Case Study and Comparisons Campi Flegrei (CF) caldera is a volcanic district near the city of Naples (Italy). Spectacular ground level variations are reported at CF across the centuries, up to tens of meters. A large unrest episode took place during 1982–1984, accompanied by 1.8 m vertical uplift in Pozzuoli, in the caldera center. A slow deflation phase began in 1985, interrupted by minor uplift episodes of few centimeters, seismic swarms and degassing episodes. Since 2005, CF has been uplifting again. An increase of the ground velocity took place during 2011–2013 showing up to 9 cm/yr in 2012 in the caldera center (Trasatti et al., 2015). I consider the surface deformation obtained by two-orbits datasets of COSMO-SkyMed satellite images (from ASI, the Italian Space Agency), and GPS data from the Neapolitan Volcanoes Continuous GPS (NeVoCGPS) network managed by INGV-Naples related to 2011-2013. The following data inversions have been performed with VSM adopting a sill-like source, according to previous findings at CF (Amoruso et al., 2014; D’Auria et al., 2015; Trasatti et al.,
