Figure 5. The 1D S-wave velocity profile beneath each station taken from the SCEC Velocity Model (Magistrale et al., 2000) (solid line) and the linearized version used in the analytical solution for the ray tracing (dashed line). Stations are plotted left to right, top to bottom from north to south. The depth of the basin is taken to be the point where the slope changes on the dashed line. The P-wave velocity profiles are similar but not exactly proportional to S-wave velocity.
