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 measures are proposed to analyze the slope instability hazard in a probabilistic manner. Within the contents of this study, the most compatible NSB displacement model with the regional ground motion characteristics is selected and incorporated into the vector-valued probabilistic seismic hazard assessment framework. The NSB displacement hazard curves are constructed for Asarsuyu Region where a large-scaled seismically induced landslide was observed during 1999 Duzce earthquake. The NSB displacement hazard results are compared with the dynamic analysis results that were conducted immediately after the earthquake and measured slope displacements.

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...
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...

Possible worst-case tsunami scenarios around the Marmara Sea from combined earthquake and landslide sources Latcharote, Panon; Suppasri, Anawat; Imamura, Fumihiko; Aytore, Betul; Yalçıner, Ahmet Cevdet (2016-12-01) This study evaluates tsunami hazards in the Marmara Sea from possible worst-case tsunami scenarios that are from submarine earthquakes and landslides. In terms of fault-generated tsunamis, seismic ruptures can propagate along the North Anatolian Fault (NAF), which has produced historical tsunamis in the Marmara Sea. Based on the past studies, which consider fault-generated tsunamis and landslide-generated tsunamis individually, future scenarios are expected to generate tsunamis, and submarine landslides cou...
Estimation of earthquake damage probabilities for reinforced concrete buildings Yücemen, Mehmet Semih (2003-05-13) Due to uncertainties involved both in the occurrence of earthquakes and in structural response, earthquake damage prediction has to be treated in a probabilistic manner. In this study two statistical methods are presented for the prediction of potential seismic damage to low and mid-rise reinforced concrete buildings in Turkey. These methods are based on the utilization of damage probability matrices and reliability theory. The damage data compiled during recent earthquakes that occurred in Turkey are used ...
