Book excerpt: This study presents empirical ground motion prediction equations (GMPEs) for eastern North America for a particular measure of horizontal ground motion as a function of earthquake magnitude and fault type, distance from source to site, and local soil condition. The equations are for peak ground acceleration (PGA), peak ground velocity (PGV), and 5 % damped pseudo-absolute-acceleration spectra (PSA) at periods between 0.02 sec and 1 sec. The coefficients of the GMPEs are derived by empirical regression of the new NGA-East ground motion database. The anlysis used a total of 6544 records of PGA with a distance range from less than 10 km up to 3500 km and the available data for regression become less for longer periods. The developed empirical GMPEs, though not well constrained from large magnitude observations, fit the ground motions from small to moderate magnitude (M
