It wasn't the shakeup many people want to happen in the nation's capital, but a moderate earthquake struck Washington D.C. at 5:04 Friday morning.  The quake was a 3.6 and was centered in Rockville, Maryland at a depth of 3.1 miles.  It was the strongest event recorded in the area since records started being kept in 1974.  People reported feeling it as far away as Pennsylvania and West Virginia, and the Web site of the United States Geological Survey stated that because of geological conditions East of the Rocky Mountains, quakes can be felt over areas up to ten times larger than on the West Coast.  Still, reasserting his now well-known inability to connect with the pulse of Aerica, President Obama said he didn't feel it.
