Description:
The coseismic superficial deformation at the region of Lorca (Murcia, southeastern Spain) due to the Mw 5.1 earthquake occurred on 11 May 2011 was studied by a multidisciplinary team, integrating information from DInSAR, GPS and numerical modeling techniques. Despite the moderate magnitude of the event, quantitative information was obtained from the interferometric study of a pair of SAR images. Coseismic vertical deformation was differentiated from subsidence related to groundwater extraction at the footwall block through a numerical modeling deformation estimation based on elastic rupture dislocations. On the other hand, horizontal crustal deformation rates obtained from the analysis of a GPS network existent in the area are also coherent with the mechanism calculated for the earthquake.
