For the second time in less than a week, an earthquake hit South Carolina.

A 2.1 magnitude earthquake was recorded Sunday morning in McCormick County, according to the U.S. Geological Survey. Not only was it South Carolina’s second confirmed earthquake in a six day span, it also was recorded near the same part of the Palmetto State where the previous quake occurred.

Sunday’s earthquake was confirmed at 2:53 a.m. near Jackson, the South Carolina Emergency Management Division said.

The earthquake happened about half 3.5 miles beneath the surface, according to the USGS.

This was the 12^th confirmed earthquake this year in South Carolina, after 28 quakes were recorded in 2023, according to the state Department of Natural Resources.

The last time seismic activity was recorded in South Carolina was on Aug. 26, when tremors were recorded as a 1.9 magnitude earthquake hit in the Jackson area of Aiken County, state Department of Natural Resources data shows.

This was the first earthquake recorded in McCormick County since May 25, 2019, and it’s only the third time since 2006 that seismic activity has been confirmed there, according to the USGS.

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 62 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 Sunday morning’s earthquake can report it to the USGS.

The most recent earthquake means at least 116 have been detected in the Palmetto State since the start of 2022, according to South Carolina DNR. All but 13 of the quakes have been in the Midlands.

In all, 108 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 Sunday 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 130 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.

COLUMBIA — South Carolina football won Saturday’s season opener against Old Dominion 23-19 at Williams-Brice Stadium, but it was far from a perfect game for the Gamecocks.

Coach Shane Beamer made it clear in his opening statement after the game that South Carolina will celebrate the win, but thought almost all three levels of play were full of mistakes.

“Unacceptable from us in the way we performed, starting with me,” Beamer said. “Winning is hard … sloppy without a doubt, on all three phases, lots to clean up … did some good, did some bad, so we have to coach better without a doubt.”

South Carolina was led by redshirt freshman LaNorris Sellers at quarterback, and had true freshman on both sides of the field. Dylan Stewart, Josiah Thompson, Mazeo Bennett, and Michael Smith all played their first college game.

“We aren’t the only the school in the country playing true freshman and we have to put them in position to make plays.” Beamer said. “I told those guys coming out of half, you ain’t a freshman anymore, you played a half of SEC football, we are past that excuse.”

What Beamer did draw attention to was the Gamecocks’ self-inflicted errors, like dropped passes and penalties. The Gamecocks were called for two penalties that eliminated scoring chances, and only completed 10 passes for 114 yards. Sellers fumbled on a drive in the first quarter, and knocked over his own player while trying to block for running back Juju McDowell.

“Let’s not beat ourselves, I thought we had too much of that tonight,” Beamer said. “It start’s with us as coaches and we will do a better job of getting that cleaned up.”

Quick notes from South Carolina Athletics

QUICKLY: The South Carolina Gamecocks begin the fourth year of the Shane Beamer Era in non-conference fashion when they host the Old Dominion Monarchs out of the Sun Belt Conference at Williams- Brice Stadium (77,559) in Columbia, S.C. on Saturday, Aug. 31. Game time has been set for 4:15 pm ET.

OVER THE AIRWAVES: The 2024 season opener will be televised on the SEC Network. Long-time SEC play-by-play voice Dave Neal will call the action, with former Georgia quarterback Aaron Murray providing the color commentary. Ashley ShahAmadi will patrol the sidelines. The Gamecock Sports Radio Network features a pair of Gamecock great quarterbacks in Todd Ellis (33rd season) and Tommy Suggs (52nd season) in the booth. Chet Tucker returns for his second season as the network’s sideline reporter.

A LITTLE HISTORY: 2024 marks year four of the Shane Beamer Era and the 131st season of intercollegiate football at the University of South Carolina, dating back to 1892. It is the 118th-consecutive year in which South Carolina has competed on the gridiron. The University did not field a team in either 1893 or 1906. Carolina owns an all-time record of 634-613-44, a .508 winning percentage. Since the start of the 21st century, the Gamecocks have posted a 168-131 record, a .562 winning clip. In three seasons under Coach Beamer, the Gamecocks are 20-18, a .526 winning percentage.

OPENING REMARKS: Through 130 years of intercollegiate football, the Gamecocks have compiled an 86- 40-4 record in season openers, a winning percentage of .677. In the 97 seasons in which the Gamecocks have opened at home, the record is a very impressive 73-20-4, which translates into a .773 winning mark. In 28 seasons in which the Gamecocks have opened on the road, they are 10-18 for a .357 winning pct. South Carolina opened the 2011, 2015, 2017, 2019, and 2023 seasons at a neutral site, posting a 3-2 record in those five contests. Carolina has won all three of its home openers under Coach Beamer.

IT JUST MEANS MORE: The 2024 season will mark South Carolina’s 33rd year in the Southeastern Conference. South Carolina and Arkansas joined the SEC prior to the 1992 campaign. The Gamecocks earned the SEC Eastern Division title in the 2010 season. The Gamecocks are 109-148-1 (.424) all-time in SEC regular season play but posted a 42-38 (.525) record in conference action from 2010-19. Under Coach Beamer, the Gamecocks are 10-14 in SEC play, a .417 winning percentage.

YOU’RE SIXTEEN: The Southeastern Conference will take on a new look in 2024 with the addition of blue blood programs in Texas and Oklahoma. The Gamecocks will not face the Longhorns in 2024 but will travel to Norman for their first encounter with the Sooners on Oct. 19. With the additions of the two schools, the league will no longer be divided into two divisions, but rather just one 16-team conference with the top two finishers advancing to Atlanta for the SEC Championship game on Dec. 7.

TOUGH SLATE: South Carolina has one of the nation’s toughest schedules in 2024, as seven of its 12 regular-season opponents are ranked in the nation’s preseason top 20. The Gamecocks’ 2024 slate includes contests against Alabama (5/5), Ole Miss (6/6), Missouri (11/11), LSU (13/12), Clemson (14/14), Oklahoma (16/16), and Texas A&M (20/20).
