NOGS January Meeting

 Update on the Coastal Geohazards Atlas

The New Orleans Geological Society (NOGS) and the Louisiana Geological Survey (LGS) began the process of developing a Coastal Geohazards Atlas in January 2018.  Since the NOGS fault atlas project began to take shape in 2015, there have been seven graduate research projects at U.N.O., Tulane and U.L.L. that have used oil and gas industry seismic data to map faults that appear to extend to the surface.  These research projects cover about 2,000 square miles of coastal Louisiana, and their results will be incorporated into the Coastal Geohazards Atlas.  NOGS and LGS are currently working with potential industry partners to dramatically expand the access to seismic data for university research.  The objective of this effort is to compile enough interpretation from university research projects to make a comprehensive atlas of faults across the surface of most of south Louisiana within the next few years.

A review of the geology of coastal Louisiana faults will cover the episodic history of fault movement from the Miocene through the recent, relationship between deltas and faults, geological controls on ecosystem evolution throughout the late Holocene, the potential impacts of faulting on transportation and flood protection infrastructure, and the importance of incorporating geology into sustainability planning.
