WASHINGTON (AP) - A 5.8 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 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 shaking was felt as far north as the Martha's Vineyard, Mass., golf course where President Barack Obama was just starting a round.
The geological agency says the earthquake, which struck at 1:51 p.m., was half a mile deep and was centered near Louisa, Va.
The East Coast gets earthquakes, but usually smaller ones and is less prepared than California or Alaska for shaking.
At Reagan National Airport outside Washington, ceiling tiles fell during a few seconds of shaking. Authorities announced it was an earthquake and all flights were put on hold.
A magnitude 5.3 earthquake hit southern Colorado earlier today. It is the strongest quake to hit Colorado in almost 40 years.
The quake overnight shook hundreds of people awake, knocked groceries off shelves and caused minor damage to homes in the southern part of the state and in northern New Mexico. But no injuries are reported.
