Does South Carolina lie on a fault line?
South Carolina’s Fault System: These cracks in the deep rocks mean that this area of the plate is weak. If pressure is exerted on the edge of the plate, some of these faults/breaks will allow the rocks to move. Faults in South Carolina have been mapped and estimated. Fault rupture is not the only cause of earthquakes.
