NGA Subduction Database Preliminary Ground Motion Suite (Public Release) 
R210510 (May 2021)

A preliminary set of 500 ground-motion records has been pre-selected for public use.

10 May 2021 Update: (1) All records have been baseline corrected; (2) Each record component has individual acceleration (.AT2), velocity (.VT2), and displacement (.DT2) series, as well as a new column format (.AVD), which includes time, acceleration, velocity and displacement series in a single file in table format — you can open this file directly in Excel for viewing.

THESE PRELIMINARY FILES HAVE BEEN REMOVED. YOU NOW HAVE ACCESS TO THE FULL DATABASE VIA THE GROUND-MOTION PORTAL.
