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.

Probabilistic seismic hazard assessment for earthquake induced landslides Balal, Onur; Gülerce, Zeynep; Department of Civil Engineering (2013) Earthquake-induced slope instability is one of the major sources of earthquake hazards in near fault regions. Simplified tools, such as Newmark’s Sliding Block (NSB) Analysis are widely used to represent the stability of a slope under earthquake shaking. The outcome of this analogy is the slope displacement where larger displacement values indicate higher seismic slope instability risk. Recent studies in the literature propose empirical models between the slope displacement and single or multiple ground mot...
Probabilistic seismic hazard assessment for sliding displacement of slopes: an application in Turkey Gülerce, Zeynep (2017-07-01) Earthquake-induced slope instability is one of the major sources of earthquake hazards in near fault regions. Simplified tools such as Newmark's sliding block (NSB) analysis are widely used to estimate the sliding displacement of slopes during earthquake shaking. Additionally, empirical models for predicting NSB displacement using single or multiple ground motion intensity measures based on global (e.g. NGA-W1 database, Chiou et al. 2008) or regional datasets are available. The objective of this study is to...

Estimating the Liquefaction Related Geotechnical Hazards in Probabilistic Seismic Hazard Assessment Framework Gülerce, Zeynep (2016-06-26) The objective of this study is to develop a performance-based earthquake engineering (PBEE) framework for the liquefaction-related hazards and estimate the hazard levels for liquefaction-related engineering demand parameters (EDPs) in a probabilistic manner. Two efficient, sufficient, and hazard compatible EDPs: probability of liquefaction (PL) and post-liquefaction settlement (δL) are selected. Seismic demand models that explain the relationship between these EDPs and ground motion IMs are employed in a se...
