Measuring non-linear deformation of the Campi Flegrei caldera (Naples, Italy) using a multi-method insar-geophysical approach

Geodetic monitoring of Campi Flegrei caldera, west of Naples (Italy), has been historically carried out through ground-based networks and integrated at the end of the nineties with space-borne InSAR techniques, exploiting the C-band sensors onboard ERS1-2 and ENVISAT satellites. In the last years C-band monitoring has been complemented by high-resolution X-band (TerraSAR-X) investigations, in order to point out also small deformations which are typical in the area. The uplift event starting in 2011 was strong enough to be detected by both ENVISAT and TerraSAR-X observations and confirmed by classical geodetic techniques. Besides the integration of geodetical and geochemical data with the InSAR results, we also include the outcomes of the InfraRed (IR) thermal camera located at Pisciarelli site, in order to get also a very local information.
