• A Ground Motion Prediction Equation for the Horizontal Component of Cumulative Absolute Velocity (CAV) Based on the PEER-NGA Strong Motion Database (2010, methodology): “This definition of the horizontal geometric mean is different from the GMRotI50 horizontal component used in the NGA-West Project (Boore et al. 2006), which is an orientationindependent version of the geometric mean.”
• Orientation-independent, nongeometric-mean measures of seismic intensity from two horizontal components of motion (2010, methodology): “Boore et al. (2006) introduced a measure of response spectra that was also independent of the in situ orientations of the sensors but corresponded to a single rotation angle for all oscillator periods.”
• NGA Project Strong-Motion Database (2008, methodology): “For the development of NGA models, the two horizontal acceleration components were further rotated to form the orientation-independent measure of horizontal ground motion (GMRotI50, Boore et al., 2006).”
• Repeatable Source, Site, and Path Effects on the Standard Deviation for Empirical Ground-Motion Prediction Models (2011, methodology): “The orientation-independent measurement of average horizontal amplitude, GMRotI50 (Boore et al., 2006), was also computed and included in the database.”
• Correlation of Spectral Acceleration Values from NGA Ground Motion Models (2008, methodology): “Empirical correlation coefficients from four NGA GMMs (Abrahamson and Silva 2008, Boore and Atkinson 2008, Campbell and Bozorgnia 2008, Chiou and Youngs 2008), at a variety of period pairs, are shown in Figure 2 and Figure 3.”
• Statistical Tests of the Joint Distribution of Spectral Acceleration Values (2008, methodology): “This is the fiftieth percentile of the set of geometric means of spectral accelerations at a given period, obtained by rotating the as-recorded orthogonal horizontal motions through all possible nonredundant rotation angles (Boore et al., 2006).”
• Empirical Evaluation of Hierarchical Ground‐Motion Models: Score Uncertainty and Model Weighting (2017, methodology): “We acknowledge that the definition of peak motions used by the NGA GMMs is GMrotI50 (Boore et al., 2006), whereas that used in the NGA-West 2 flatfile is rotD50 (Boore, 2010).”
• Truncation of the distribution of ground-motion residuals (2008, methodology): “The horizontal component definition used is the median value of the geometric mean of the two horizontal components rotated over the non-redundant range of rotation angles (GMRotD50), as defined by Boore et al. (2006).”
• Rupture dynamics and ground motion from 3‐D rough‐fault simulations (2013, background): “Therefore, recent empirical ground-motion prediction equations (GMPEs) have adopted orientation-independent averages of the component intensity measures, e.g., the so-called GMRotD50 and GMRotI50 values [Boore et al., 2006].”
