Abstract

Field surveys performed by different research groups after the April 6, 2009 L’Aquila earthquake identified the occurrence of surface faulting along the Paganica normal fault, the causative seismogenic source of the event.The AA. integrated coseismic geodetic data – DInSAR and GPS – with geological observations in order to discriminate what, among the different surface rupture patterns, can be considered as evidence of primary surface faulting. The results indicated that the Mt. Stabiata-Mt. Castellano faults, to the north, and the San Demetrio fault, to the south ,detected ground ruptures, respectively – probably activated solely as sympathetic tectonic structures during the 2009 earthquake. These results highlight the effectiveness of entwining geological and geodetic data to discriminate primary surface faulting from secondary fault ruptures, particularly in cases of moderate magnitude earthquakes, i.e. when modest and rather subtle surface faulting can occur. - (NF)
