Volcanic systems evolve through the interaction of numerous processes governing the emplacement, ascent, and eruption of magma. These dynamic processes operate and interlink on scales of millimetres to kilometres, occur at various timescales and involve complex physics at the interface between fluid and solid mechanics that is challenging to tackle. Its understanding is nonetheless crucial for forecasting the location, style and violence of volcanic eruptions, particularly after prolonged dormancy period, and for providing accurate hazard and risk assessments.
This session aims to bring together those who address the physical and temporal evolution of magmatic systems from storage, activation through ascent to eruption by using field or geophysical observations, theoretical or analytical models, and experimental or numerical methods. We welcome contributions addressing magma dynamics, its relationships to physical and chemical properties, and its bearing on the geochemical, geophysical and petrological observables that we are able to record at the surface.
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.
