This module is mutually exclusive with

SOEE3171Volcanic Processes

This module is not approved as an Elective

Objectives

This module is intended to provide an overview of volcanic processes. Through a combination of lectures, practical classes and private study, students will :
i) become familiar with the various types of volcanic eruptions and their products;
ii) understand the physical controls on eruptive processes and the transport and deposition of eruption products;
iii) be aware of volcano monitoring and hazard assessment techniques, including their potential use and restrictions;
iv) have an understanding of the impact of volcanic activity on climate and
v) be aware of the issues related to communication of scientific results in the context of hazard and risk assessment;
vi) Master the theory of volcanic processes.

Coursework will have a strong emphasis on problem solving, so the student will master specialist techniques for quantitatively analysing geophysical problems. Students will gain discipline specific skills involving the understanding of volcanic sources and modern data processing, and have practical experience in reading volcanic monitoring time series.

Learning outcomes
On completion of this module, students should be able to:
-distinguish various types of volcanic eruptions and their products,
-analyse the scope, strengths and weaknesses of different volcano monitoring techniques
-make use of simple equations to model physical and chemical magmatic processes,
-demonstrate expert knowledge of physical volcanology,
-explain the impact of volcanic activity on climate,
-explain the fundamental rules in communicating scientific results to decision makers and the public in the context of hazard and risk assessment


Syllabus

I- Introduction: distribution and tectonic settings of active volcanoes; volcanic products and landforms; eruption styles; perception of volcanoes as physical systems.
- Magma movement: dikes and diapirs; strain rates and rheology of magma and country rocks.
- Magma storage and initiation of eruptions.
- Near surface processes: magma ascent and gas exsolution.
- Links between magma rise speeds, rheology, gas content and eruption styles.
- Basaltic eruptions - types, associations with subsurface behaviour, repose times and eruption durations.
- Lava flow emplacement: influence of rheology, cooling and eruption rate.
- Plinian eruptions: airfall deposition, formation of pyroclastic flows and surges, associated hazards.
- Volcano monitoring and eruption prediction.
- Volcanoes and climate.

In addition 5 computer exercises to achieve expert knowledge in physical volcanology:
- Conduit flow, bubbles in magma, deformation, density, permeability and viscosity.
