On 11 May 2011 an earthquake of magnitude 5.2 ( M w) hit the Murcia region of Spain causing significant damage to buildings in the town of Lorca. Accelerograms were recorded by stations of the Instituto Geográfico Nacional, and high-amplitude ground motions were observed at the Lorca station, with a peak ground acceleration (PGA) of 0.37 g. The contribution of a near-field component of ground motion is shown in time histories and in elastic response spectra. Features of near-field ground motions such as directivity could have significantly enhanced the ground shaking caused by this event. Local amplification effects in Lorca were investigated by the H/V spectral ratio technique and an array method. Information obtained from the geophysical field survey allowed the definition of representative soil columns and site classifications according to Eurocode 8. Modeling of site response is conducted for an example location. The aftershocks recorded at different sites confirm the soil amplification at these locations.

“…No obstante, la somera profundidad de la superficie de ruptura y su proximidad al núcleo urbano de Lorca condicionaron las características de la serie sísmica. Asimismo, efectos adicionales de directividad pudieron dar lugar a este carácter impulsivo de corta duración (Susagna et al, 2012;Alguacil et al, 2014).

have once again revealed the inadequate performance of many existing structures under the seismic action. Furthermore, in low-to-moderate seismicity regions, as the Iberian Peninsula, the relatively low frequency of seismic phenomena and the short memory of the population have produced a decrease in the social and institutional perception of the seismic threat.

The seismic records are in general valuable information, especially in cases where damage in buildings has occurred. The main purpose of the present document is to describe the principal results of the analysis of features of ground motions due to the main three earthquakes that occurred in Spain on May 11, 2011. In this day the major earthquake had a magnitude of 5.1 Mw. This event triggered different levels of damage in numerous buildings in the city of Lorca located in southern Spain. Unfortunately, 9 persons died due mainly to the collapse of non-structural elements.We describe in the present paper the application of the software Seismograms Analyzer-e (SA-e) to perform the processing and the analysis of the seismic records obtained in five stations during the main three earthquakes on May 11 (the largest earthquake of magnitude 5.1 Mw, the precursor of magnitude 4.5 Mw, and the aftershock of magnitude 3.9 Mw). We also highlight the significant similitudes between the seismograms generated in the LOR station during these three earthquakes. Additionally, we determined the
