A new ground motion prediction equation (GMPE) based on representation of attenuation function as a series of filters has been developed using expanded NGA database (Graizer and Kalkan 2007). In this GMPE, each filter represents a certain physical phenomenon on seismic radiation (e.g., distance attenuation, magnitude scaling, site-correction, basin effect, etc.). We use moment magnitude (denoted as M w or M) and closest distance to the fault (denoted as Rcl or R) in our model. The predictive power of this GMPE is examined using a comprehensive set of peak ground acceleration (PGA) data (~14,000) compiled from 245 worldwide shallow crustal events. Comparison of actual data with predictions demonstrates a very good match up to 100 km for a range of magnitudes 4.2 ≤ Mw ≤ 7.9. In order to model a faster attenuation of ground motion data beyond 100 km, two estimator coefficients are updated and a new filter is implemented. The resultant GMPE GK-09 produces good match to recorded global data in both near- and far-field up to 500 km.
