Yesterday's relatively exciting magnitude 5.8 East coast quake didn't tilt D.C.'s Washington Monument, but it cracked it enough to concern the National Park Service. So a centerpiece of the National Mall will now be closed indefinitely for public safety reasons, the Associated Press reported. The damage was found by structural engineers "where the 555-foot landmark narrows considerably." The Lincoln and Jefferson memorials are also closed for further inspection, Politico relayed. The newly unveiled Martin Luther King Jr. sculpture will remain open. And the rest of the nation's capitol dwellers will talk about where they were during quake for the forseeable future--or at least until Congress is back in session.
