The Nisqually Earthquake was a strong earthquake to hit Washington State in February 28, 2001. It was a 6.8 on the Richter Scale and its epicenter was near Olympia. It lasted for 45 seconds.
Seattle was hardest hit in and around Pioneer Square where most buildings are brick, which does not hold well in an earthquake. Parts of buildings there even fell crushing cars.
People in downtown's skyscrapers reported much swaying though little damage. Seattle's tallest building the Columbia Center for example only suffered one cracked window.
Many were injured, but luckily nobody died. There was a report of a cardiovascular condition during the quake which resulted in a death though.
