Abstract:
The basis of the seismic hazard assessment in different geographical regions with dense-populated areas and strategic objectives (dams, nuclear power plants, etc.) is the study of seismicity of the seismogenic sources which affect these sites. The purpose of this paper is to provide a complete set of information relative to the Vrancea seismic source (in the crust and the intermediate depth domains) that is fundamental for the seismic hazard evaluation at Cernavoda nuclear power plant site. The analysis that we propose has to deal with the following items: (1) geometrical definition of the seismic sources, (2) setting the earthquake catalog associated to each seismic source, (3) estimation of the maximum possible magnitude, (4) estimation of the frequency – magnitude relationship, (5) computation of the distribution function for focal distance, (6) correlation between focal depth and magnitude and (7) attenuation law. We discuss also the implications of the model parameters on the seismic hazard level.
