NGA-West3 Database and Tools

This page contains links to the tools available to interact with the NGA-West3 ground motion data. You can download unscaled motions, or select and scale motions to match a target response spectrum.

Download Unscaled Ground Motion Records

Select ground motion records based on magnitude, distance, and V_S30 along with more advanced filter options, and download unscaled records.

Ground Motion Selection and Scaling

Specify one or more target response spectra, find scaled response spectra that match, and download associated motions.
