Determination of the amplitude values with Nakamura (H/V) method and standard spectral ratio (Ssr) method at Ktu Campus

Abstract

Microtremor method used for engineering seismology is very important for determining of dynamic ground parameters and its variations. Method based on frequency of horizontal and vertical component microtremor records provides to quick and economical estimation of dynamic ground parameters. In this study, Nakamura (H/V) method and Standard Spectral Ratio (SSR) method have been applied to microtremor records taken with CMG-6TD three component broad band velocity seismometers in six profile with the aim of determining ground amplification of Karadeniz Technical University Campus area. The amplification maps of the study area are generated to the results of Nakamura (H/V) method and Standard Spectral Ratio (SSR) method and the results have been compared.
