A ground motion prediction equations (GMPEs) for Turkey was developed by Kalkan and Gulkan (2004) using then available indigenous database constituting 112 strong ground motion records from 57 earthquakes that occurred between 1976 and 2003. This model predicts peak ground acceleration (PGA) and response spectral ordinates at 5% of critical damping in the range of 0.1 to 2.0 s (total of 46 periods) over the full range of magnitudes (M4 to 7.5) and distances (Rjb up to 250 km). This model is for the maximum horizontal component of ground motion.
