This report contains ground motion prediction equations (GMPEs) for a particular measure of horizontal component ground motions as a function of earthquake mechanism, distance from source to site, local average shear wave velocity, and fault type. The equations are for peak ground acceleration (PGA), peak ground velocity (PGV), and 5% damped pseudo-absolute-acceleration spectra (PSA) at periods between 0.01 and 10 s. The equations were derived by empirical regression of the PEER NGA strong-motion database. For periods of less than 1 s, the analysis used 1574 records from 58 mainshocks in the distance range from 0 k km to 400 km (the number of available data decreased as period increased).
