UE Dynamics and volcanic risk



This module will present the magmatic and eruptive processes occurring in volcanoes, the main methods of volcano study and monitoring, as well as the various approaches for estimating volcanic hazard and predicting eruptions. It is broken down into four chapters.

1. The magmatic processes in the magma chamber and conduit (composition, physical properties, flow dynamics) will be presented.

2. As part of the study of eruption dynamics, the different eruption modes of volcanic products (plume, pyroclastic flow, dome, lava flow) will be addressed, along with their physical mechanisms and ways to identify them in the geological record.

3. The most commonly used geophysical monitoring methods (seismology, deformation, study of gas emissions) will be presented by showing their contributions to the prediction of eruptions and knowledge of volcanic processes. The different remote-sensing methods employed in this area (optical, thermal or radar imaging) will be described, while stressing the specificities of these techniques for their applications to volcanology and monitoring. 

4. The various approaches used to assess volcanic hazard will be studied: mapping of eruptive products, reconstitution of the eruptive history, probabilistic and deterministic methods for predicting eruptions.
