NEW YORK - A 5.8 magnitude earthquake sent tremors from Washington to New York City Tuesday afternoon, but there were no reports of damage. It is not clear how far the earthquake spread, but tremors were felt throughout New York City office buildings and as far north as Concord, New Hampshire. The streets of downtown Washington filled with thousands of people as buildings from the Capitol to the White House were evacuated. Fire alarms sounded throughout the downtown business district in Washington on an otherwise bright and sunny afternoon.
