Ground motion values from the lowest misfit validation simulations plotted as a function of magnitude for PGA (top left), PGV (top right), and dominant frequency (bottom left). The ground motions have been normalized to a distance of 10 km. Symbols are plotted at the median level and error bars denote the standard deviation. JA19_S2 and JA19 are double-corner-frequency models of Ji and Archuleta (2021), and BH14 is the single-corner-frequency model of Baltay and Hanks (2014). Aa and Av denote the amplification factors applied to the empirical models for PGA and PGV, respectively, in determining the optimal fit to the simulated ground motions. E denotes the misfit given by Eq. (14)
