| dc.description.abstract | Campi Flegrei caldera (Italy) was affected by a new unrest phase during 2011-13. We exploit two COSMO-SkyMed datasets to map the deformation field, obtaining displacement rates reaching 9 cm/yr in 2012 in the caldera center. The resulting dataset is fitted in a geophysical inversion framework using finite element forward models to account for the 3D heterogeneous medium. The best-fit model is a North dipping mixed-mode dislocation source lying at ~5 km depth. The driving mechanism is ascribable to magma input into the source of the large 1982-84 unrest (since similar source characteristics were inferred) that generates initial inflation followed by additional shear slip accompanying the extension of crack tips. The history and the current state of the system indicate that Campi Flegrei is able to erupt again, and the advanced techniques adopted provide useful information for short-term forecasting. | en |
