Security keeps people from entering the Lincoln Memorial in Washington, Tuesday, Aug. 23, 2011, after it was evacuated following an earthquake in the Washington area. A 5.9 magnitude earthquake centered in Virginia forced evacuations of all the monuments on the National Mall in Washington and rattled nerves from Georgia to Martha&#39;s Vineyard, the Massachusetts island where President Barack Obama is vacationing. No injuries were immediately reported. (AP Photo/Jacquelyn Martin)
