The Pentagon was evacuated after employees felt
WASHINGTON (AP) -- A 5.9 magnitude earthquake centered northwest of Richmond, Va., shook much of Washington, D.C., and was felt as far north as Rhode Island, New York City and Martha's Vineyard, Mass., where President Barack Obama is vacationing.
The U.S. Geological Survey said the earthquake was half a mile deep. Shaking was felt at the White House and all over the East Coast, as far south as Chapel Hill, N.C. Parts of the Pentagon, White House and Capitol were evacuated. There were no immediate reports of injuries.
It was centered near Louisa, Va., which is northwest of Richmond and south of Washington.
Obama and many of the nation's leaders were out of town on August vacation when the quake struck at 1:51 p.m. EDT. The shaking was felt on the Martha's Vineyard golf course as Obama was just starting a round.
The East Coast gets earthquakes, but usually smaller ones and is less prepared than California or Alaska for shaking.

In Ohio, where office buildings swayed in Columbus and Cincinnati and the press box at the Cleveland Indians' Progressive Field shook. At least one building near the Statehouse was evacuated in downtown Columbus.
