Abstract

The cross-bordering earthquake hazard mapfor three Central European countries, the CzechRepublic, Poland and Slovakia (CZ-PL-SK) in thesense of the Global Seismic Hazard AssessmentProgram (GSHAP) was elaborated both in terms ofmacroseismic intensities and in terms of peak groundaccelerations (PGA). A new earthquake parametriccatalogue for CZ-PL-SK (Schenková et al., 1999)allows the source regions to be delineated withrespect to tectonic structures. Regions for Austriaand Germany were taken from the D-A-CH area withsome modifications in the border zone with the CzechRepublic and Poland. Regions of other surroundingcountries were defined with respect to nationalearthquake catalogues and geologico-geophysical dataof Central European countries. For each sourceregion earthquake data were normalised to obtain areliable annual recurrence graph and the maximumexpected earthquakes. Attenuation laws were definedto allow more advanced earthquake hazard maps to becalculated by the standard probabilistic McGuire's(1976) approach. The obtained GSHAP hazard maps forthe CZ-PL-SK area were calculated for the returnperiod of 475 years. Besides a comparison with thehazard values for the D-A-CH area (Grünthal etal., 1995, 1996; Grünthal, 1997), the map wasalso compared with the effective ground accelerationmap for Austria (Lenhardt, 1996) and in both cases avery good coincidence was found.
