Özet

The North Anatolian Fault System (NAFS) has a complex geometry and bifurcates into several branches in the eastern Marmara region. The scientific studies conducted in the area have led to numerous fault and fault segmentation interpretations. This study covers detailed lineament extraction from ASTER images and segmentation delineation by using an extensive literature review on a regional scale and focuses on the continental branches of the NAFS in the eastern Marmara region with their known off-shore extensions. A seismic source model with segmentation, fault length, width and slip rate information was prepared as a newly developed line source model for seismic hazard assessment. A probabilistic seismic hazard assessment for the Duzce city center was performed with segment-source-scenario relations and historical seismicity identification for each defined seismic line source in order to check the applicability of this model.
