The volcanoes we study Understanding volcanism requires the acquisition of field data: visible and thermal imagery, geophysical campaigns, gas, rock and ash sampling for petrological and geochemical analyses, mapping of deposits and destruction, etc. Our targets depend on the current activity, research themes and our collaborations with French laboratories and observatories, as well as partn...

The volcanology team has numerical simulation tools, some of which were developed in the laboratory: the VolcFlow code for modelling volcanic flows, deformation models and magma transfers using boundary elements and fictitious domains (DefVolc). This activity is partly based on the computing resources of the UCA's mesocentre and the platform for remote sensing. [restabs alignment="osc-tabs-left...

The LMV has a space of 100 m² + storage + control room reserved for experiments on volcanic flows (pyroclastic flows, debris avalanches and resulting tsunamis) and on magma intrusions.

Geophysical study of volcanic structures Contact : Philippe Labazuy Technical Manager: Thierry Souriot The internal structure of volcanoes can be studied using geophysical methods. The LMV has a number of facilities for this purpose. See the description and access details.
