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

The authors applied the differential SAR interferometry technique to detect and measure the rise of a basal anticline beneath the urban area of Catania (Italy) which originates from outward thrusting above the basal decollement of Etna volcano. This phenomenon, coupled with the already documented active extension of the volcano summit area, demonstrates the occurrence of the active volcanic spreading process
