Volcano modelling: control of deep magma dynamics on geophysical network signals

Paolo Papale, INGV Pisa, Italy

Abstract:

Deep magma movements preceding and accompanying volcanic eruptions involve complex physical and chemical processes occurring under extreme P-T conditions. Such processes can not be directly observed, therefore, their investigation combines a number of approaches from the analysis of the volcanic products, laboratory experiments, inversion of the associated signals recorded by the volcano monitoring networks, and numerical modelling. Combining all of the approaches above in a unique frame for understanding volcano dynamics is a frontier in modern volcanology. Here the results of advanced numerical simulations of magma convection and mixing in geometrically complex volcanic systems, and of the associated gravity change, ground displacement, and seismic signals, are illustrated and discussed.
