COLUMBIA, S.C. — A second earthquake in three days rattled the Irmo area of South Carolina late Sunday, according to the United States Geological Survey (USGS). The latest tremor, registering a magnitude of 2.0, was detected around midnight approximately three miles west of Irmo.
This follows a magnitude 2.8 earthquake reported Friday night in the same vicinity, as previously reported by WIS. The USGS has been monitoring seismic activity in the region following these recent events.
While these earthquakes are relatively minor in magnitude, they are notable as the second instance of seismic activity in the area within a short timeframe. The State reports that three earthquakes have rumbled under Irmo in a four-day stretch.
Earthquake magnitudes are measured on a logarithmic scale, meaning each whole number increase represents a tenfold increase in amplitude. A magnitude 2.0 earthquake is generally felt by some people, but rarely causes damage. A magnitude 2.8, like the one reported Friday, is also typically felt but unlikely to cause significant structural issues.
Residents in the Irmo area may have experienced slight shaking or vibrations as a result of these events. There have been no immediate reports of damage or injuries related to either earthquake.
The cause of the recent seismic activity is currently under investigation. South Carolina is not typically considered a high-risk earthquake zone, but minor tremors do occur periodically. The state is located within the broader seismic zone of the eastern United States, which experiences infrequent but occasionally noticeable earthquakes.
