Courtesy USGSI got a text from my oldest son today that read: "Just felt my first earthquake." What's weird is my son lives in Brooklyn, NY. It's probably the last text message I'd ever expect to get from him. But there was indeed an earthquake on the East Coast this afternoon, a rather large one, in fact. The magnitude 5.8 trembler was centered in Virginia and could be felt as far north as New England and as far south as Georgia. A nuclear plan near the epicenter was shut down, as were some government buildings in Washington, DC. Callan Bentley, an associate professor of geology at Northern Virginia Community College who blogs on the American Geophysical Union's Blogosphere website, has posted some excellent information about it here.
