Here's the problem with that.
I am a resident of GA, and know a little bit about our geography here.
There are 7 rock quarries listed when you google "quarries in Athens, GA"--but none of them are actually "IN" Athens.
In fact, many of those listed below are over 25 miles AWAY from Athens, or more.
And---since when can the USGS not be able to tell the difference between a blast for mining rock, and an earthquake???!?
The rock quarry 3 miles from my house (which is NOT one of the ones listed below) has blasting every day around noon, which slightly shakes my house, but the USGS has never mistaken one of THOSE for an earthquake.
Something's fishy, here...
