 The largest historical tsunami from far away to hit Santa Cruz is the 1946 Aleutian earthquake, produced very huge tsunami locally as much as a hundred meters high. Big tsunami, 17 meters high in Hawaii in Hilo, but locally and not many people remember those. It actually produced about a four to five meter high tsunami that swept in the boardwalk. It's responsible for the one loss of life from a tsunami in Santa Cruz. A man was killed on Cal Beach by that wave. So and that was a remote tsunami, but comparable size tsunami could be produced by landslides along Big Sur.
