The good news is that residents in the Seattle-Tacoma area would have a long time to get out of the way.

This is because coastal areas have different beach slopes and different offshore and coastal geographical features, such as reefs, bays, and river mouths," the state DNR describes on its The state has mapped some tsunami areas in Puget Sound. >> >>

The Cascadia Subduction Zone (CSZ) is a 1,000 km (620 mi) long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California. /Producer (Adobe PDF Library 15.0) "These simulations really drive home how tsunami will impact all of Washington's coastlines," she said. In the simulation, areas that get hit hardest in Puget Sound are highlighted in red. The new state DNR simulations show how a tsunami would hit Washington in the event of a magnitude 9.0 earthquake along the Cascadia Subduction Zone. /Title <5473756E616D692048617A617264204D617073206F66207468652053616E204A75616E2049736C616E64732C2057617368696E67746F6E844D6F64656C20526573756C74732066726F6D20612043617363616469612053756264756374696F6E205A6F6E652045617274687175616B65205363656E6172696F>
New Juan de Fuca plate is created offshore along the Juan de Fuca Ridge..

<< Characterizations of tsunami hazards along the Cascadia subduction zone hinge on uncertainties in megathrust rupture models used for simulating tsunami inundation. New maps released by the state show a tsunami generated by a magnitude 9 earthquake on the Cascadia Subduction Zone would take 1.5 hours to reach the Anacortes and Bellingham areas.

The parts of the video in blue where water will fall below normal levels.

The simulation estimates that it would take about two hours for a wave to travel across the Salish Sea and down into central Puget Sound.

You can check this state map to And one more thing to remember: the SR 99 tunnel that replaced the Alaskan Way Viaduct has been built to withstand a magnitude 9.0 earthquake, /Author (Timothy J. Walsh, Edison Gica, Diego Arcas, Vasily V. Titov, and Daniel W. Eungard)

Locally, Tacoma's Commencement Bay and the southern ends of Vashon and Maury islands get hit with the worst of the waves, the simulation shows.But the simulation isn't necessarily meant to be an exact gauge of how bad the tsunami will be.

The new state DNR simulations show how a tsunami would hit Washington in the event of a magnitude 9.0 earthquake along the Cascadia Subduction Zone.

/Subtype /XML /ViewerPreferences << This week, geologists at the state Department of Natural Resources created a similarly scary video, although without all the death and destruction of the viaduct one. "A small nondestructive tsunami in one place may be very large and violent a few miles away.

The last major earthquake on the Cascadia subduction zone … Two hours after the quake, Bellingham Bay will empty, but 30 minutes later will get hit by a wall of water about 10 feet high, the video shows. tsunami hazard maps of the san juan islands, washington— model results from a cascadia subduction zone earthquake scenario by timothy j. walsh, edison gica, diego arcas, /Subject (Map Series 2016-01) That's according to a newly published Southwest Washington Tsunami Inundation Hazard Map. /Pages 6 0 R /Keywords (tsunami, inundation, earthquake, Cascadia Subduction zone, Washington, San Juan Islands) << /Type /Catalog /rgid (PB:310477769_AS:429819893686272@1479488456251) The worst of the tsunami … /Names 3 0 R 1 0 obj In estimating the tsunami hazards for the Pacific Northwest posed by major earthquakes along the Cascadia subduction zone, it is important to identify uncertainties associated with tsunami generation and their effect on near-shore tsunami amplitudes.

Corina Forson, DNR's chief hazards geologist, says the video is meant to give Washington residents a general idea of how one type of Cascadia Subduction Zone scenario would play out. Previous inundation mapping was based upon the last Cascadia Subduction Zone earthquake from 1700 AD.

After about 3-1/2 hours, Commencement Bay will empty as water rushes to inundate Stanwood on Camano Island. To explore these uncertainties, we constructed 15 megathrust earthquake scenarios using rupture models that supply the initial conditions for tsunami simulations at Bandon, Oregon. /ModDate (D:20161014112359-07'00') During those times, boats, commercial ships, and ferries could be in danger of getting stranded.

Luckily, many of the areas that will be hit hardest are not very residential, like Sodo in Seattle.
