A 5.9 magnitude earthquake originating in Virginia rocked Washington, D.C. on Tuesday shortly before 2 p.m. EST, and seems to have been felt as far north as Quebec City. Parts of the White House, the Pentagon and the Capitol Building have been evacuated, as well as the control towers at Kennedy International Airport and Newark Liberty International Airport, several sources report. The epicentre of the quake, which the U.S. Geological Survey said was 3.7 miles deep, was in Mineral, Virginia. Tuesday’s quake was the second strong shake to hit the U.S. since Monday night, when many Colorado residents awoke to trembling shelves and furniture due to a 5.3 magnitude tremor, the largest to strike the state in 40 years. No injuries have been reported so far in either quake, although buildings on Tuesday were being evacuated as far up north as Toronto.
