GNGTS 2014 - Atti del 33° Convegno Nazionale

112 GNGTS 2014 S essione 1.1 analysis give an accurate quantitative information which can be used to support the geological interpretation of the tectonic and fluid-related processes occurring in the post- seismic phase. • The retrieved interferometric results allow us to well reproduce the post-seismic ground deformation. The latter is recognizable in a small area close to the mainshock epicenters and remains above the measurement noise floor for ~6-7 months after the mainshock occurrence. • The study of the pre-seismic (inter-seismic) phase by means of ERS1/2 andASAR-Envisat data covering the 1992-2010 temporal interval allow to identify an interseismic deformation pattern due to the thrusts related anticline growth below the Po plain sediments • The Emilia seismic sequence represents a very interesting case for the study of the complete seismic cycle because of the geodetic, geological and seismological data availability.

Fig. 3 – Observed (A); modelled (B) and residuals (C) velocity maps relative to the post-seismic ascending dataset. The maps are in line of sight (LoS): positive values (blues colours) are approaching to the sensor; vice versa for negative ones (red colours). In D and E we show the slip distributions obtained respectively from the post seismic and coseismic ground velocity field inversions.
