Dear all,
We draw your attention to this special session of the 2010 Fall AGU Meeting.
V07: Tracking Magma Through the Crust to Eruption
Sponsor: Volcanology, Geochemistry, and Petrology
CoSponsor: Geodesy, Seismology
Conveners: Thora Arnadottir (Inst. of Earth Sciences, Univ. of Iceland), Olgeir Sigmarsson (CNRS, France), Kristin Vogfjord (Icelandic Meteorological Office), Christopher Bean (Univ. College Dublin)
Description:
The 2010 eruption of Eyjafjallajökull (Iceland) demonstrates the importance of begin able to monitor changes in magma volume and pathways in real time. In the case of Eyjafjallajökull, intrusive activity led to a basaltic flank eruption on March 20, which in turn was followed by a second more explosive eruption in the ice covered summit caldera on April 14. Eruptive behavior depends on the vent location, as well as magma volume and composition, which can be difficult to forecast. The correspondence between observed volcanic tremor and eruption activity is clearly complex. The aim of this session is to bring together interdisciplinary studies from volcanoes worldwide to shed light on magma storage, ascent as well as intrusive and eruptive behavior.
Abstract submissions are scheduled to open on 21 July and close on 2 September. Please check the AGU website (http://www.agu.org/meetings/fm10/) for updates.
Best wishes,
Thora Arnadottir, Olgeir Sigmarsson, Kristin Vogfjord and Chris Bean
