Synthesis of Faults Traces in SE Louisiana Relative to Infrastructure

Geological faulting has been implicated as a contributor to subsidence, coastal land loss, and submergence of marshlands in southern Louisiana. Fault motion, either by slow creep or more sudden slip, can cause deformation of engineered structures. In addition, the compaction of thick soils and Holocene sediments on the down-dropped sides of faults contributes to land subsidence that can result in increased infrastructure maintenance and repair costs. This project will synthesize current fault mapping and produce fault trace maps relative to critical infrastructure in areas underlain by existing three dimensional (3D) seismic surveys, and in other areas having a high density of wells and two dimensional (2D) seismic data.
