Tsunami Simulations for California

The following tsunami simulations were developed for the new state tsunami inundation mapping project by the Tsunami Research Center at the University of Southern California (TRC-USC; weblink:  http://www.usc.edu/dept/tsunamis).    These simulations have not been scaled, and do not  directly represent the location of the final inundation line displayed on the state maps.  The TRC-USC should be credited when referencing these simulations.


Stop-motion image of a simulated tsunami generated by a full-scale fault rupture of the Cascadia Subduction Zone.  The tsunami moves west across the Pacific Ocean, and east towards the coast of California, Oregon, Washington, and British Columbia.  Note the location of the tsunami simulations for the regional area (northern California; rectangle B) and the local area (Orick, California; rectangle C).


















Tsunami simulation for Crescent City from a repeat of the 1964 Alaska Earthquake (1964_cresc2.mov).

Four tsunami simulations (full scale: CSZ-L_north_wide.mov; regional: CSZ-L_norcal_b.mov; Orick local: CSZ-L_norcal_orick; and Crescent City local: CSZ-L_norcal_cres.mov) for the north coast of California from a large Cascadia Subduction Zone earthquake.  Note that the first wave is not the largest, and that inundation for this event in Crescent City would be about twice as much as a repeat of the 1964 event.
