I tend to agree with Doug. Cities in Washington and Oregon are probably at considerably more risk. Not only do they have the risk from an Alaskan tsunami, but also from the fault lines off the coast of Oregon as well (generating a local tsunami from the ocean along the Oregon coastline). In California, the place that normally sees real problems is Crescent City - due to the unusual way that incoming waves are amplified (in height) when they come into the bay there.

But there's no doubt that So. Cal could suffer some expensive damage. I think it's likely that we are going to see some pretty serious activity - seismic or tsunami. And quite probably in our own lifetimes. But was we've said many times - no-one can tell when.

cheers,
