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

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
