Graizer-Kalkan (2015) ground motion prediction equation (GMPE) is designed to predict peak-ground acceleration and 5% damped pseudo-spectral acceleration response ordinates for shallow-crustal continental earthquakes to be used in earthquake-engineering applications including probabilistic and deterministic seismic hazard analyses. The GK15 can be used for earthquakes with moment magnitudes 5.0–8.0, distances 0–250 km, average shear-wave velocities 200–1,300 m/s, and spectral periods 0.01–5 s. The GK15 GMPE is coded as a MatLAB function (titled “GK15.m”) in the zip file. An example MatLAB code (“demo.m”) to generate a 5% damped pseudo-spectral acceleration response spectrum for a given hazard condition is also provided. The user can change the input parameters to construct a site-specific response spectrum considering different hazard conditions.
