Physical modeling of volcanic processes and dynamics

Elements of transport theory (mass, momentum and energy balance). Gas solubility in volcanic melts, exsolution, crystallization. Rheological models (density, viscosity, Newtonian and non-Newtonian rheology, the effect of bubbles and crystals, Bingham fluids). Heat transfer (conduction, convection, radiation). Magma chamber and magma flow in conduits. Sill and dikes. Explosive and effusive eruptions. Convective and collapsing volcanic columns. Modeling lava flows, lahars, convective and collapsing volcanic columns, ash dispersal and pyroclastic flows. Use of deterministic and probabilistic models for estimating the impact of volcanic eruptions and their hazard.

Magmatology

Processes of genesis and differentiation of magmas. Physical and chemical behaviour of magmas and their constituents at variable pressure and high temperature.
