Black Friday began with a bang in New Jersey, literally.
A 2.1-magnitude earthquake was measured a little after midnight near Clementon, Camden Co., about 15 miles southeast of Philadelphia.
It was the second earthquake to hit New Jersey this month. On Nov. 5, a 2.0-magnitude quake struck the Ringwood area in Passaic County.
A rare 5.8-magnitude East Coast earthquake centered in Virginia rattled both New Jersey and Pennsylvania in August 2011, wobbling floors and shaking buildings.
