On the morning of February 28, 2001 the Pacific Northwest was hit by a 45 second, 6.8 magnitude intraslab earthquake called the Nisqually or “The Ash Wednesday” earthquake. The Nisqually earthquake occurred when the Juan de Fuca plate subducted under the North American plate, this quickly released the built up strain. This was caused by mineral changes as the plate moved farther into the mantle. The Nisqually earthquake hit the southern end of Puget Sound causing damage to the ports of Seattle and Tacoma. Most of the property damage occurred near the epicenter. For example, in Seattle, the Alaskan Viaduct and its seawall were extremely damaged. In Olympia the Fourth Avenue Bridge was damaged. Following the earthquake liquefaction, sand boils,

There have been efforts to build new buildings that are earthquake ready and to retrofit older buildings. Also there are plans to take down the Alaskan Way Viaduct that was damaged in the Nisqually Earthquake and build a tunnel instead. This event made people more aware of the importance of emergency preparedness. Soon after the earthquake occured, rapid response systems were improved in case there was another big earthquake. Most people now know what to do in an earthquake such as going under a table and shielding your …show more content…

After an earthquake has passed each group of engineers have an assigned district weather it be city or neighborhood to inspect buildings for damage and mark them red for do not enter, yellow for moderately damaged, and green for structure is not damaged but take caution entering… during the Nisqually earthquake these precautions went in to affect immediately after.
