An unusual event in South Carolina just occurred, a magnitude 4.1 event.  At the present time, there is no reason to think this is anything but a relatively rare event.  However, it should also be recalled that Charleston, South Carolina was destroyed by a major earthquake on August 31, 1886.  Estimates place the magnitude in excess of 7, possibly as large as 7.3 moment magnitude.  So while unusual, earthquakes are not unknown in this area. 

They are generally related to the fold and fault belts of the Appalachian Mountains, in association with the Brevard fault zone, which runs into Georgia from the Carolinas.
