Space geodetic techniques such as Interferometric Synthetic Aperture Radar (InSAR) and Global Positioning Systems (GPS) have demonstrated useful in mapping the displacement field of large earthquakes (Mw ~6 or higher) but the displacement fields of smaller earthquakes (< Mw 5.5), such as the ones that typically results from the European and African plates collision, are less often analyzed form space geodetic techniques and their characterization, in terms of slip on the fault plane at depth and focal depth location, often challenges seismologic techniques. In this study we present the results of InSAR analysis of the 11 of May 2011 Mw 5.1 Lorca earthquake. We use 4 SAR data acquired from the European C-band Advanced SAR (ASAR) sensor onboard Envisat satellite to map the ~3 cm of surface displacement field produced by the Lorca earthquake (Figure 1). Then, we use a simple elastic dislocation model (as described in [1]) to characterize the fault plane geometry and the fault slip at depth and adjust its parameters to fit the observed deformation. We found that the Lorca earthquake ruptured a ~3 km segment of the Alhama de Murcia Fault, centered at 4.2 km depth and produced ~21 cm reverse slip with ~6 cm left lateral component on a 45° plane striking N65E (Figure 2). We also observed a high level rate (~0.7 cm/month) subsidence in the Guadalentin basin due to water pumping for intensive agriculture. This value is in accordance with those reported by other authors (e.g. [2]), with no significant rate change associated with the earthquake.
