Resumen de la investigación: Estoy interesado en comprender el sistema de migración de magmas y fluidos bajo los volcanes y especialmente el modelado de campos de esfuerzo y procesos controlados por el estado termal de la corteza. Entre ellos, me enfoco en la formación/ruptura de los reservorios de magma, su migración y emplazamiento, el colapso de calderas y el desarrollo de reservorios geotérmicos. Comúnmente, mis estudiantes y yo combinamos métodos de campo, modelado numérico y métodos experimentales de la física de rocas para abordar los problemas volcano-tectónicos.
Proyectos actuales: Fondecyt 11190143 – Mechanical architecture and dynamic evolution of caldera faults.
Este proyecto utiliza datos de deformación de la roca de campo, numéricos y experimentales para obtener información sobre la dinámica de la deformación de la caldera, la evolución de las propiedades físicas de la roca y el emplazamiento del magma.
