Abstract
- The synthesis of the Catalogue of Perceptible Earthquakes from 1528 to 1990, which have been obtained and elaborated to be used at the same time as a Data Base in a PC, is presented. Although usually, the periods of time which are used in seismic analysis are limited due to the lack of instrumental information, this Catalogue contain the enough amount of information to allow the extension of that periods of time. As a complement of the Catalogue, examples from the Atlas of Isoseismal Maps of Perceptible Earthquakes which epicenter located in Cuba, was also finished. The last one is fundamental for the characterization of Seismic Attenuation in Cuba in terms of intensity, for Seismic Hazard assessment. The temporal-spatial analysis of the perceptible earthquakes permit us to evaluate the Seismogenic Zones from the Seismotectonic point of view. Furthermore a theoretic-experimental analysis of the Attenuation's Law of Seismic Intensity from Greater Antilles, and the main parameters associated to Seismogenic Zones of Cuba, is showed. These ones were obtained from Isoseismal Maps of perceptible and large earthquakes. The results obtained from the probabilistic and deterministic Seismic Hazard Assessment, for different regions all over the country, have been unified in this paper. From the Seismic Hazard Map resulting, the Seismic Zonation Map with Engineering Purposes was also obtained; the last one was proposed for the New Seismic Cuban Design Code. As a contribution to the characterization of Cuban Seismicity an spatial -- temporary -- energetic analysis of the perceptible aftershocks was made, including their relation with our Seismogenic Zones, obtaining an empirical relationship between the Length of Rupture and the Magnitude values, estimated by Macroseismic Data.
