Background on Earthquake Activity

Earthquakes are a natural phenomenon caused by the movement and shifting of tectonic plates beneath the earth’s surface. The frequency of tremors can vary greatly by region, and areas like Greenwood County can experience multiple seismic events over a short period. The USGS continuously monitors earthquake activity and provides notifications to help inform local populations. Such notifications become particularly important when seismic activity increases, as in this recent case.

Residents and officials are advised to remain aware of their surroundings during these seismic events and to follow safety recommendations provided by local authorities. Keeping emergency supplies and having a plan can be beneficial in the chance of more significant seismic activity in the future.
