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 evaluate the compatibility of candidate NSB displacement prediction models for the probabilistic seismic hazard assessment (PSHA) applications in Turkey using a comprehensive dataset of ground motions recorded during the earthquakes occurred in Turkey. Then, application of the most suitable NSB displacement prediction model in the vector-valued PSHA framework is demonstrated using the seismic source characterization models developed for Bolu-Gerede Region (in northwest Turkey). The results are presented in terms of the NSB displacement hazard curves and the hazard curves are evaluated for the influence of parameter selection (site conditions, yield acceleration, distance to the fault plane, and other seismic source model parameters) on the final hazard output.

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 of Seismically Induced Landslide for Bakacak-Duzce Region
Balal, Onur; Gülerce, Zeynep (2014-09-19)
Earthquake induced slope instability is considered as one of the major sources of the earthquake hazards, especially in the near fault regions. Simplified tools as Newmark's Sliding Block (NSB) analogy are commonly 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 NSB displacement prediction models based on single or multiple ground motion intensity ...

An Interdisciplinary Approach for Regional Seismic Damage Estimation
Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Karim Zadeh Naghshineh, Shaghayegh; Yakut, Ahmet (2017-01-09)
In order to mitigate seismic risk in urban regions, the first task is to identify potential seismic losses in future earthquakes. Seismic loss estimation is an interdisciplinary framework including a wide range of contributions from geophysical and earthquake engineers, physical and economic planners to insurance companies. In this study, a moderate size city in Turkey, namely Erzincan, is modeled completely from geophysical attributes to the built environment. Erzincan city is on the eastern part of the No...
Modelling the variability in seismically induced slope displacements due to ground motion selection
Özmen, Burak Oka; Gülerce, Zeynep; Department of Civil Engineering (2019)
Assessing the earthquake performance of a slope and estimating the seismically-induced slope displacements is one of the most complicated tasks in geotechnical earthquake engineering. The source of the complication includes: i) defining the soil properties and their variability within the limits of the available geological/geotechnical information, and ii) executing a proper ground motion selection and scaling procedure for the dynamic numerical analysis, which are generally limited in number for most of th...
