Report of Investigations--KGS


From January 2013 to December 2017, the Kentucky Geological Survey monitored earthquakes and conducted research on seismic hazards in the vicinity of the Paducah Gaseous Diffusion Plant, a former uranium enrichment facility, in western Kentucky. Fifteen earthquakes with magnitude greater than 3.0 occurred in the area during this period, and data were collected from the Central U.S. Seismic Observatory and the vertical seismic array at the gaseous diffusion plant. This monitoring improved our understanding of seismic-wave propagation through thick sediments and ground-motion site effects, as well as fault locations in the New Madrid Seismic Zone, ground-motion attenuation, and seismic-hazard assessment. Results have been communicated through publications and presentations at workshops and conferences. The data will contribute to the development of design ground motions for western Kentucky, and specifically for buildings and facilities at the Paducah Gaseous Diffusion Plant.

Statement of Benefit to Kentucky

Continuing efforts to monitor earthquakes and conduct research have enhanced our understanding of seismic hazards in western Kentucky, which in turn has contributed to a sound scientific basis for developing design ground motions for buildings and facilities in western Kentucky, in particular at the Paducah Gaseous Diffusion Plant.
