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 and New York City.
The quake sent hundreds of people spilling into the street a block from the White House, with other buildings evacuated in North Carolina and tremors felt as far away as New York City.
The U.S. Geological Survey said the earthquake was 3.7 miles 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. The quake was in Mineral, Va., in Louisa County.
The earthquake was also felt at the US Open grounds, where qualifying play got underway on Tuesday.
Several players tweeted about feeling the effects of the earthquake.
