Abstract

An approach for the retrieval of long-term deformations from a set of differential interferograms is presented. The method consists in solving simultaneously in a least squares sense all the interferograms to determine the terrain deformations as a chronological sequence. With this approach, the temporal evolution of the subsidence in the neapolitan area of the Phlegrean Fields has been determined for the period 1993-1999
