What happened on August 31 1886 in Charleston before the earthquake?

Is SC 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.

Is SC on a major fault line?

What makes South Carolina earthquakes somewhat unusual, though, is that the state does not sit near any major fault lines, or boundaries between tectonic plates in the earth’s outer layer, the way the western United States does. The state does, however, experience what are known as intraplate earthquakes.

The cause of earthquakes in South Carolina is not so clear. South Carolina’s quakes are located within a plate rather than at a plate boundary. Perhaps the intraplate quakes felt in South Carolina are the result of stresses transmitted inward from the boundaries of the North American plate.
