Abstract : From 10,704 earthquakes listed in the Spanish Catalogue, a 30.8 percent was selected, through a revision and addenda to 'SEISMIC DATA'. With this material, we have studied the density of shocks at the different active quadricles on the area 10W-5 degrees E and 35-44 degrees N, stablishing 22 seismic regions of approximately homogeneous density. A map is prepared, plotting the acceptable epicenters with coordinates computed or deduced from macroseismic determinations. (Author)
