Vergleich der neuen Erdbebengefährdungskarten der Schweiz, Deutschlands, Österreichs und Frankreichs für die Nationalen Anhänge zum Eurocode 8.

Comparison of the new seismic hazard maps of Switzerland, Germany, Austria and France for the National Annexes to Eurocode 8 The comparison of the new seismic hazard maps for Switzerland, Germany, Austria and France, which were developed for the National Annexes to Eurocode 8, is the subject of this study. The presented common map covers the southern part of Germany together with adjacent areas of the mentioned neighbouring countries. The map is parameterised for peak soil acceleration (PGA), for a mean return period of 475 years, for median values and for a subsoil with a mean shear wave velocity of the uppermost 30 m of 800 m/s. Along the boundary between Germany and its southern neighbours, the contour lines of the independently calculated seismic hazard maps show an astonishingly good overall agreement. Slightly more significant deviations are only observed for areas with lower seismic hazard. This good to very good agreement can be seen as an indication of the resilience and thus realistic assessments. [ABSTRACT FROM AUTHOR]
