The Nisqually Earthquake of February 28, 2001, which shook Western Washington and beyond, seriously damaged or destroyed some buildings, along with roads, and impacted bridges. At 10:54 a.m. on February 28, 2001, a deep earthquake centered near the Nisqually Delta northwest of Olympia startles the entire Puget Sound region and causes more than $1 billion in damage to area buildings and roads. One person died of a heart attack, hundreds were injured, and various estimates place damage at between $500 million and $4 billion. The PNSN plans to monitor the MLS Cup Finals in Seattle on Sunday, Nov 10, 2019. This location is near the For many communities, two types of macroseismic intensity are assigned, the traditional U.S. Geological Survey Modified Mercalli Intensities (USGS MMI) and a type of intensity newly introduced with this paper, the USGS Reviewed … The intraslab earthquake had a moment magnitude of 6.8 M W and a maximum Mercalli intensity of VIII (Severe).The epicenter was in the southern Puget Sound, northeast of Olympia, but the shock was felt in Oregon, Canada, eastern Washington, and Idaho. If you were in Western Washington on Feb. 28, 2001, chances are you remember what you were doing that morning. The colors indicate the magnitude of the vector formed by the two horizontal components of ground velocity from the simulation. The February 28, 2001, Nisqually, Washington, earthquake (M w = 6.8) damaged an area of the northwestern United States that previously experienced two major historical earthquakes, in 1949 and in 1965. Date: Feb. 28, 2001 Epicenter: Anderson Island, about 10 miles from Olympia Depth: 53 kilometers, or about 32 miles Damage: Estimates from $500 million to more than $2 billion Injuries: 300-400 Deaths: One indirectly attributed to the earthquake. A decade ago, scientists knew Western Washington was vulnerable to much nastier shakes than the magnitude 6.8 that rattled Seattle on Feb. 28, 2001. The preliminary location by the University of Washington Seismological Laboratory places the earthquake at a depth of 52 km with an epicentral location of 47.149 °N and 122.727 °W. At 10:54 a.m., there was a magnitude 6.8 earthquake … The 2001 Nisqually earthquake occurred at 10:54:32 local time on February 28, 2001. This is an animation in map view of the ground motions from the 3D finite-difference simulation of the 2001 M6.8 Nisqually earthquake. We present isoseismal maps, macroseismic intensities, and community summaries of damage for the MW=6.8 Nisqually, Washington, earthquake of 28 February, 2001.
On Wednesday, 28 February 2001, a moment magnitude 6.8 earthquake occurred beneath the southern Puget Sound area of Washington State. What is a Spectrogram? Nisqually Earthquake – Quick Facts. Time after the origin time is indicated in the lower left hand corner. 1.8 magnitude earthquake 2020-05-08 22:57:26 UTC at 22:57 May 08, 2020 UTC Location: Epicenter at 46.557, -121.448 55.2 km from Tieton (34.2 miles)
The Nisqually earthquake on February 28, 2001, was a deep, magnitude 6.8 earthquake 10 miles northeast of Olympia. Event Name: Nisqually, Washington Earthquake Event Date: 02/28/2001, 18:54 UTC, (10:54 AM PST) Event Identification: 20010228_1 Recorder Type: ETNA, K2, MT WHITNEY, SMA-1 Preliminary estimates of direct monetary losses from damage due to earthquake-induced landslides is approximately $34.3 million.
