All the coverage on the 50th anniversary of the 64 quake has been interesting. The wave heights quoted in one of the ADN articles indicates that Passage Canal had a 104' wave, Blackstone hit 79', Valdez 30' and other places had waves from 4' (Juneau) to 220' (Shoup Bay). The link is here: http://www.adn.com/2014/03/24/339158...-tsunamis.html
So, given the range of possibilities, what are the best strategies in the event of a tsunami warning?
Getting to deep water, if possible, would seem best - but how deep does the water need to be and far from shore does one need to be for safety? Is Port Wells enough? It is hard to tell, but from the listings even some fairly open areas of water got hammered with big waves - Port Nellie Juan for instance.
Common sense says that the amount of time you have, and the distance to deep, open, bodies of water, will be the important factors, but how deep an how open?
This is an issue that crosses my mind every time I am out, particularly with the family.
So, a fer instance: You and the family are dead asleep in Deep Water Cove, a warning comes over channel 16, you have a marginal amount of time to make it open water between Perry and Main Bay. How do you decide weather to scramble up the mountain and be stranded without your boat, or make a run for it?
In doing the analysis, how do you figure out how deep "safe" water is and how far out into open water you need to be for safety?
Any insights will be appreciated!!
