Anticline growing beneath the urban area of Catania (Italy) measured by SAR interferometry

A differential SAR interferometry technique to detect and measure the rise of a basal anticline beneath the urban area of Catania (Italy) was applied. The DIFSAR technique was capable of detecting long term phenomena occurring in volcanic areas. Long-term interferograms, both from ascending and descending orbits, were also generated, which pointed towards the presence of two small-amplitude features, which were almost invisible in the short-term ascending data.
