ASSESSMENT OF THE PEAK ACCELERATION, AMPLIFICATION RATIO AND FUNDAMENTAL PERIOD PROPERTIES FOR THE KIRIKKALE PROVINCE SETTLEMENT AREA

Due to its proximity to active fault zones such as Bala, Seyfe, Karakecili, Kirikkale-Sungurlu and Keskin, the province of Kirikkale is classified within the highest earthquake hazard zone in accordance to the Turkish Earthquake Code. In this study; a site-specific site response analysis was performed using equivalent linear method to estimate the local site effects on seismic ground motions and for guidance to the future construction activities. For this purpose, geotechnical and geophysical data compiled from 107 soil exploration borings, 15 seismic refraction and 6 MASW tests were employed. In the analyses, the ground motion record of the 1999 Duzce Earthquake from the Lamont-1061 station was used. The spatial distribution of peak ground acceleration, soil amplification ratio and the fundamental period are presented as maps. The results indicate high ground acceleration and medium-high period values within the study area.
