Earthquake levels increase by a factor of 10, so a 4.0 magnitude earthquake is actually 10 times stronger than a 3.0, and a 5.0 is 100 times stronger than a 3.0.

A small 2.7 earthquake was registered in early January 2018 in northeast Georgia, The Atlanta Journal-Constitution previously reported.
The area about 30 miles away in Trion felt a similar quake in early November 2017, according to previous AJC reports.
A magnitude 2.5 earthquake struck an area about 100 miles southeast of downtown Atlanta in April 2017 and a 2.5 magnitude quake hit in Augusta later in the month. A stronger earthquake of 3.2 magnitude hit Augusta in June last year.
The apparent increase of reported earthquakes isn’t a sign of anything abnormal, officials say. Instead, the reports are a reflection of better equipment for measuring seismic activity.
The National Earthquake Information Center now locates about 20,000 earthquakes each year, or approximately 55 per day. As a result of the improvements in communications and the increased interest in natural disasters, the public now learns about earthquakes more quickly than ever before.
