This electronic supplement provides finite-difference simulation results for east–west (EW), north–south (NS), and up–down (UD) directions of motion and the three-component root-sum-of-squares peak ground velocity (PGV) metric, as well as movies of the simulations for four selected scenario earthquakes.
Figure S1a. Snap-shots of simulated EW, NS, and UD wave propagation for scenario earthquake 1 from 10–80 s after the origin time of the rupture (dotted-dashed box, projected fault plane; star, hypocenter; black line, coastline).
Figure S1b. Snap-shots of simulated EW, NS, and UD wave propagation for scenario earthquake 6. See Figure S1a caption for additional information.
Figure S1c. Snap-shots of simulated EW, NS, and UD wave propagation for scenario earthquake 4a. See Figure S1a caption for additional information.
Figure S1d. Snap-shots of simulated EW, NS, and UD wave propagation for scenario earthquake 4b. See Figure S1a caption for additional information.
Figure S2. Maps of EW, NS, and UD PGV (cm/s) for all eight scenario earthquakes (dotted-dashed box, projected fault plane; star, hypocenter; black line, coastline).
Figure S3. Maps of the square root sum of squares of all three components of motion (3DrssPGV; in cm/s) for all eight scenario earthquakes; projected fault plane and hypocenter shown by dot-dashed box and star, respectively, and coastline is black line. Numbers in the upper right of each panel correspond to maximum 3DrssPGV within Greater Vancouver; dotted-dashed box, projected fault plane; star, hypocenter; and black line, coastline.
Figure S4. Basin amplification maps (3DrssPGV metric) for all eight scenario earthquakes; projected fault plane and hypocenter shown by dot-dashed box and star, respectively, and coastline is black line. Numbers in the upper right of each panel correspond to maximum basin amplification factor within the Georgia basin and Greater Vancouver regions; dotted-dashed box, projected fault plane; star, hypocenter; and black line, coastline.
Each video consists of six panels: EW (top), NS (middle), and UD (bottom) motion components for the nonbasin structure model (left) and the Georgia basin structure model (right) simulations, for the same MW 6.8 scenario earthquake. The coastline (black line) and location of highest basin amplification in Greater Vancouver (magenta square) are plotted for reference.
