Earthquake history of South Carolina

An estimated $23 million damage was caused by one of the great earthquakes in United States history in 1886. Charleston, S.C, and nearby cities suffered most of the damage, although points as far as 160 km away were strongly shaken. Many of the 20 earthquakes of intensity V or greater (Modified Mercalli scale) that centered within South Carolina occurred near Charleston. A 1924 shock in the western part of the State was felt over 145,000 km². Several earthquakes outside the State borders were felt strongly in South Carolina.
