The NGA-West2 project is a large multidisciplinary, multi-year research program on the Next Generation Attenuation (NGA) models for shallow crustal earthquakes in active tectonic regions. has been coordinated by Pacific Earthquake Engineering Research Center (PEER), with extensive technical interactions among many individuals and organizations. addresses several key issues ground-motion seismic hazard, including updating NGA database magnitude range of 3.0–7.9; prediction equations (GMPEs) “average” horizontal component; scaling response spectra damping values other than 5%; quantifying effects directivity directionality ground motion; resolving discrepancies between National Hazards Reduction Program (NEHRP) site amplification factors; analysis epistemic uncertainty GMPEs; developing GMPEs vertical motion. This paper presents an overview its subprojects.
