Dear colleagues,
My co-conveners and myself invite you to submit a contribution to the following session of the next EGU General Assembly (Vienna, April 22 – 27, 2012) symposia. The abstract submission deadline is 17 January 2012.

GMPV4.7: Physics and dynamics of magma ascent, emplacement and eruption
in volcanic systems
Sollicited speaker:
Eleonora Rivalta (University of Hamburg)
Conveners: O. Galland, J. Kavanagh , C. Annen , N. Le Corvec , S.
Burchardt , G. Gisler , E. Holohan , M. Kervyn
Volcanic systems evolve through the interaction of numerous highly
dynamic processes that govern the ascent, emplacement and eruption of
magma. These processes operate and interlink on scales of millimetres to
kilometres, from the Mantle to the Earth’s surface, and involve complex
physics that are challenging to address. Understanding the physical and
temporal development of volcanic systems, whether single edifices or
volcanic fields, is nonetheless crucial for forecasting the location,
style and violence of volcanic eruptions, and for providing accurate
hazard and risk assessments.
This session aims to bring together geoscientists, physicists and
theoreticians who address the physical development of sub-volcanic and
volcanic phenomena by using e.g. experimental, numerical and analytical
modelling, and field-based approaches. This session includes, but is not
restricted to, the following topics:
- Fracture mechanics in rocks related to dyke, sill and cone sheet
emplacement;
- Deformation of both magma and host rock related to pluton and
laccolith emplacement;
- Prediction of volcanic vent location and distribution;
- Effects of regional-tectonics on intrusions, edifices and volcanic fields;
- Fragmentation of the magma and the host rock during magmatic and
phreatomagmatic explosions;
- Dynamics of volcanic jets, plumes and turbulent flows.
This session is fundamentally process-oriented, and it aims to trigger
cross-disciplinary interactions. We therefore strongly encourage
comparisons and validation of modelling results with field and/or
geophysical observations, as this is a crucial step toward fully
unravelling the complex processes beneath, within and upon volcanoes.
