South Carolina residents were hit with yet another earthquake early this week. Making this event was one of many to hit the state over the last year; leading experts to wonder if a previously dormant Appalachain faultline has now become active again.

On Sunday afternoon around 3 p.m., a low-level earthquake was detected close to the Ladson area in the Lowcountry part of the state. This area sits near South Carolina’s Dorchester, Charleston, and Berkeley counties. According to the U.S. Geological Survey, an earthquake measuring with a magnitude of 1.4 occurred Sunday afternoon. There were no major damages or injuries reported in this most recent earthquake.

Experts Searching For the Cause of Unusual South Carolina Earthquakes

As per the New York Post, the region in which the earthquakes are occurring sits near a regional fault system. This is a system that was created during the formation of the Appalachian Mountains. These fault systems have long been dormant, experts note. However, the recent activity suggests that they may be “waking” back up.

“If they don’t get any bigger, they are more of an annoyance than a concern,” notes Steven Jaume a geology professor at the College of Charleston of the recent earthquakes.

“I am envious of meteorologists because they can see the storms coming,” Jaume adds. “We can’t see earthquakes coming there is nothing we can record that tells us something bigger is coming.”

Area Has Recorded Mutliple Earthquakes In A Short Period of Time

The depth of the Sunday afternoon seismic activity has a recorded depth of 2.9 kilometers. This translates to a depth of about 1.8 miles. This South Carolina earthquake is the fourth to be recorded in the Palmetto State in the early days of 2022. Twenty-four events have hit the area since the fall of 2020.

The earthquakes reported earlier this year were all recorded in another area in South Carolina. These occurred in the Midlands area of the state rather than the most recent location of similar activity in Lowcountry.

The previous 2022 earthquakes were all recorded near Columbia South Carolina in Kershaw County.

Since December 10 of last year, the South Carolina region has reported a total of ten earthquakes. Each one of these earlier events has occurred within the Elgin and Lugoff areas of South Carolina. Juame adds that experts are scrambling to figure out what is causing these events to occur within a shockingly short nine-day period.

“They’re not dying away the way we would expect them to,” Jaume says of the unusual events. “What does that mean? I don’t know.”
