Modelling magma ascent and degassing
Dr Mike Burton from INGV (Istituto Nazionale di Geofisica e Vulcanolgia) in Pisa (Italy) will be delivering this Hotstuff Seminar.
Recent advances in techniques for field measurements of volcanic gas geochemistry allow us to quantify at ~1 Hz rates the flux and composition of a multitude of magmatic gases. These new results offer the possibility of constraining models of magmatic ascent and degassing with unprecedented detail, however, this requires multi-phase modelling of magma and gas flow integrated with a multiple gas solubility model. Here I present a new numerical model that addresses this multi-phase / multi-gas problem, and use it to examine the 2007 effusive eruption of Stromboli.
All staff and students welcome.
