A number of ground‐motion prediction equations (GMPEs) have been introduced in recent years that are redefining the state of practice for probabilistic seismic‐hazard analysis (PSHA) in many earthquake‐prone regions worldwide. For example, the Next Generation Attenuation (NGA)‐East is developing a new ground‐motion characterization (GMC) model for the central and eastern North American (CENA) region. The GMC model will consist of a set of new GMPEs for median and standard deviation of ground motions and their associated weights in the logic trees for use in PSHA. An example is the empirical GMPE by Al Noman (2013).
