Description:
A modelling of the observed macroseismic intensity of historical and instrumental
earthquakes in southern Spain is proposed, with the aim of determining the macroseismic parameters for
seismic hazard evaluation in a region in which the characterization of intensity distribution of seismic
events shows different levels of difficulty referable to the complex faults system of the area in study.
The adopted procedure allows an analytical determination of epicenters and principal attenuation
directions of earthquakes with a double level of verification with reference to the maximum shaking area
and structural lineaments of the region, respectively. The analyses, carried out on a suitable number of
events, highlight, therefore, some elements for a preliminary characterization of a seismic zonation on the
basis of the consistency between seismic intensity distribution of earthquakes and corresponding structural
framework.
