The tsunami moves west across the Pacific Ocean, and east towards the coast of California, Oregon, Washington, and British Columbia. Cascadia Subduction Zone Earthquake: Eastern Strait of Juan de Fuca The earthquake scenario depicted in these animations is a magnitude (Mw) 9.1 Cascadia Subduction Zone event (Priest et al., 1997 and Myers et al. Oregon is unprepared for the tsunami that could follow a Cascadia Subduction Zone earthquake. Tsunami hazard assessment in Oregon has proceeded by first completing a de- tailed inundation simulation of the Siletz Bay area where various model parameters were tested against estimates of inundation and run-up from prehistoric tsunami deposits. Oregon State University The Florence, Oregon Forecast Model Grids provides bathymetric data strictly for tsunami inundation modeling with the Method of Splitting Tsunami (MOST) model. "While you might be able to get to your vehicle and start driving, you don't know what you'll encounter in road infrastructure and traffic conditions ahead of you,” he said. MOST is a suite of numerical simulation codes capable of simulating three processes of tsunami evolution: generation, transoceanic propagation, and inundation of dry land. Sometimes the shortest route is not necessarily the safest. And although many people fleeing a tsunami will turn to vehicles for evacuation, Wang said that using a car or truck is not a fail-safe solution, because damage to roads and bridges caused by the earthquake that precedes a tsunami can cause traffic problems and create chaos. Control rotation, wave speed, choose various famous quake presets. Such deposits are being used to identify past tsunami events and thereby better constrain estimates of both earthquake and tsunami hazard. These virtual people follow several evacuation routes that lead away from the beach toward safe zones on higher ground. structure Simulation and Analysis Center Homeland Infrastructure Threat and Risk Analysis Center (HITRAC) within the DHS Of-fice of Infrastructure Protection, provides a primary foundation for estimating the impacts of a Casca-dia Subduction Zone earthquake. The new article was prompted by passage of HB 3309, the new Oregon law that once again allows building “new public facilities” in the state’s tsunami-inundation zone. Asteroid Size. 3, 321-332. This digital data release is for seven tsunami inundation scenarios for the entire Oregon coast in the form of polygons (Esri ArcGIS® shapefiles). New tsunami simulations indicate that the largest waves may run up to elevations twice as high as earlier models predicted and flooding may inundate hundreds of yards farther up coastal valleys. Cox is part of an Oregon State cross-disciplinary research team that is developing a computer tool to model various evacuation scenarios. Newport, Oregon. ... That's the crest of the tsunami.
