If you were startled during the wee morning hours on Saturday, it wasn't just your bar tab: There was a honest to goodness earthquake.
The epicenter was in Summerville near the meeting of U.S. 17A and I-26 (see map below), though there's little reason to be concerned as it was just a 3.2 on the Richter scale. It puts the shaking into the category of "often felt, but rarely causes damage."
To put that in perspective: Some 49,000 of those happen worldwide each year.
