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. 1999). This event's primary features are a rupture length of approximately 1050 km, average rupture width of 70 km, and slip of 17.5 m. More information is available in Venturato et al., 2004.

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.

Seattle Fault Earthquake

These animations are based on a simulated magnitude (Mw) 7.3 earthquake along the Seattle Fault.  Details on the fault parameters and subsequent analysis at Seattle and Tacoma, Washington, are available in Titov et al., 2003 and Venturato et al., 2007, respectively.

Tacoma Fault Earthquake

These animations depict two possible earthquake scenarios along the Tacoma Fault.  The first scenario considers a magnitude (Mw) 7.3 earthquake based on published fault traces from Johnson et al., 2004 extending from Case Inlet eastward through Dumas Bay.  The second scenario considers a magnitude (Mw) 7.3 earthquake based on an inferred wedge tip along the Rosedale monocline described in Brocher et al., 2004.  Details on the fault parameters for these scenarios are available in Venturato et al., 2007.

San Juan Islands, WA

These animations show the impact on the San Juan Islands, WA of a tsunami generated by a Mw 9.0 subduction zone event along the Cascadia margin. The scenario modeled corresponds to the L1 source in Witter et al., (2011) and is associated with a full margin rupture, an average slip of 13 m and a max slip of 27 m.

Details on the modeling are available in Arcas et al. (2020).
