We combine the potentiality of COMSOL with Monte Carlo optimization procedures, referred to as Simulated Annealing and Genetic Algorithm, in order to analyze and interpret ground deformation measured in active volcanic areas. Through MATLAB® subroutines, we use FE (Finite Element) models that include complexities like topography, vertical and lateral heterogeneities and time-dependent material properties. Preliminary results of an application to a real case show that our approach may help to better represent volcanic processes and lead to a more accurate interpretation and understanding of surface deformation in active volcanic areas.
