Engineering characteristics of the near-field strong motions from the 1999 Kocaeli and Düzce Earthquakes in Turkey

  • Haluk Sucuoğlu


The purpose of this paper is to summarize the strong motion data from thenearest stations to the fault ruptures of the August 17, 1999 Kocaeli andNovember 12, 1999 Düzce earthquakes and to document informationthat will be significant for its interpretation. Significant engineeringcharacteristics of the near-field strong motions are discussed, with particularemphasis on the site conditions, rupture directivity effects and transversecomponent orientations relative to the fault. In the course of this study,the most significant strong motion stations and adjacent parts of the faultare visited. All locations are verified using a hand-held GPS receiver. Thusinstrument housing characteristics, preliminary impression on siteconditions, and relatively precise relationship of the stations to the nearestfaulting can be reported.
