South Carolina was rocked by several earthquakes Wednesday, including the two strongest yet in a “swarm” of earthquakes that have rattled the state this year according to USA Today.
Two quakes that are unusually strong for the region struck central South Carolina on Wednesday — a magnitude 3.5 and a magnitude 3.6, according to data from the United States Geological Survey. Over the weekend, a magnitude 3.4 earthquake also shook the state.
The quakes are the most powerful to hit the state in years, and at least one of Wednesday’s tremblers could be felt near Charlotte, North Carolina, according to reports published by the United States Geological Survey.
In a video shared by the state’s Emergency Management Division, geologist Wendy Bohon said more than 30 quakes have hit the state this year, a part of an “earthquake swarm.” Such swarms are familiar occurrences in more earthquake-prone areas, but less common in the South.
The South Carolina swarm has been going on for over half a year and included seven quakes above a magnitude 3, according to seismologist Lucy Jones. “Swarms happen in all seismic regions and the earthquakes continue until they stop,” Jones tweeted.
“That may not seem helpful, but knowing this is normal can help.” The latest quakes occurred near Elgin, South Carolina, according to data from the United States Geological Survey. The town is located about 20 miles northeast of Columbia, the state’s capital.
