Scientists with the Washington State Department of … I remember about 5 or 6 years ago we got hit with a 4.9 in our area and our home shook BIG TIME!! This page contains a collection of these resources and a brief description of each item. For example, the simulations show what would happen to the Long Beach Peninsula. "The warm colors in the simulation, the deep waves are high tsunami waves of 10 feet or greater," Allen said. Simulated Cascadia Tsunami Event Pass it on another day of Martial Law training? More information about these simulations on the DNR’s website and KGW. They covered the Tsunami very well. “Tsunamis have struck Washington’s coast many times over our geologic history,” said Commissioner of Public Lands Hilary Franz. To aid tsunami hazard mitigation, we used the 15 Cascadia tsunami simulations to map tsunami inundation. This hypothetical Cascadia tsunami is assumed to be generated by a Mw 9.0 earthquake off the Pacific Northwest Coast of the U.S. New Cascadia subduction zone earthquake study 'is worse news for Portland northward to Seattle' Updated Jan 29, 2019; Posted Jul 27, 2018 A seismograph at Portland State … In the simulation, areas that get hit hardest in Puget Sound are highlighted in red. In approximately 15 minutes, the tsunami would be first recorded at tsunameter/DART® buoys 46404, 46407, 46411 and 46419. Priest, C. Goldfinger, L.L. The department released a series of tsunami simulation videos that show the estimated height and speed of waves that would strike the southwest Washington coast following a magnitude 9.0 earthquake on the Cascadia subduction zone. eral Industries (DOGAMI) tsunami inundation maps (TIM series). The new simulations focus on the Cascadia Subduction Zone. Obviously they believe anything North of Bellingham isn’t going to be in any trouble or they just don’t matter. Frequency (depending on the source of the tsunami) and Amplitude (shape of ocean floor, shoreline and up-slope factors). You have entered an incorrect email address! The graphics display research model results, showing qualitative and quantitative information about the tsunami, including tsunami wave interaction with ocean floor bathymetric features, and neighboring coastlines. The DNR said these simulations are designed to give emergency planners and communities the best possible visualized information about tsunami impacts and timing so they can plan accordingly. Also remember the magnitude 9.0 EQ will shatter and destroy many buildings and homes before the tsunami hits!! “The first wave reaches the outer coast in about 15-20 minutes depending on where you are and it quickly travels inland over land through the bays up the Columbia River,” said Corina Allen, chief hazards geologist with DNR. Mohsen BC, People are hungry for truth news info Only at Steve quayle, Strange sounds, and Jason A, Stan deyo, top 10 only. The Really Big One: The Next Rupture of the Cascadia Subduction Zone Will Spell the Worst Natural Disaster in the History of North America. They show that a large earthquake could send waves up to 20 feet high onshore. Locally, Tacoma's Commencement Bay and the southern ends of Vashon and Maury islands get hit … The hydrodynamic computer model SELFE is used to simulate tsunami generation, propagation and maxi-mum inundation for five Cascadia subduction zone (CSZ) earthquake sources (SM1, M1, L1, XL1, XXL1) and two M w (moment magnitude) 9.2 Alaska earthquake sources: the Allen said the waves would move up the Columbia River, but nothing more than a strong current would make it all the way to Portland. Less than 20 minutes after the earthquake started, the first wave would hit Long Beach. The DNR wants Washingtonians to be able to visualize what another tsunami could do to the state. Animation of tsunami inundation in Newport, Oregon simulation from the ADCIRC finite element model. And the waves would keep coming. On Jan. 26, 1700, an earthquake with an estimated magnitude of 9.0 struck the fault, causing the coastline to drop several feet and producing a tsunami that crashed onto land, leaving sand deposits and drowned forests. Pacific Marine Environmental Laboratory | NOAA Center for Tsunami Research Get out of big cities now while you can or it will come a time all cities in the world already are center of storms. TIM series inundation maps incorporate all the best tsunami science that is available today, including recent publications by colleagues studying the Cascadia Subduction Zone, updated computer simulation models using high-resolution lidar topographic data, and knowledge gained from the 2004 Sumatra, 2010 Chile, and 2011 Tōhoku earthquakes and tsunamis. The videos show Cascadia tsunami wave simulations for the entire Washington coast, as well as localized views for Bellingham and the San Juan Islands. According to the DNR videos, the first waves would reach the outer coast approximately 15 minutes after the earthquake. NOAA Public Affairs Monica Allen - 301-734-1123 Live riots in USA 904-2020 Disclaimer always apply. Tsunami model amplitude information is shown color-coded according to the scale bar. Follow Strange Sounds to discover amazing, weird and unexpected phenomena around the world. Followed by dilymail in UK. (2011). The videos represent a tsunami that might occur following a Cascadia subduction zone magnitude 9.0 earthquake. Learn how your comment data is processed. Inundation exceedance lines delineate the likelihood (in percent) that Cascadia tsunamis will exceed the simulated inundation ( … OLYMPIA, Wash. (AP) — New videos show how large tsunami waves are likely to impact the coast of Washington state. Iceland earthquake swarm and signs of inflation: Is Thorbjörn, Fagradalsfjall or Krysuvik going to blow? Here some videos for Washington’s regions along the Cascadia Subduction Zone: You will find a great documentary about the Cascade volcanoes rising like giants from the Earth in this part of the US by clicking on the image below: Tsunamis have hit Washington in the past, and they will happen again in the future. The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700 with an estimated moment magnitude of 8.7–9.2. Disclaimer: The model simulations on these pages show the results of ongoing research to enhance tsunami science and to improve NOAA operational tsunami forecasts. They should not be used as the basis of any public or private policy decisions. 3 powerful M7.3, M7.4 and M6.1 earthquakes hit New Zealand and Vanuatu within 4 hours, Scientists have discovered a new active fault line capable of a M6.9 earthquake in California… And it runs just under San Diego (video). ??

Trinity Quakes: 3 strong M6.1 earthquakes hit the Royalty Islands, Vanuatu and Wallis and Futuna in 14 hours… Signs or simply coincidence? Truth shall make us set free. A powerful earthquake thought to be as large as 9.2 magnitude ripped through the earth in 1700, along the 620 mile stretch of the Cascadia Subduction Zone, causing severe shaking and … Each video is sped up 300 times in order to show the spread of the tsunami over a period of several hours. Geologists at DNR, home to the Washington Geological Survey, produced the simulations using detailed tsunami models. Toward the end of this simulated 48 hours of activity, the wave animation will transition to the "energy map" of a mathematical surface representing the maximum rise in sea level on the open ocean caused by the tsunami, a pattern that indicates that the kinetic energy of the tsunami was not distributed evenly across the oceans but instead forms a highly directional "beam" such that the tsunami was far more … 320 years since Cascadia last quaked. A tsunami that reaches a height of 300 feet when it rears up at the shore, will lose energy as it travels inland. https://www.youtube.com/watch?v=FIpcQQC6jaU Be curious! I already predicted more blood shed coming and the PDX is in hell. NWS Public Affairs Susan Buchanan - 301-713-0622, National Oceanic and Atmospheric Administration There is an estimated 2-4 minutes of shaking or rolling that will be felt along the coast line with the strength and intensity decreasing the further inland you are. 1999). A color-coded computer simulation from 2016 shows how researchers think tsunami waves propagated from a magnitude-9 Cascadia subduction zone earthquake in the year 1700.
