Office workers and others gather on Free
Office workers and others gather on Freedom Plaza after an earthquake struck Washington, DC August 23, 2011. One of the strongest earthquakes to strike the US east coast in decades rattled offices Tuesday in downtown Washington and caused panicked evacuations from skyscrapers as far away as New York. The Pentagon, the US Capitol and Union Station in the nation's capital were all evacuated after the 5.9-magnitude quake, which was shallow with its epicenter only 0.6 miles (one kilometer) underground.The disruption to cell phone services in the hour after the quake added to the sense of panic in a country preparing to mark the 10th anniversary of the September 11, 2001 terror attacks.
