Nisqually Earthquake On February 28, 2001 at 10:54 a.m., the Capitol shook from the seismic power of the 6.8 magnitude Nisqually earthquake. This is an animation in map view of the ground motions from the 3D finite-difference simulation of the 2001 M6.8 Nisqually earthquake. The fact that a relatively mild earthquake can yield such significant losses may be the most important lesson Nisqually …
California’s 1994 Northridge earthquake had a similar moment magnitude (6.7 Mw) but was only 18 … Centered a mere 17.8 kilometers northeast of Olympia, at a depth of 52 kilometers, the earthquake caused considerable damage to the Legislative Building and surrounding structures. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram. The 2001 Nisqually earthquake was a large magnitude (6.8 Mw) quake that yielded relatively mild ground shaking. 2001 Nisqually earthquake. Centered a mere 17.8 kilometers northeast of Olympia, at a depth of 52 kilometers, the earthquake caused considerable damage to the Legislative Building and surrounding structures. At a focal depth of 27 km (17 mi), this great undersea earthquake measured 8.3 on the moment magnitude scale, making it the most powerful earthquake of 2003, as well as one of the most intense earthquakes to hit Japan since modern record-keeping began in 1900. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. In 1999, the moment magnitude 5.8 Satsop earthquake occurred within the subducting Juan de Fuca plate about 60 km to the west of the Nisqually earthquake. The biggest surprise about the Nisqually earthquake was that it wasn’t worse. Yet Northridge, which had a magnitude 6.7, was the costliest disaster in U.S. history with an economic loss of $40 billion. At 10:54 a.m., there was a magnitude 6.8 … The Nisqually earthquake caused many types of ground failure, … Produced by Michael B. Fearnehough. The 2001 Nisqually earthquake occurred at 10:54:32 local time on February 28, 2001. EFFECTS OF THE 2001 NISQUALLY EARTHQUAKE ON SMALL BUSINESSES IN WASHINGTON STATE Prepared for: ... past and potential earthquakes. The Nisqually Earthquake shook much of western Washington State on the morning of February 28, 2001, and caused widespread damage, much of which resulted from ground failure. There was more shaking in the Northridge earthquake because the earthquake occurred closer to the surface (3-11 miles), as opposed to the Nisqually earthquake's deeper hypocenter (30-36 miles). Documentary of impacts to the Seattle area following a 6.8 magnitude earthquake later named the Nisqually Earthquake. Nisqually Earthquake. Quite the same Wikipedia. On February 28, 2001 at 10:54 a.m., the Capitol shook from the seismic power of the 6.8 magnitude Nisqually earthquake. Magnitude is expressed in whole numbers and decimal fractions. 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. This report presents a description and tabulation of damage and monetary losses caused by earthquake-induced landslides resulting from the earthquake. April 29, 1965: A 6.5 magnitude, deep earthquake in the south Sound area was felt as far away as Montana and British Columbia, and knocked down thousands of chimneys in the Puget Sound. The Nisqually mainshock was followed by If you were in Western Washington on Feb. 28, 2001, chances are you remember what you were doing that morning. Nisqually is estimated to have caused approximately $305 million in insured losses, $2 billion in total damage, and one heart attack death. Yet it was the costliest natural disaster in Washington State history.
2001-02-28 18:54:32 (UTC) | 47.149°N 122.727°W | 51.8 km depth The ground shook for about 45 … Events deeper than 35 km are green. It was centered about 11 miles north of Olympia. Time after the origin time is indicated in the lower left hand corner. Image showing the location and depth of the Northridge and Nisqually earthquakes. The magnitude 6.8 quake brought down brick facades, damaged Seattle’s waterfront viaduct and split the Capitol dome in Olympia. Shallow events are black. The 6.8 magnitude Nisqually earthquake shook the Pacific Northwest on February 28, 2001 at 10:54 a.m. magnitude 6.5 Seattle earthquake occurred about 40 km northeast of the Nisqually earthquake and had a similar fault orientation as the 2001 event. Events deeper than 35 km are green. Just better.
The colors indicate the magnitude of the vector formed by the two horizontal components of ground velocity from the simulation. A map showing a closer view of the earthquake and prior historical earthquakes with magnitude 3.5 or greater. 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. 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.
