Tremors continue in SC as another earthquake hits, but this was in different part of state
For the third day in a row an earthquake rumbled through South Carolina. But unlike the two earthquakes that were recorded over the weekend in the Columbia area, Monday’s earthquake hit in another part of the Palmetto State.
A 2.2 magnitude earthquake was recorded Monday morning in Chesterfield County, according to the U.S. Geological Survey. The previous earthquakes hit the Midlands region on Saturday and Sunday, while this one was closer to the North Carolina state line.
Monday’s earthquake was confirmed at 12:53 a.m. near Pageland, the South Carolina Emergency Management Division said. It happened about a mile beneath the surface, the USGS said.
This was the 15th confirmed earthquake this year in South Carolina, after 28 quakes were recorded in 2023, according to the state Department of Natural Resources.
A 2.1 magnitude earthquake hit Saturday afternoon and was followed by a 2.5 quake on Sunday evening, the USGS reported. Both of those earthquakes were recorded in the Elgin area of Kershaw County, according to the USGS.
Prior to this recent flurry of tremors, the last time seismic activity was recorded in South Carolina was on Sept. 1, when a 2.1 magnitude earthquake was recorded in McCormick County, state Department of Natural Resources data shows.
History of earthquakes in SC
It has been uncommon for earthquakes to hit outside of the Midlands area of the Palmetto State, specifically beyond Kershaw County, where 64 earthquakes have been confirmed since the end of June 2022, according to the South Carolina DNR.
That’s also where South Carolina’s most powerful recent earthquakes were recorded on June 29, 2022.
On that day, two earthquakes — one a 3.5 magnitude and the other 3.6 — were included in a flurry of tremors and aftershocks. Those were the two largest quakes to hit South Carolina in nearly a decade. A 4.1-magnitude quake struck McCormick County in 2014.
Anyone who felt tremors and shaking or heard rumbling from Monday morning’s earthquake can report it to the USGS.
The most recent earthquake means at least 119 have been detected in the Palmetto State since the start of 2022, according to South Carolina DNR. All but 14 of the quakes have been in the Midlands.
In all, 111 earthquakes have hit the Columbia area since a 3.3-magnitude quake was recorded Dec. 27, 2021, according to the DNR.
The S.C. Emergency Management Division said Monday morning’s earthquake was classified as a micro quake, according to the Modified Mercalli Intensity Scale.
No major damage or injuries have been reported from any of the recent quakes.
Earthquakes that register 2.5 magnitude or less often go unnoticed and are usually recorded only by a seismograph, according to Michigan Technological University. Any quake less than 5.5 magnitude is not likely to cause significant damage, the school said.
It had been typical for South Carolina to have between six and 10 earthquakes a year, the S.C. Geological Survey previously reported. There have been 133 earthquakes in South Carolina since Jan. 18, 2021, according to DNR.
During a 2022 town hall to address the earthquakes, state geologist Scott Howard said as many as 200 smaller tremors might have gone unnoticed and unrecorded.
Why the increase in earthquakes?
An explanation for the outburst has eluded scientists.
Some experts have theorized there’s a link between the Wateree River and the earthquakes northeast of Columbia. They said the combination of a single moderate earthquake in December 2022 and high water levels in the Wateree River during parts of 2022 and 2023 have contributed to the earthquakes.
But no one has settled on the single cause for the Midlands’ shaking.
Elgin, about 20 miles northeast of Columbia and situated on a fault line, experienced an unusual earthquake “swarm,” leaving some residents feeling uneasy.
The series of quakes might be the longest period of earthquake activity in the state’s history, officials said. But they don’t believe the spate of minor earthquakes is an indicator that a bigger quake could be on the way.
“Though the frequency of these minor earthquakes may alarm some, we do not expect a significantly damaging earthquake in South Carolina at this time, even though we know our state had them decades ago,” South Carolina EMD Director Kim Stenson previously said in a news release.
“Now is the time to review your insurance policies for earthquake coverage, secure any items in your home that may become hazards during a tremor and remember to drop, cover and hold on until the shaking passes. These are the precautions South Carolinians can take to properly prepare for earthquakes.”
The strongest earthquake ever recorded in South Carolina — and on the East Coast of the United States — was a devastating 7.3 in Charleston in 1886.
That quake killed 60 people and was felt over 2.5 million square miles, from Cuba to New York and Bermuda to the Mississippi River, according to the state EMD.
