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. The most important advantage of Nakamura method defined as single station method does not require reference point and it can be applied easily in the area with low seismic density and without base rock. In this study, Nakamura (H/V) spectral ratio method has been applied to microtremor records taken with CMG-6TD three component broad band velocity seismometers at 116 points with the aim of determining ground predominant period and magnification parameters in the study area. Maps of predominant period and H/V ratio of the study area are created by derived values.
