Geodetic measurements and numerical models of volcanic unrest at large silicic systems.

I will examine the ground deformation associated to non-eruptive unrests at two volcanic systems: the Laguna del Maule volcanic field (Chile), experiencing high uplift rates since 2007, and the Long Valley caldera (USA), experiencing multiple episodes of surface uplift over the last 40 years. I will present results from analytical and numerical models to interpret these episodes of ground deformation in terms of magmatic processes.
