Dear all,

We draw your attention to this special session of the 2010 Fall AGU  

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  

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.  For more information visit the AGU website (http:// 

Best wishes,
Thora Arnadottir, Olgeir Sigmarsson, Kristin Vogfjord and Chris Bean
