The purpose of this paper is to summarize the strong motion data from the nearest stations to the fault ruptures of the August 17, 1999 Kocaeli and November 12, 1999 Duzce earthquakes and to document information that will be significant for its interpretation. Significant engineering characteristics of the near-field strong motions are discussed, with particular emphasis on the site conditions, rupture directivity effects and transverse component orientations relative to the fault. In the course of this study, the most significant strong motion stations and adjacent parts of the fault are visited. All locations are verified using a hand-held GPS receiver. Thus instrument housing characteristics, preliminary impression on site conditions, and relatively precise relationship of the stations to the nearest faulting can be reported.

Sensitivity Study of Hydrodynamic Parameters During Numerical Simulations of Tsunami Inundation Ozer, Ceren; Yalçıner, Ahmet Cevdet (Springer Science and Business Media LLC, 2011-11-01) This paper describes the analysis of a parameter, "hydrodynamic demand,'' which can be used to represent the potential for tsunami drag force related damage to structures along coastlines. It is derived from the ratio of drag force to hydrostatic force caused by a tsunami on the structure. It varies according to the instantaneous values of the current velocities and flow depths during a tsunami inundation. To examine the effects of a tsunami in the present study, the analyses were performed using the tsunam...
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...
Broadband Ground Motion Simulation Within the City of Düzce (Turkey) and Building Response Simulation Ozmen, Ekin; Karim Zadeh Naghshineh, Shaghayegh; Askan, Aysegul (Springer Science and Business Media LLC, 2020-05-01) In areas with significant seismic activity and insufficient seismic networks, simulated ground motions are required for both seismic hazard and engineering analyses. One important task is evaluating the efficiency of the simulated records in building response estimation. In this study, a hybrid ground motion simulation framework is presented to obtain broadband ground motion time histories of a past major earthquake in Düzce (Turkey). The hybrid ground motion simulation framework presented herein is a combi...
Time domain Gauss-Newton seismic waveform inversion in elastic media Sheen, Dong-Hoon; Tuncay, Kağan; Baag, Chang-Eob; Ortoleva, Peter J. (Oxford University Press (OUP), 2006-12-01) We present a seismic waveform inversion methodology based on the Gauss-Newton method from pre-stack seismic data. The inversion employs a staggered-grid finite difference solution of the 2-D elastic wave equation in the time domain, allowing accurate simulation of all possible waves in elastic media. The partial derivatives for the Gauss-Newton method are obtained from the differential equation of the wave equation in terms of model parameters. The resulting wave equation and virtual sources from the recipr...
Performance Comparison of NAMI DANCE and FLOW-3D((R)) Models in Tsunami Propagation, Inundation and Currents using NTHMP Benchmark Problems Sogut, Deniz Velioglu; Yalçıner, Ahmet Cevdet (Springer Science and Business Media LLC, 2019-07-01) Field observations provide valuable data regarding nearshore tsunami impact, yet only in inundation areas where tsunami waves have already flooded. Therefore, tsunami modeling is essential to understand tsunami behavior and prepare for tsunami inundation. It is necessary that all numerical models used in tsunami emergency planning be subject to benchmark tests for validation and verification. This study focuses on two numerical codes, NAMI DANCE and FLOW-3D((R)), for validation and performance comparison. N...
