruptive processes. All the above (and other) specific aspects of mafic explosive activity will be welcome to this interdisciplinary session, and we specially encourage the submission of presentations showing integration of different approaches. Conveners Jacopo Taddeucci, Istituto Nazionale di Geofisica e Vulcanologia, Seismology and Tectonophysics, Greg Valentine, Los Alamos National Laboratory. Wishing you a pleasant and fruitful meeting in Perugia, Jacopo and Greg. ------------------------------------- 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. ==============================================================
