This electronic supplement includes figures for residuals, peak ground acceleration (PGA), spectral accelerations (SAs) at the periods of 0.5 and 1.0 s, and peak ground velocity (PGV). There are five figures in each category. These figures correspond to the figures for SAs at 0.2 s that are provided in the main article.
Figure S1. Normalized log residuals for PGA versus hypocentral distance for (a) induced and (b) tectonic earthquakes. Each row of the subplots contains residuals from earthquakes with the stated magnitude range. The mean and standard deviation of error bars are calculated using distance bins of ±4 km centered at the marker.
Figure S2. Normalized log residuals for PGA versus magnitude for (a) induced and (b) tectonic earthquakes. Each row of the subplots contains residuals from earthquakes with the stated hypocentral distance (Rhyp) range. The mean and standard deviation of error bars are calculated at each indicated magnitude.
Figure S3. Median PGA values predicted by the ground-motion prediction equations (GMPEs) for three hypocentral distances, as indicated on each subplot.
Figure S4. Observed PGA values for (a) induced and (b) tectonic earthquakes, with median estimated accelerations from Atkinson (2015, hereafter, A15) and Shahjouei and Pezeshk (2016, hereafter, SP16). Each row of the subplots includes observations from the stated magnitude range. GMPEs are evaluated at the middle of the magnitude bins.
Figure S5. Observed PGA values from Texas, Oklahoma, and Kansas, with median estimated accelerations from A15 and SP16. Each subplot includes observations from the stated magnitude range and GMPE predictions for the middle of the magnitude bin.
Figure S6. Normalized log residuals for SA0.5 versus hypocentral distance for (a) induced and (b) tectonic earthquakes.
