Regionalization of seismic hazard in Greece based on seismic sources

ABSTRACT

A seismic-probabilistic approach to the seismic hazard assessment of Greece is presented. For this reason, a recent seismotectonic model for shallow and intermediate depth earthquake sources, based on historial as well as on instrumental data, was used. Different attenuation formulae were proposed for the macroseismic intensity and the strong ground motion parameters for the shallow and the intermediate focal deph shocks. Finally, seismic hazard maps for the area of Greece were compiled utilizing the entire range of recurrence curves. These maps depcit areas of equal seismic hazard and for every area the analytical of the type SI=f (Tm), where SI is a seismic intensity parameter and Tm is the mean return period, were determined (AU)
