Summary

Local seismic velocity data that influence long-period ground shaking were considered for four urban basin regions in the western United States. Depth to shear wave velocities of 2.5 km/s (Z2.5) and 1.0 km/s (Z1.0) used in the NGA-West2 ground-motion models to account for basin amplification are available here.
