Pentagon evacuated as strong earthquake rattles Washington 23 Aug 2011 A strong earthquake measuring 5.9 struck the US east coast on Tuesday, rattling buildings in downtown Washington and causing evacuations of buildings as far away as New York. An earthquake of at least 5.9 magnitude and centred in southern Virginia shook much of the American east coast, being felt as far as Canada and prompting the evacuation of buildings in Washington and New York City. Parts of the White House, the US Capitol and the Pentagon were evacuated amid fears that Washington might be under terrorist attack. Flights at John F Kennedy International Airport in New York and Reagan National Airport in Washington were suspended.
