Physical modeling of volcanic processes and dynamics

Courses

2nd Year

Description including Unit Aims

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.

Intended Learning Outcomes

The goal of this course is to introduce the students to the principles of fluid-dynamics and review the basic physics necessary for understanding the physical models adopted in volcanology. The students will acquire the ability to use existing software and develop new simple models of magma transport and emplacement.
