Earthquakes in Georgia: How common are they?

Georgia has seen over 200 earthquakes since 1900, but how does that compare to places like California?

In order to talk frequency of earthquakes, we need to look at the big picture.

Here in North America, we mainly sit on the North American plate. California is the exception.

In California, the North American and Pacific plates meet, resulting in the infamous San Andreas fault.

Since 1900, only about 240 earthquakes have occurred in Georgia.

To put that into perspective, on July 7, 2019 alone, the USGS reported 158 earthquakes in California with a magnitude of 2.5 or higher.

Most of Georgia's quakes happen along the Brevard fault zone, which has been the focal point for over 100 earthquakes in northwest Georgia in over a century. 

Lake Sinclair has been a hot spot for smaller-scale earthquakes as well.

These earthquakes are due to changing water levels, known as reservoir-induced seismic activity.

The rising water levels puts shifts sediments on the floor, and puts more pressure on old fault lines below.

The most recent earthquake here in Central Georgia was a 2.4 magnitude quake in Jones County in June of 2018.
