20 lines total◦1-6 on West side of highway, following most visible fault trace

◦7-12 on East side of highway, where scarp was less apparent

◦13-20 perpendicular to the proposed fault

Shear velocities at 30m depth change across the fault

Arrays on the Southwest side appear to show lower velocities than those on the NE side◦ Especially true when fault is visible on the surface

Differences in velocities become smaller the farther Southeast the arrays are set◦ Correlates with where fault becomes less apparent◦ Low velocity zone is apparent between the

vegetation lineament and projected fault trace

Results

Depth calculations allow for increased error as the angle of the dip of the layers departs from zero

Impossible to detect some geologic boundaries because of no field-measureable seismic shear-velocity contrast

Geophone placement and leveling Inconsistency in picking pf plots

Limitations
