Thèmes de Recherche :
Imagerie des systèmes volcaniques à différentes échelles:
(1) Caractériser le fonctionnement et l’évolution spatio-temporelle des structures volcano-tectoniques, imager les hétérogénéités mécaniques et zones d’instabilités.
(2) Détecter et imager les zones magmatiques et hydrothermales actives à différentes profondeurs, pour mieux quantifier les phénomènes éruptifs.
(3) Contribuer à la construction d’un schéma 4D multi-paramètres et spatio-temporel de ces systèmes.
