As part of a tsunami hazard mapping project funded by the National Tsunami Hazard Mitigation Program, the NOAA Center for Tsunami Research (formerly known as the NOAA Center for Tsunami Inundation Mapping Efforts) modeled tsunami inundation for the at-risk coastal community of Tacoma, Washington. Three tsunamigenic moment magnitude 7.3 earthquake source scenarios within the lower Puget Sound region were investigated: one along the Seattle Fault, and two along the Tacoma fault based on the most recent geophysical evidence. A high-resolution tsunami model was applied to estimate tsunami propagation in the southern Puget Sound region and inundation along the greater Tacoma area. These model results (Appendix A) were provided to the State of Washington for use in tsunami hazard maps to assist in the design of evacuation plans for the at-risk study area.
