On June 9, 1985, a magnitude 2.6 (MD) earthquake occurred within the Savannah River Plant (SRP), South Carolina. The event was felt in an area of about 130 sq. km within the plant, with a maximum intensity III–IV (M.M.). Using stations of the SRP and South Carolina networks the event was located at 33° 13.38′N; 81° 41.73W with a depth of 0.96 km, and had an origin time of 00:38:42.93 UTC. The earthquake was located at the intersection of an inferred shallow northwest trending feature, and the northwest border fault of the Dunbarton Triassic basin. The fault plane solution suggests left lateral strike slip motion on the border fault.
