The National Park Service has discovered cracking in the stones at the top of the Washington Monument. The monument will be closed indefinitely, the AP reports.
Structural engineers will evaluate the cracks on Wednesday to determine the best way to repair the Monument before it is reopened.
The grounds have been reopened, save for an area about 100 feet outside of the plaza.
The earthquake forced evacuations of all the memorials and monuments on the National Mall and rattled nerves from South Carolina to Martha's Vineyard, the Massachusetts island where President Barack Obama is vacationing.
The Lincoln and Jefferson memorials were closed for a short time but then reopened. The Martin Luther King, Jr. Memorial, Franklin Delano Roosevelt Memorial, the World War II Memorial, Vietnam Memorial and the Korean War Memorial remained open.
Of course, the Washington Monument already has its own parody Twitter account.
