The most recent earthquake, a magnitude 1.8 tremor, occurred on Monday, February 16, 2026, around 6:44 p.m. EST.

Community Impact and Expert Commentary
Despite the repeated shaking, no significant damage or injuries have been reported as a result of these recent tremors. Residents described feeling sudden and startling movements. Experts from the University of South Carolina, who monitor seismic activity across the state, emphasized that these earthquakes are minor and do not pose a significant concern.

Scientists have yet to determine the specific cause of these recent quakes.
