  Seismic crisis occurred in Lorca (Murcia) on 11th May 2011 originated an
important number of accelerograms recorded in the IGN stations. The analysis of
uniformly computed parameters has produced interesting results for Earthquake
Engineering, in particular those recorded in Lorca. Strong ground motion has
been specially observed in the horizontal component perpendicular to the Alhama
de Murcia fault, at the origin of the earthquake. Values of PGA= 0,37g and CAV=
0.27g*s seems to be compensated by a short duration of the motion producing a
macroseismic Intensity not greater than VII in Lorca. The contribution of near
field component of ground motion due to the rupture propagation to and under
the Lorca town was shown on acceleration, velocity and displacement time series
and also on elastic response spectra.
