The NOAA Center for Tsunami Research modeled tsunami inundation from a great Cascadia Subduction Zone earthquake for the coastal communities of Long Beach and Ocean Shores, Washington. A high-resolution numerical model was used to estimate tsunami propagation and inundation along the outer coast of southwest Washington.
The tsunami source is based on prior work by Walsh et al., (2000) that simulates a great Mw 9.1 earthquake with an asperity off the coast of northern Washington. Details of this scenario and the model results are provided in Venturato et al., 2007. These animations depict wave propagation and inundation at each location.
