Under such assumption the resulting ground motion prediction equations are likely to have a region-biased median and a large aleatory-variability. With the availability of high quality strong motion datasets such as RESORCE, and advanced Non-linear Mixed Effects Regression algorithms, we could quantify regional variations in ground motion for Europe and Middle-East in a partially non-ergodic region-specific GMPE. In conjunction with the region-specific GMPE, we propose a refinement to the existing partially ergodic sitespecific PSHA methodology to scale seamlessly its applicability at regional level. We apply these methods to perform a partially ergodic site-specific PSHA using OpenQuake for 225 sites in Europe – Middle East. We then quantify the change in estimated hazard as result of shifting from ergodic to partially ergodic PSHA using hazard curves and hazard disaggregation. Region-specific PSHA (225 stations) show changes as large as 25% compared to ergodic computations. Site-specific PSHA performed on 80 stations with more than 5 records predicts even larger changes (more than 50% in some cases).
