24 GNGTS 2015 S essione 2.1 sediment. Along the entire Apennines front, it is possible to observe a relative (with respect to the Po Plain) uplift pattern. Moreover, comparing the space distribution of positive values (Fig. 1) with the main tectonic features represented by some buried growing anticlines (not shown in the text for reasons of space), we observe a rough correspondence: positive (uplift) mean ground velocity are located in correspondence of the culminations of the anticlines, in particular along the Mirandola anticline, located below the MO04 GPS station. This could be the result of two phenomena: the sediment compaction, that is higher where the sediment is thicker, and the tectonic growth of the buried active anticlines. Fig. 1 – ENVISAT-ASAR descending mean velocity map along with two examples of displacement time series (1992- 2010), at the top and bottom of the figure. The measurements are in line of sight (LoS): positive values (blue colours) are approaching to the sensor; vice versa for negative ones (red colours). Red stars indicate the main (Mw ≥ 5.0) seismic events; magnitudes are expressed as Mw. Black triangles represents the CGPS.
