In this study, stochastic earthquake catalog of the Erzincan region in Turkey is generated based on synthetic ground motions. Monte Carlo simulation method is used to identify the spatial and temporal distribution of events. Ground motion time histories are generated using stochastic simulation methodology. Annual exceedance rate of each ground motion amplitude is calculated through statistical distribution of the complete set of ground motions. The results are compared with classical probabilistic seismic hazard analysis (PSHA). Classical PSHA generally produces larger spectral amplitudes than the proposed study due to wide range of aleatory variability. The effects of near-field forward directivity and detailed site response are also investigated on the results.

Seismic hazard assessment for Cyprus Cagnan, Zehra; TANIRCAN, GÜLÜM (Springer Science and Business Media LLC, 2010-04-01) In the present study, probabilistic seismic hazard assessment was conducted for Cyprus based on several new results: a new comprehensive earthquake catalog, seismic source models based on new research, and new attenuation relationships. Peak ground acceleration distributions obtained for a return period of 475 years for rock conditions indicate high hazard along the southern coastline of Cyprus, where the expected ground motion is between 0.3 and 0.4 g. The rest of the island is characterized by values repr...
Estimation of seismic losses in urban regions within an interdisciplinary framework a case study Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet; Asten, Michael; Karim Zadeh Naghshineh, Shaghayegh (2014-04-30) Abstract – The purpose of the study described in this article was to assess teachers’planning practices at the primary-school level in Turkey. Altogether 210 schools weresurveyed, a questionnaire was distributed to all teachers in these schools, and 1194teachers responded to the questionnaire. The results indicated that the main sourcesof influence on daily and unit plans are teachers’ experience, the national curriculumand the course textbooks. In daily planning, teachers ass...
3D resistivity imaging from an archaeological site in south-western Anatolia, Turkey: a case study Drahor, M. G.; Gokturkler, G.; Berge, M. A.; Kurtulmus, T. Oe.; Tuna Çengel, Nur Nagihan (Wiley, 2007-06-01) A large-scale resistivity imaging survey was performed in the acropolis area of Archaic Cnidos, south-western Turkey. This survey was a part of the geophysical studies conducted between 1999 and 2004. Two-dimensional resistivity data were acquired along a number of parallel lines using a pole-pole array. The data was processed using a 3D inversion algorithm based on a robust technique. We also applied shaded-relief processing to enhance the representation of the images of apparent-resistivity data and inver...
Site-dependent spectra derived from ground motion records in Turkey Kalkan, E; Gulkan, P (SAGE Publications, 2004-11-01) The current spectral shapes in the Turkish Seismic Code (TSC) are based on broadly described geological conditions, ignoring fault distance or magnitude dependencies on spectral ordinates. To address this deficiency, a data set created from a suite of 112 strong ground motion records from 57 earthquakes that occurred between 1976 and 2003 has been used to develop horizontal attenuation relationships for Turkey. This way it is possible to construct hazard-consistent design spectra for any national seismic re...
Ground Motion Prediction Equations for the Vertical Ground Motion Component Based on the NGA-W2 Database Gülerce, Zeynep; Abrahamson, Norman A.; Silva, Walter J. (SAGE Publications, 2017-05-01) Empirical ground motion models for the vertical component from shallow crustal earthquakes in active tectonic regions are derived using the PEER NGA-West2 database. The model is applicable to magnitudes 3.0-8.0, distances of 0-300 km, and spectral periods of 0-10 s. The model input parameters are the same as used by Abrahamson et al. (2014) except that the nonlinear site response and depth to bedrock effects are evaluated but found to be insignificant. Regional differences in large distance attenuation and ...
