Earth Quake

The third Earthquake to hit the east coast since the 1600s, hit the Rickmond/D.C. Area today.

What in the world. I mean there's been some earthquakes at the continental shelf but that's far out into the ocean
two in 1970, one in 1992, one in 2009, and one in 2010.
But since the 1600s, in the United States, there has only been three on the east coast. In 1998 there was one in Pennsylvania. In 2010 there was a barely noticeable one in the DC metropolitan area, and now 2011 in Richmond Virginia and the DC metropolitan area there is a quite noticeble one, being a 5.9 on the rictor scale.
