Shallow seismic reflection investigations of neotectonic activity in the Lower Mississippi Valley


Shallow shear wave seismic reflection methods were used to help interpret the significance of neotectonic surface deformation at three sites in the Lower Mississippi Valley. The seismic data were acquired with a hammer and mass energy source and processed using a standard sequence for shallow reflection data. The interpreted profiles show a range of shallow structural styles that includes reverse faulting, fault propagation folding, and reactivated normal faulting. Determining the style and extent of near-surface structural deformation is critical in evaluating the seismic potential of an area.
