Figure 4. Four vertical and surface time slices of M6.5 earthquake simulation on the Seattle fault. Vector magnitude of three velocity components (N-S, E-W, and vertical) are presented. Surface slices: red line is the location of vertical time slice, green 'S' is downtown Seattle, white lines are coastlines, and orange box is surface projection of fault plane. Vertical slices: magenta line is the Quaternary/Tertiary impedance boundary, black line is the top of Crescent, and green line is the fault plane. Much of the high-amplitude motion is focussed in the near-surface.
