There are a lot of things to worry about when you're passagemaking offshore. And, its quite possible that if you sail for a few hundred years and spend a lot of time in port a tsunami might be one of those worries. However, the press not withstanding, the chances of a passagemaker being effected by a tsunami is practically non-existent. The statistical probability of damage is extremely low. If you are at sea, a tsunami's manifestation in the open ocean is limited to a few inches of wave amplitude. If you are in port, you have to be in very shallow water. Most yachts in the effected areas were not damaged or experienced a brief wave bounce. A client of mine with a tourist submarine in Thailand was completely unaffected as were all his support boats. I mean really, has anyone on this forum ever encountered a tsunami event that has caused damaged to their vessel, or, even heard of one for that matter. Bad luck can plague anyone but I certainly wouldn't lose any sleep over the lack of a single point receivable tsunami early warning system. There's a lot more important issues to lose sleep over other than an event that happens in a localized area every 100+ years. -- ======================================================================= L.

I forgot to post a follow on to this. I would assume from your 208 area code that you don't live down on the coast. I have and have seen several Tsunami events. None of consequence in real time, but plenty of damage from the Alaska Quake of 64', afterwards. Warnings are a regular occurrence on the west coast. I have been going in and out of Crescent City CA for many years; one place where there was a lot of damage. If you haven't seen such damage for real, then you may be more inclined to dismiss it. Under the circumstances, I take it seriously. One of the factors which has just become obvious is that rather than the PNW having a 9.0 quake at some point location, the scientists are making the argument that the entire Cascadia Subduction Zone could shift along it's entire 750 mile front and take the adjacent land with a serious Tsunami Wave. That is roughly what happened in Aceh Province in Indonesia. Now that is something to be concerned with, since it has been 300 years since the last similar one here and there is some indication that the ruptures have been occurring about every 300-500 years.
