| Résumé | (disponible en anglais seulement)
We present a ground deformation map for a large portion of the Po Plain messinian to quaternary sedimentary basin near the City of Bologna, Italy. We acquired
and processed fifty nine ascending and thirty eight descending Radarsat-2 images (beam S3) spanning 2008-2013 period and performed the Multidimensional Small Baseline Subset (MSBAS) analysis, which combines ascending and descending data into a single
two dimensional productLvertical and horizontal (east-west) time series of ground deformation for the overlapping area of ascending and descending passes. In the resolved region, we observe subsidence with the rates up to 2 cm/year and minor
horizontal motion. The time series of deformation revealed nearly constant rate of subsidence moderately affected by atmospheric and decorrelation noise. Causes of subsidence were identified in previous studies as related to groundwater withdrawal
for agricultural and industrial purposes. We also produced co-seismic deformation map of the 2012 Emilia earthquake sequence but it is of moderate precision due to severe decorrelation. |
