Smart move mate.
I was only six or seven at that time, in Cambria (near Hearst Castle) in California. I remember so well seeing all the pick-ups crammed with belongings and kids, and being driven to higher ground. My family and I lived literally across the street from the ocean, but it wasn't beach, it was cliffs and tidepools, and thus it would have to have been a mighty large surge to have reached us. I remember my brothers and me lounging over the fence "waiting" for the tidal wave, and one of my brothers jokingly raising his arms protectively over his head, as if to protect himself from something crashing down on him.
Nothing of much significance happened in our part of Cambria, but down the coast in Morro Bay, the tidal wave (more like a big surge, I think) tore up some docks pretty good. Ah, the memories!
