Monitoring of an Ancient Landslide Phenomenon by GBSAR Technique in the Maierato Town (Calabria, Italy)

The work deals the monitoring of a single ancient landslide detected in the Vonace area, southwards of Maierato (Calabria, Italy). A 18-hour-measurement campaign has been carried out using the Ground-based Synthetic Aperture Radar (GBSAR) interferometry technique carried between March, 25th and 26th. Displacement maps have been geolocated and overlaid to a Digital Elevation Model of the scene. It has been observed that the Vonace area is almost stable except two portions located at the foot of the ancient landslide and at the centre of the town, respectively. In both cases, a maximum displacement of about 0.5 mm has been measured. A further campaign is needed to confirm this displacement.
