Quakes Close to Columbia, SC

[Michigan Swamp Buck]

I was going to mention the New Madrid Fault, however, that's pretty far to the west. Sounds like a different fault line. We have a few in Michigan, but those are more like extensions of the New Madrid lines as we are in the moderate to low damage seismic zone and have had some small quakes in my lifetime. The western half of SC is in the low seismic zone of the NMFL.
