The objective of this article is to provide state-of-the-art probabilistic seismic-hazard assessment maps for the East Anatolian fault zone (EAFZ) based on planar seismic-source models and up-to-date ground-motion models. Development of fault-based seismic-source models requires the definition of source geometry in terms of fault length, fault width, fault-plane angles, and segmentation points for each segment of the EAFZ, building rupture systems that consider fault-to-fault ruptures and associating the observed seismicity with defined rupture systems. This complicated task was performed by compiling the seismotectonic characteristics of the EAFZ using available geological information and the instrumental earthquake catalogs of Turkey. Recently published global Next Generation Attenuation (NGA)-West2 groundmotion models (Bozorgnia et al., 2014) and Turkey-adjusted NGA-West1 models (Gülerce et al., 2016) are used in the ground-motion logic tree with equal weights. The results are presented in terms of the seismic-hazard maps for hazard levels in design codes for different spectral periods and for rock-like reference site conditions (VS30 760 and 1100 m=s).

Probabilistic Seismic-Hazard Assessment for East Anatolian Fault Zone Using Planar Fault Source Models
Gülerce, Zeynep; MENEKŞE, Akin; Özacar, Atilla Arda; Kaymakcı, Nuretdin; Çetin, Kemal Önder (2017-10-01)
The objective of this article is to provide state-of-the-art probabilistic seismic-hazard assessment maps for the East Anatolian fault zone (EAFZ) based on planar seismic-source models and up-to-date ground-motion models.

Probabilistic seismic hazard assessment for east anatolian fault zone using planar source models
Menekşe, Akın; Gülerce, Zeynep; Department of Civil Engineering (2015)
The objective of this study is to perform probabilistic seismic hazard assessment (PSHA) using planar seismic source characterization models for East Anatolian Fault Zone (EAFZ) and to update the design ground motions to be used in the region. Development of planar seismic source models requires the definition of source geometry in terms of fault length, fault width, fault plane angles and segmentation points for each segment and associating the observed seismicity with defined fault systems. This complicat...
Probabilistic seismic hazard assessment of Eastern Marmara Region
Gülerce, Zeynep (Springer Science and Business Media LLC, 2013-10-01)
The objective of this study is to evaluate the seismic hazard in Eastern Marmara Region using an improved probabilistic seismic hazard assessment methodology. Two significant improvements over the previous seismic hazard assessment practices are accomplished in this study: advanced seismic source characterization models in terms of source geometry and recurrence relationships are developed, and improved global ground motion models (NGA-W1 models) are employed to represent the ground motion variability. Plan...
Probabilistic seismic hazard assessment of Eastern Marmara and evaluation of Turkish Earthquake Code requirements
Ocak, Recai Soner; Gülerce, Zeynep; Department of Civil Engineering (2011)
The primary objective of this study is to evaluate the seismic hazard in the Eastern Marmara Region using improved seismic source models and enhanced ground motion prediction models by probabilistic approach. Geometry of the fault zones (length, width, dip angle, segmentation points etc.) is determined by the help of available fault maps and traced source lines on the satellite images. State of the art rupture model proposed by USGS Working Group in 2002 is applied to the source system. Composite reoccurren...
Probabilistic models for the initiation of seismic soil liquefaction
Çetin, Kemal Önder; Kiureghian, AD; Seed, RB (2002-01-01)
A Bayesian framework for probabilistic assessment of the initiation of seismic soil liquefaction is described, A database, consisting of post-earthquake field observations of soil performance, in conjunction with in situ "index" test results is used for the development of probabilistically-based seismic soil liquefaction initiation correlations. The proposed stochastic model allows full and consistent representation of all relevant uncertainties. including (a) measurement/estimation errors, (b) model imperf...
