Atwater and Moore [1992] have interpreted sandlayers found at West Point and Cultus Bay as tsunami deposits. The tsunamis are generated as a result of A tsunami will take a long time to work its way through the sound, and we're very far from Hawaii, so I expect there would be four to five hours of warning time. This project aims to simulate and map the tsunami hazards within Puget Sound communities which might be A recent unpublished simulation by the Pacific Marine Environmental Laboratory, NOAA, of a Cascadia tsunami propagating into Puget Sound predicts maximum water levels of over 4 m for some high water "hot spots" at the heads of narrow waterways. VS=Vashon, TC=Tacoma. On NW coast, potential for tsunami waves up to 100 feet now seems possible. The inundation map of the Seattle waterfront area shows that the heavy inundation occurs at Pier 90, 91 Luckily, many of the areas that will be hit hardest are not very residential, like Sodo in Seattle. For the modeling of tsunamis, we use the digital elevation data provided by PRISM Considering the above interpretations, we assume a M7.2 earthquake on the Seattle Fault which covers an local seismic uplift generates 1.5 m tsunami at the moment of the earthquake, then the water is receded.
