Earthquake-induced slope instability is considered as one of the most important effects of ground shaking, especially in the near fault regions. Simplified tools like Newmark’s Sliding Block (NSB) analogy are widely used to represent the slope stability during ground shaking since the outcome of this analogy is quantitative, larger NSB displacement values indicate higher seismic slope instability risk. Recently, empirical predictive models for NSB displacement were proposed by Saygili and Rathje (2008). Saygili and Rathje (2008) model is incorporated in the vector-valued probabilistic seismic hazard assessment framework by modifying the hazard code, HAZ39. NSB displacement hazard curves are presented for selected locations around the North Anatolian Fault (NAF) system and the effects of rupture distance, site conditions, yield accelerations and seismic source model parameters are evaluated. Preliminary results presented here will be helpful for the assessment of the shortcomings of the method and provide a solid background for future attempts of developing regional NSB displacement hazard maps.
