| Abstract | We used an expanded PEER NGA-West2 database to develop a new ground motion prediction equation (GMPE) for the average (RotD50) horizontal components of PGA, PGV, and 5%-damped pseudo-absolute acceleration response spectra at 21 periods ranging from 0.01 to 10 s. In addition to those terms included in our now superseded 2008 GMPE, we include a more-detailed hanging-wall model, scaling with hypocentral depth and fault dip, regionally independent geometric attenuation, regionally dependent anelastic attenuation and site conditions, and magnitudedependent aleatory variability. The NGA-West2 database provides better constraints on both magnitude-scaling and distance-attenuation of small-magnitude earthquakes and anelastic attenuation at large distances, where our 2008 GMPE was known to be biased. We consider our new GMPE to be valid for estimating ground motions from worldwide shallow continental earthquakes in active tectonic regions for magnitudes ranging from 3.3 to 7.5–8.5, depending on source mechanism, and rupture distances ranging from 0–300 km. |
