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.

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.
