Earthquake Columbia Sc: Small Quake Rattles Lexington Area as Magnitude Figures Vary
An earthquake columbia sc was felt across parts of Lexington County and Columbia on Thursday afternoon, with official measurements showing differing magnitudes and details that remain under refinement. The shallow tremor produced notable shaking in nearby communities but no immediate reports of damage or injuries.
Earthquake Columbia Sc: Magnitude, Epicenter and Depth
Measurements for the event varied in the initial coverage. One set of readings listed the magnitude as 3. 0, and another account noted an initial magnitude of 3. 4 that was later downgraded to 3. 0. A separate update cited a magnitude of 2. 5. The epicenter was placed about 2. 8 miles north of Lexington and was also described as roughly 5. 4 miles southwest of Irmo. The tremor was recorded at a shallow depth of 0 kilometers, and a horizontal location uncertainty of 1. 6 kilometers was noted.
Felt Area, Local Landmarks and Immediate Impact
The quake was felt in communities around Lexington and Columbia, with specific mentions of Irmo, Seven Oaks, Oak Grove, and Columbia, which is approximately 12 miles east of the identified epicenter. The event was detected near Lake Murray in Lexington County and was felt in parts of the Midlands. Despite the perceptible shaking — enough to rattle windows or cause minor shaking — no damage or injuries were immediately reported.
What This Means and What to Watch For
Variations in the listed magnitude underscore that initial seismic readings can change as instruments are reanalyzed and updates are issued. The presence of a shallow depth can make even a small earthquake more noticeable at the surface. Observers in the affected area experienced short-lived shaking, and officials characterized the situation as stable with no immediate reports of harm.
This remains a developing situation in the sense that magnitude figures and technical details were revised in early updates. Additional refinements to the event parameters or follow-up notices could appear as measurements are refined. For residents in the region, awareness of aftershocks and any further official guidance is prudent, though there were no immediate indications of ongoing risk reported in the initial coverage.
Quick reference: reported details
- Reported magnitudes in early updates: 2. 5, 3. 0, and an initial 3. 4 later adjusted to 3. 0
- Approximate epicenter: about 2. 8 miles north of Lexington; also cited about 5. 4 miles southwest of Irmo
- Depth listed: 0 kilometers
- Horizontal location uncertainty: 1. 6 kilometers
- Areas that felt the tremor: Irmo, Seven Oaks, Oak Grove, Columbia, and nearby communities
- Immediate impact: no damage or injuries were immediately reported
As more refined information becomes available, technical details may be updated. For now, the event stands out as a shallow, small-magnitude earthquake that was widely felt across parts of Lexington County and Columbia.
