Abstract

The NGA-West2 project database expands on its predecessor to include worldwide ground motion data recorded from shallow crustal earthquakes in active tectonic regimes post-2000 and a set of small-to-moderate-magnitude earthquakes in California between 1998 and 2011. The database includes 21, 336 (mostly) three-component records from 599 events. The parameter space covered by the database isM 3.0 toM 7.9, closest distance of 0.05 to 1, 533 km, and site time-averaged shear-wave velocity in the top 30 m of V S 30 = 94 m/s to 2, 100 m/s (although data becomes sparse for distances >400 km and V S 30 > 1, 200 m/s or <150 m/s). The database includes uniformly processed time series and response spectral ordinates for 111 periods ranging from 0.01 s to 20 s at 11 damping ratios. Ground motions and metadata for source, path, and site conditions were subject to quality checks by ground motion prediction equation developers and topical working groups.
