******************************* From: Angelo Peccerillo <pecceang@xxxxxxxx> ******************************* Dear colleagues, We would like to draw your attention to the VS010 symposium "Modelling the plumbing system of active volcanoes by integrated petrological, geophysical and fluid inclusion studies" to be held during the IUGG General Assembly in Perugia, Italy, 2-13 July, 2007. Conveners: Angelo Peccerillo, Bob Bodnar, Maria Luce Frezzotti e-mail: pecceang@xxxxxxxx; http://www.unipg.it/~pecceang A description of the session is provided below. Best regards, Angelo Peccerillo On the summer of 1982, the Phlegraean Fields started to undergo soil uplift of up to 5 mm uplift per day, accompanied by an intense shallow swarm-type seismicity, with earthquake clusters of up to 100 shocks per hour. Starting from winter 1992, a large fracture opened at the northern crater rim of Vulcano (Aeolian arc, Southern Tyrrhenian Sea), accompanied by and increase in the fumarolic output and gas temperature reaching magmatic-like values of about 700°. However, in both these cases, no eruption occurred and, after a while, the seismicity, fumaroles and soil uplift returned to normality. Why the Phlegraean Fields and Vulcano (as well as other unresting volcanoes) did not erupt, in spite of presenting many symptoms of being in a pre-eruptive stage? Why, on the other hand, some of the recent Etna eruptions have been communicated by.......mountain guides to volcanologists instead of viceversa? The answer to these questions stands in our poor understanding of how volcanoes work and in the lack of reliable models of their internal structure. In order to improve our understanding of the way active volcanoes behave, different approaches and techniques are necessary in their study. This requires integrated efforts from various specialists, including petrologists, geochemists, geophysicists and structural geologists. The symposium "VS010 Modelling the plumbing system of active volcanoes by integrated petrological, geophysical and fluid inclusion studies" planned for the Perugia 2007 IUGG meeting has the objective of attracting the attention of Earth scientist on the need for integrated petrological-geochemical-geophysical and fluid inclusion approach to modelling the plumbing systems of active volcanoes, as a prerequisite to understand their structure and behaviour, establish better basis for monitoring and for forecasting volcanic eruptions. We welcome contributions dealing with single aspects of the modelling problem of plumbing systems of active volcanoes, and with case studies of multidisciplinary investigations of active systems. We plan to collect the most significant contribution in a IAVCEI Series book. -- Angelo Peccerillo Dipartimento di Scienze della Terra Piazza Università 06100 Perugia, ITALY tel +39 075 5852608 Fax +39 075 5852603 e-mail: pecceang@xxxxxxxx http://www.unipg.it/~pecceang Visit also GNP website: http://www.unipg.it/~diegop/gnp/ ============================================================== 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. ==============================================================
