Georgia still has a number of fault lines though. That’s where most earthquakes occur. The Brevard Fault Line, the best-known one, runs from Blue Ridge to Marietta. The Soque River Fault follows the Sogue River in the Northeast, and Salacoa Creek is in Northwest Cherokee County.

What tectonic plate is Georgia on?

Where is the Brevard Fault Line in Georgia?
The Brevard Fault Zone extends across the Pied- mont of western Georgia and eastern Alabama, crossing stratigraphic and structural entities. The present paper concerns the segment of the Brevard that extends from Atlanta, Ga., southwestward to Roanoke, Ala., a distance of about 128 km (80 miles).
