Determination of the Site Characteristics from Mictroremor Measurements in Gumushane Campus Area

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. Most important advantage of Nakamura method defined as single station method isn’t required 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) method has been applied to microtremor records taken with CMG-6TD three component broad band velocity seismometers in 6 profiles and 40 points with the aim of determining ground predominant period and magnification parameters of the Gumushane University and its surrounding area located in Northeast of Turkey. Maps of magnification, predominant frequency and ground classification (Z2 and Z3) according to the predominant period are created by derived values.
