Abstract
Several locally generated tsunamis have been reported in Southern California during the past 200 years, yet the hazard from locally generated tsunamis has received considerably little attention. We consider here tsunamis generated by coseismic displacements on the Channel Islands Thrust (CIT) system, as well as waves generated by slope failures along the walls of the Santa Barbara Channel. We find that purely tectonic sources could generate regional tsunamis with ≈ 2mrunup, whereas combinations of tectonic sources and submarine mass movements could generate local runup as large as ≈ 15m.Keywords
