Greenwood County, South Carolina Experiences Back-to-Back Earthquakes
In Greenwood County, South Carolina, seismic activity has captured the attention of residents and experts alike. For the second time in just four days, an earthquake was confirmed in the area. A 2.4 magnitude earthquake struck early Sunday morning, September 15, 2024, around 4:48 a.m., as reported by the U.S. Geological Survey (USGS).
What Happened?
Sunday’s earthquake was significant enough to be classified among the strongest recorded in the Palmetto State in 2024. It hit at a depth of approximately 2.5 miles beneath the surface. This tremor follows another earthquake that occurred just four days prior, recorded at a 2.2 magnitude in nearly the same location. The string of seismic events has raised questions and concerns among residents, as well as state officials.
Where Did It Occur?
The earthquakes were centered near Coronaca, a small community within Greenwood County. This region has seen an unusual uptick in seismic activity recently, coinciding with a state-wide initiative known as S.C. Earthquake Preparedness Week.
When Did This Happen?
The first earthquake occurred on Thursday, September 12, 2024, while the second tremor shook the region in the early hours of Sunday morning. This increased seismic activity aligns with broader patterns seen in South Carolina’s earthquake history.
Why Is This Relevant?
These back-to-back earthquakes are part of a trend where South Carolina has recorded its 18th confirmed earthquake this year, following the 28 recorded in 2023. State officials noted the recent seismic activity provides an opportunity for residents to reassess their emergency preparedness plans. Since January 2022, over 122 earthquakes have been detected in the state, most of them occurring in the Midlands region, particularly near Columbia.
What Do The Experts Say?
While Monday’s tremor was classified as a microquake by the South Carolina Emergency Management Division, it is notable that earthquakes of this size and magnitude are typically not associated with significant damage or injury. Officials stated that earthquakes registering below 5.5 are unlikely to cause substantial destruction. Experts also indicated that the frequency of smaller quakes should not cause alarm regarding the potential for a larger, more impactful earthquake.
Local Impact and Preparations
No major damage or injuries have been reported as a result of either earthquake. Residents are encouraged to report any felt tremors to the USGS to help build a better understanding of earthquake patterns in the region. The state geologist, Scott Howard, explained that aftershocks and tremors might contribute to a feeling of unease among the local populace.
Looking Ahead
As part of Earthquake Preparedness Week, South Carolinians are urged to review their earthquake insurance policies and secure items in their homes that could become dangerous during a tremor. It is recommended to practice evacuation drills and understand the basic safety measures: drop, cover, and hold on during shaking.
Historical Context
Historically, South Carolina has been the site of significant seismic events, including the devastating 7.3 magnitude quake that struck Charleston in 1886, resulting in fatalities and extensive damage over a vast area. The current seismic activity serves as a reminder of the state’s geological history and the importance of being prepared for natural disasters.
As residents of Greenwood County and surrounding areas remain vigilant, state officials continue to monitor seismic trends and encourage preparedness for any future occurrences. The recent earthquakes are a call to action for individuals to stay informed and ready for natural events, ensuring their safety and the safety of the community.
