Electronic Supplement to
Ground-Motion Prediction Equations for Arias Intensity, Cumulative Absolute Velocity, and Peak Incremental Ground Velocity for Rock Sites in Different Tectonic Environments

by Zach Bullock, Shideh Dashti, Abbie Liel, Keith Porter, Zana Karimi, and Brendon Bradley

This electronic supplement provides figures that were not included in the main article for brevity, as well as tables of all ground motions used.

Figures S1–S6 present the model residuals for Arias intensity (IA); Figures S7–S12 present the model residuals for peak incremental ground velocity (Vgi); Figures S13–S18 present the model residuals for cumulative absolute velocity above a 5 cm/s2 threshold (CAV5); and Figures S19–S22 present the model residuals for standardized cumulative absolute velocity (CAVSTD).

Figures S23 and S24 show model comparisons for IA for the shallow crustal and subduction tectonic environments, respectively. Figure S23 provides only the model medians because three models are being compared. Figure S25 shows the attenuation for IA in the intraplate tectonic environment. Figures S26, S27, and S28 show the attenuation for CAV5 in the crustal, subduction, and intraplate tectonic environments, respectively. Figures S29 and S30 show the same for CAVSTD in the shallow crustal and subduction tectonic environments, respectively. Figures S31–S33 show the same for Vgi in all three tectonic environments. Figures S25–S33 show only the attenuation for the models presented in this study.

Tables of metadata for all records included in the shallow crustal, intraplate, and subduction databases are provided as separate comma-separated variable (CSV) files.
