People around South Jersey might have thought they were imagining a portent of things when a rumble went through the area shortly after midnight when stores opened their doors on Black Friday.
But, it was a small earthquake centered near Clementon, Camden County, that started the day with shudder.
According to the U.S. Geological Survey, the 2.1-magnitude earthquake was centered in the small town 15 miles southeast of Philadelphia.
It was nothing like the 5.8-magnitude earthquake centered in Virginia that rattled New Jersey and Philadelphia in August 2011. That one wobbled floors and shook buildings.
