Greater Seattle Area Rattled By Temblor

February 28, 2001 Nisqually, Washington Earthquake

The greater Seattle area was shaken by a magnitude 6.8 earthquake on February 28, 2001 at around 11:00am PST. The duration of the shaking was approximately 45 seconds, and the hypocenter of the quake was 52 km below ground, about 20 km northeast of Olympia, Washington. The earthquake was felt as far away as Salt Lake City, and the ground motions were also strongly felt in Oregon and British Columbia.

The depth of the temblor helped minimize catastrophic damage, although widespread damage to buildings, roads, and bridges was reported in the Olympia, Tacoma and Seattle regions. The earthquake resulted in over 400 injuries, with 4 of those being classified as "serious".
