Description :
This paper presents the results of a continuous monitoring of the surface displacements following the April 6th 2009 L’Aquila earthquake. The AA. considered 3-dimensional displacements measured via Robotized Total Station (RTS) installed the April 24th 2009 in the area of Paganica village. The monitoring system was set up in order to reveal potential post-seismic displacements that could cause further damages to the water pipeline. The RTS ran continuously for about one year, with sampling rates varying from 2 to 4 hours, and measured displacements at selected point targets. The revealed surface displacements are in agreement with the results of a DInSAR time series analysis relevant to satellite SAR data acquired over the same area and time period. The results suggest that L’Aquila earthquake post-seismic displacements were dominated by the fault afterslip and/or fault creep, while poroelastic and viscoelastic processes had negligible effects. - (NF)
