An unprecedented wave of minor earthquakes focused near Elgin, a small town in Kershaw County in South Carolina, have local residents struggling to describe what they’re experiencing. For a big chunk of 2022, “Did you feel that?” became almost as common a greeting as “How are you?” across the Midlands. The U.S. Geological Survey refers to the Elgin phenomenon as a “swarm.” It began Dec. 27, 2021, with a magnitude 3.3 earthquake. Since then, upward of 80 earthquakes have been recorded. Zhigang Peng, a professor of geophysics in the School of Earth and Atmospheric Sciences, says magma or fluid movement can cause quakes, but scientists haven't found evidence of those with the Elgin swarm.
