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;
- 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.
