000020005 520__ $$2eng$$aThe NGA-Subduction site database, which is currently in development, contains information on site condition and instrument housing for 5520 strong motion stations with recordings that are being used for ground motion model development. The stations are from coastal and inland regions that have recorded subduction zone earthquakes (both interface and intra-slab), mostly in Japan, Taiwan, South America, and the Pacific Northwest and Alaska regions of North America. The principal site parameter is the time-averaged shear wave velocity in the upper 30 m (V S30 ), which we characterize using geophysical measurements where available (approximately 2486 stations to date) and proxy-based relationships otherwise. A secondary site parameter is basin depth, measured both to the 1.0 and 2.5 km/s shear-wave velocity horizons. Here we document the geophysical data sources that have been leveraged in this process and regional considerations regarding the use of proxies to estimate V S30 . We also describe data sources for basin depth and the protocols for assigning V S30 and its uncertainty to strong motion recording sites.
