Strong ground motions, which are recorded by accelerometers at temporary or permanent stations during earthquakes, vary depending on magnitude of the recorded event, distance from the earthquake source to station and local site characteristics of the station. These acceleration-time records are input parameters used in different disciplines ranging from earth sciences to earthquake engineering. Strong ground motion networks in the world and Turkey are constantly expanding; thus, both the information on the sources of past earthquakes and the studies on the Earth are increasing in number with the help of different earthquake records. However, since the earthquakes of different magnitudes do not statistically occur with the same frequency, there are deficiencies even in the world's most developed networks. In other words, when the entire potential seismic effects in a region is to be examined, there are no records corresponding to some intensity values. This problem is more evident for the ground motion networks in regions where no dense station distribution is available. Nowadays, ground motion simulation studies are becoming increasingly important all over the world. The main goals of this study are to prepare a simulated earthquake ground motion database on the North Anatolian Fault Zone which is the most active fault zone of Turkey; to investigate the fundamental characteristics of this database, and to present those features by comparing findings obtained from recorded ground motions.

A study on fragility analyses of masonry buildings in Erzincan (Turkey) utilizing simulated and real ground motion records Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Yakut, Ahmet (Elsevier BV; 2017-09-13) Ground motion records are generally required to develop fragility curves which are utilized in seismic loss estimation studies for earthquake prone zones. These records could be 'real', i.e. recorded acceleration time series or 'simulated' records consistent with the regional seismicity and produced using alternative simulation techniques. This study mainly concentrates on development of fragility curves for masonry buildings located in Erzincan (eastern Turkey) using 'simulated' ground motion records and e...
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...
A study on major seismological and fault-site parameters affecting near-fault directivity ground-motion demands for strike-slip faulting for their possible inclusion in seismic design codes Akkar, Sinan; MOGHIMI, SAED; Arıcı, Yalın (2018-01-01) We investigate the role of major seismological (magnitude, pulse period, fault length, seismic activity, orientation of incident seismic wave with respect to fault-strike) and geometrical (fault-site geometry) parameters to understand the variations in ground-motion demands due to near-fault directivity (NFD) effects. To this end, we used a suite of probabilistic strike-slip earthquake scenarios and established the elastic spectral amplitude distributions conditioned on the above investigated parameters. Th...
Identification of morphometric properties of basins located on western part of NAFZ Sarp, Gülcan; Toprak, Vedat; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2012) This study aims to investigate tectonic activity levels and development stages of the tectonic and hydrologic basin areas located on western part of the main trace of the North Anatolian Fault Zone (NAFZ) using quantitative measurement techniques. The basins investigated are Bolu, Yeniçağa, Dörtdivan, Çerkes, Ilgaz and Tosya. The methodology includes application of six morphometric indices (Basin Shape, Hypsometric curve and Hypsometric Integral, Sinuosity of Mountain Fronts, Stream Length Gradient Index, V...
An assessment of the 3 February 2002 Cay (Turkey) earthquake (Mw=6.6): Modeling of ground motions and felt intensity distribution Can, Gizem; Askan Gündoğan, Ayşegül (2021-11-01) Estimation of earthquake ground motions is important for several purposes including seismic design, analysis, risk mitigation and disaster management. For regions with insufficient data, simulations become critical, particularly for earthquake engineering applications requiring full ground motion data. In this study, stochastic finite-fault simulation of the 3 February 2002 Cay event is presented at three available stations within epicentral distances less than 200 km. The simulations are initially validate...
