dc:description: The results of a new generation of probabilistic seismic hazard assessment (PSHA) for Germany are presented in this report. It summarizes the 2007 PSHA ver-sion. The parameterization of the PSHA in this study is in terms of spectral response accelerations and peak ground accelerations (PGA). With respect to the former it presents a novelty for Germany, while the latter replaces PGA maps of the 1997 PSHA version. This study is the first to systematically consider aleatoric variability and epis-temic uncertainty in the PSHA for a countrywide approach. To account for the epis-temic uncertainty in the seismic source zone model a set of seven models was devel-oped. Two of these source zone models rely basically on the large scale tectonic ar-chitecture and the tectonic regime. The other models, representing small scale seis-mic source zones, consider additionally the observed seismic activity and implica-tions on neotectonic active faults. For each source zone of each model its specific parameters were introduced. The epistemic uncertainties in these parameters are handled in a source specific logic tree. Its first level of branches contains a set of ground motion prediction equations considering the tectonic regime in each source zone. Based on an updated earthquake catalogue for Central Europe in terms of moment-magnitudes, covering the period 1000 AD-2004, sets of magnitude recurrence parameters (nue-beta - pairs and mmax) were developed. To consider the uncertainties in nue and beta we introduce a novel approach resulting in three - nue-beta pairs with their relative weights. For quantifying the maximum expected magnitudes in each source zone we apply the Bayesian based EPRI-approach resulting in a probability density function of mmax. We present the PSHA results in terms of maps of spectral accelerations for mean return periods of 100, 500, 1000, and 2500 years, required in the DIN 19700:2004-07. The hazard calculations were performed for the frequency range of 0.5-50 Hz. This enables the construction of uniform hazard spectra (UHS) for each point within the study area. PGA maps were computed to perform the anchoring of design spectra for a direct comparison with the UHS. We developed an interactive internet based feature where not only the hazard maps in different parameterization and hazard levels can be visualized, but also the UHS for each point within Germany (according to inserted geographical coordi-nates), or for each locality as well for the mentioned four hazard levels. The specifica-tion of the type of geological soil conditions is either automatically provided by the system or can be chosen. According to the knowledge of the authors such a functio-nality for providing UHS is a worldwide novelty.
