dc.description.abstractOn 24 May 2014, a Mw 6.9 earthquake occurred in the west of Gokceada Island, northern Aegean Sea. The earthquake was close to Canakkale, Enez, Tekirdag cities, and damaged 300 buildings in the Marmara Region, NW Turkey. We simulated its broadband (0.1-10 Hz) ground motions including 1D deep and shallow structures soil amplification effects at the 12 strong ground motion stations in the western Marmara Region. The 1D deep velocity structures from the focal layer to the engineering bedrock with an S-wave velocity of 0.78 km/s in different azimuthal directions were tuned by comparing the observed group-velocity dispersion curves of Rayleigh and Love waves from the mainshock with theoretical ones. We also added the shallow parts from previous surveys into the 1D models. Synthetic seismograms on the engineering bedrock were generated using the discrete wave number method with a source model and the 1D deep velocity structures. Then the surface motion was generated considering shallow soil amplification. The synthetic seismograms are generally in good agreement with the observed low and high-frequency parts at most of the stations indicating an appropriateness of the source model and the 1D structural model.

dc.description.sponsorshipThe authors would like to express deep gratitude to the Japan Ministry of Education, Culture, Sport, Science, and Technology (MEXT) for financial support to Ozlem KARAGOZ' PhD education at the Tokyo Institute of Technology, and Japan Science and Technology Agency (JST) and Japan International Cooperation Agency (JICA) for the financial support in conducting the field survey under the SATREPS project MarDiM Earthquake and Tsunami Disaster Mitigation in the Marmara Region and Disaster Education in Turkey''. We would like to thank for AFAD and KOERI-RETMC for available strong motion and regional earthquake database, respectively. Some figures were plotted with the GMT software (Wessel and Smith 1998). The authors also would like to thank Dr. Hussam Eldein Zaineh for his help and gratitude to Prof. Dr. Ali Pinar for providing the details of source mechanism solution of the Gokceada mainshock. We also thank to the anonymous reviewer and Dr. John Douglas, Associate Editor in Chief of the journal, for helpful comments.
