Earthquake
History shows that earthquakes do happen in Georgia, although the most recent great earthquake in the region was in 1886 when Charleston, South Carolina, was devastated. That earthquake and four New Madrid earthquakes, centered in the Mississippi valley in 1811 – 1812, caused as much damage in Georgia as all the earthquakes centered within the state’s borders combined.

The area around Dacula, a few miles east of Lawrenceville, experienced a swarm of small earthquakes in Fall 1995 and Winter 1996.

Major earthquakes in the eastern United States happen about once every 100 years, but the probability of such an event causing damage in Georgia within the next year is about one in 1,000.

Seismic monitoring of significant U.S. earthquakes is coordinated by the U.S. Geological Survey (USGS). Small local earthquakes are monitored by nearby regional networks, including The Georgia Institute of Technology and The Center for Earthquake Research and Information at Memphis State University.
