000019792 520__ $$2eng$$aThe increasing accuracy of 3-D earthquake ground motion simulations and demand for long-period (T>1 s) probabilistic ground motions motivate the investigation of a potential method for incorporating simulated ground motions into the U.S. National Seismic Hazard Model. We present preliminary sensitivity results from an amplification-based approach to incorporating simulated ground motions into PSHA. Computations employ simulated ground motions from the Southern California Earthquake Center (SCEC) CyberShake Study 15.4. We outline a method for computing amplified ground motions and for their incorporation in probabilistic seismic hazard analysis. Empirical amplification factors from the analysis of small- to moderate-magnitude earthquakes are employed to identify CyberShake locations where the earthquake ground motions are well characterized by the ground motion prediction equations. Examining ruptures from a single seismic source from the Uniform California Earthquake Rupture Forecast, version 2, we identify a strong dependence of the amplified ground motions to the reference site and rupture realization. These preliminary results prepare the way for improved ground motion characterization at sites where sedimentary basin and finite-fault effects control the strong ground motions.
