    Description: Les collines Albanes désignent un complexe du quaternaire, situé environ 15 km au sud-est de Rome, qui occupe grosso modo un carré délimité par les latitudes 41,6° et 41,9° nord, et les longitudes 12,5° à 12,9° est. Cette zone revet un intèret particulier pour la communauté géophysique en raison de ses caractéristiques particuliéres dues à un volcanisme résiduel.

    Description: The Colli Albani volcanic complex (Rome, Italy) has been dominated by episodic eruptions commencing around 561 ka and ending with the most recent activity of the Albano maar phase (\70 ka). Earthquakes of moderate intensity, gas emissions and significant ground deformations are the recent evidences of a residual activity. Former geodetic data from leveling surveys, GPS stations and InSAR observations tracked ongoing significant uplift of the order of few mm/year near the Colli Albani western flank. Different uplift rates were detected by each technique in different time spans, suggesting also the possibility of sporadic recharge of the hydrothermal system. The renewed high precision leveling data from IGMI survey carried out in 1997/1999 and the last leveling survey carried out in 2006 show that the uplift along the route is currently significant at an average rate of *3 mm/year. Radar interferograms from ALOS satellite show uplift rate of *6 mm/year, southwest of the central sector of the leveling route. We have undertaken a joint inversion of the various geodetic data (vertical rates from leveling surveys, GPS site velocities and InSAR observations acquired by ALOS satellite) using a nonlinear inversion technique to estimate the parameters of a point-pressure source, possibly capable of explaining the ongoing deformation at Colli Albani volcano.
