Sažetak
This manuscript presents the seismic source characterization models that were developed and used for the Western Balkan Region in the framework of Harmonization of Seismic Hazard Maps in the Western Balkan Countries Project (BSHAP) funded by NATO-Science for Peace and Security Program. Relevant knowledge about the geological and seismotectonic structure of Western Balkans and surrounding region was collected and used along with the BSHAP focal mechanism solutions database and the BSHAP earthquake catalogue (Markušić et al., 2016) to delineate alternative seismic source models for different purposes. The super zone model with large zones bounds the regions with similar seismotectonic characteristics and catalogue completeness levels and was used for calculating the magnitude recurrence model parameters (b-value). Alternative models with smaller zones represent the epistemic uncertainty in source geometry, maximum magnitude and style-of-faulting. Developed models are employed in the two-stage (circular and elliptical) smoothing procedure. Sets of sensitivity analyses are performed to evaluate the combined effect of source zone delineation, recurrence parameter selection, and the method of spatial smoothing on the hazard outcome. The seismic source models and the logic- tree presented here are implemented in the probabilistic seismic hazard assessment for the seismic hazard maps of the Western Balkan Region (Kuka et al., 2017).
