Compétences

Eruptive dynamics of explosive volcanoes in a context of increasing urbanization exposed to volcanic hazards. Reduction of volcanic risks by improving seismic monitoring methods. (i) Structure of volcanoes: Location of magmatic reservoirs and internal structure of the edifice by seismic imaging methods (volume waves, ambient noise); (ii) Transfers of magmatic fluids to the surface: Localization of seismogenic zones and temporal monitoring of seismicity migration using dense networks of sensors; (iii) Precursors of eruptions: Detection and automatic classification of seismic-volcanic signals by method of maching learning.
