A second earthquake on the same day rocks the Columbia area of ​​South Carolina

By | March 10, 2024

For the second time on the same day, an earthquake rocked the Columbia area.

A magnitude 1.3 earthquake was recorded in the Midlands on Saturday night, according to the US Geographical Survey. The earthquake occurred about 14 hours after tremors hit the same part of the Midlands.

The second earthquake was confirmed near Elgin at 11:40 p.m., according to the South Carolina Emergency Management Division. That’s in Kershaw County.

Saturday night’s earthquake occurred about a mile below the surface, according to the USGS.

Saturday morning’s earthquake had a magnitude of 2.83 and occurred at 9:27 a.m., about 1.75 miles (2.75 kilometers) below the surface, the USGS reported. It was just south of where Saturday night’s shaking was recorded, but still in the Elgin area, according to the USGS.

The second quake was the fourth confirmed quake in 2024, after 28 earthquakes were recorded in South Carolina in 2023, the state Department of Natural Resources said.

It is unusual for earthquakes to occur outside the Midlands area of ​​the Palmetto State, especially outside Kershaw County, where 58 earthquakes have been confirmed since the end of June 2022, according to the South Carolina DNR.

That’s also where the most powerful recent earthquakes in South Carolina were recorded on June 29, 2022. On that day, two earthquakes – one with a magnitude of 3.5 and the other with a magnitude of 3.6 – were included in a wave of tremors and aftershocks. Those were the two largest earthquakes to hit South Carolina in nearly a decade. McCormick County was hit by a magnitude 4.1 earthquake in 2014.

Anyone who felt shaking, shaking or heard rumbling from Saturday night’s earthquake can report it to the USGS.

At least 108 earthquakes have been recorded in the Palmetto State since early 2022, according to the South Carolina DNR. All but ten of the earthquakes occurred in the Midlands.

According to the DNR, a total of 103 earthquakes have struck the Columbia area since a magnitude 3.3 earthquake was recorded on December 27, 2021.

The SC Emergency Management Division said Saturday evening earthquake was classified as a microquakeaccording to the modified Mercalli intensity scale.

No major damage or injuries have been reported as a result of the recent earthquakes.

Earthquakes with a magnitude of 2.5 or less often go unnoticed and are usually only recorded by a seismograph, according to Michigan Technological University. Any earthquake with a magnitude of less than 5.5 is unlikely to cause significant damage, the school said.

It was typical for South Carolina to experience between six and 10 earthquakes per year, the SC Geological Survey previously reported. According to DNR, there have been 122 earthquakes in South Carolina since January 18, 2021.

At a 2022 town hall to address the earthquakes, state geologist Scott Howard said as many as 200 smaller tremors may have gone unnoticed and unrecorded.

Why the increase in earthquakes?

An explanation for the eruption has eluded scientists.

Some experts have theorized that there is a link between the Wateree River and the earthquakes northeast of Columbia. They said the combination of a single moderate earthquake last December and high water levels in the Wateree River during parts of 2022 and 2023 contributed to the earthquakes. But no one has spoken out about the sole cause of the Midlands’ shaking.

Elgin, located about 20 miles (32 kilometers) northeast of Columbia and situated on a fault line, experienced an unusual earthquake swarm last year, leaving some residents uneasy. The series of earthquakes could be the longest period of earthquake activity in the state’s history, officials said. But officials have said they do not believe the wave of small earthquakes is an indicator that a larger quake is on the way.

“While the frequency of these small earthquakes alarms 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 said earlier in a statement news item. Edition. “Now is the time to review your insurance policies for earthquake coverage, secure any items in your home that could pose a hazard during a quake, and remember to drop, cover, and hold on until the shaking passes is. These are the precautions South Carolina residents 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 earthquake killed 60 people and was felt across 1.5 million square miles, from Cuba to New York and from Bermuda to the Mississippi River, according to state EMD.
