Mystery Surrounds Intensifying 'Earthquake Swarm' Shaking South Carolina
[ZERO] A swarm of earthquakes rattled South Carolina and appeared to be getting more powerful. About 30 quakes have hit the state this year, and geologists are stumped about what's causing "earthquake swarms" similar to those felt in Southern California.

Two earthquakes hit Elgin, South Carolina, on Wednesday. The first was a magnitude 3.5, and the second 3.6, according to data from the United States Geological Survey. A 3.4 magnitude earthquake hit the state days before, while a stronger 3.9 rattled parts of the Georgia-South Carolina border on June 18.
