Laboratory volcano geodesy
Volcanic activity is commonly associated with volcano deformation, either inflation or deflation, related to magma movement in the sub-surface. These surface deformation are monitored by GPS and Interferometry Radar, and subsequently inverted using geodetic models to constrain the shapes and parameters of active magmatic conduits.
The results of these models, however, cannot be tested as the magmatic conduits are hidden, and the modelling errors due to. e.g. volcano topography, heterogeneities in the crust, monitoring setup, etc cannot be quantified.
At UiO, in the framework of Håvard Bertelsen's PhD project, we have designed a state-of-the-art laboratory apparatus that:
(1) Simulates magma emplacement,
(2) Monitors associated surface deformation, and
(3) Computes the 3D shape of the magma conduits. The aim of this project is to build on this apparatus to test - for the first time - the robustness of geodetic models commonly used to analyse volcano deformation.
The Master student will have the possibility to evolve in a large group of PhD students and postdocs.
The learning outcomes of the students are numerous: sub-volcanic systems, laboratory modelling, data analysis, data inversion, communication and team work.
