| Abstract | The hybrid empirical method (HEM) of simulating ground motion intensity measures (GMIMs) in a target region uses stochastically simulated GMIMs in the host and target regions to develop adjustment factors that are applied to empirical GMIM predictions in the host region. In this study, the HEM approach was used to develop two new ground-motion prediction equations (GMPEs) for a target region defined as central and eastern North America (CENA), excluding the Gulf Coast region. The method uses five new empirical GMPEs developed by the Pacific Earthquake Engineering Research Center (PEER) for the NGA-West2 project to estimate GMIMs in the host region. The two new CENA GMPEs are derived for peak ground acceleration (PGA) and 5%-damped pseudo-acceleration response-spectral ordinates (PSA) at periods ranging from 0.01 to 10 sec, moment magnitudes (M) ranging from 3.0 to 8.0, and shortest distances to the fault-rupture surface (RRUP) as far as 1000 km from the site, although we caution that the GMPEs are best constrained for RRUP < 300–400 km. The predicted GMIMs are for a reference site defined as CENA hard-rock with VS30 = 3000 m/sec and κ 0 = 0.006 sec, where VS30 is the time-averaged shear-wave velocity in the top 30 m of the site profile and κ0 is the total attenuation of the ground motion as it propagates through the site profile. |
