******************************************************************* From: Seth Moran <smoran@xxxxxxxx> ******************************************************************* We encourage you to submit an abstract to the following session at the Fall AGU meeting in San Francisco, December 10-14 2007: V27: Tracking Magma Movement and Storage in Basaltic Edifices: From Models to Field Observations Recent data indicate that large volumes of magma in basaltic systems may be injected into an edifice from a shallow reservoir without being easily detected by any geophysical sensors. A fraction of the magma does not erupt, but has large effects on fluid pressures and local stresses inside the edifice. Lack of knowledge of the stored magma volume and movement limits our ability to develop realistic numerical models that can be applied to real basaltic systems. The finding of geophysically invisible intrusions suggests the need for an interdisciplinary approach, using geophysical, geochemical, and geological models and datasets collected on active volcanoes worldwide, to address the problems of magma storage and movement within large edifices. The main goals of this session are 1) to test the ideas suggesting large magma injections in edifices using field data and modeling 2) to help define a new strategy for upgrading monitoring networks on active edifices. Presentations from geological, geophysical and geological modelers as well as field observers will be welcome. Abstract deadline September 6, 2007.
