Dear list members and colleagues,
We kindly invite you to submit a contribution in our session GMPV30/NH2.2/TS3.5 entitled:
"The mechanics of volcanic and sub-volcanic systems: modelling, experiments and field observations"
Conveners: Olivier Galland, Steffi Burchardt, Galen Gisler, Eoghan Holohan, and Matthieu Kervyn
Volcanic systems evolve through the interaction of numerous processes
governing the ascent, emplacement and eruption of magma. These
highly-dynamic 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 tackle. Understanding the
physics 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 those who address the physical and
temporal development of sub-volcanic and volcanic phenomena by using
field or geophysical observations, theoretical or analytical solutions,,
and experimental or numerical models. This session includes, but is not
restricted to, the following topics:
- Physics of melt segregation in magmatic sources;
- Fluid mechanics of crystal-bearing melts;
- 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;
- Effects of regional-tectonics on intrusions, edifices and volcanic fields;
- Prediction of volcanic vent location and distribution;
- Fragmentation of the magma and the host rock during magmatic and
phreatomagmatic explosions;
- Dynamics of volcanic jets and plumes;
- Depositional processes in turbulent flows
This session is 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.
Invited speakers:
Jacopo Taddeucci (INGV Rome, Italy, to be confirmed)
Nick Schofield (School of Geography, Earth and Environmental Sciences,
University of Birmingham, UK)
Michel de Saint Blanquat (University of Toulouse, France
