“Herds of animals” do not “migrate” before a tsunami comes, and they did not do it this time. They were simply less likely to be on the populated coast, more agile in avoiding the water and the story sounds too cool to not report it despite its minimal truth factor.
And BTW, if this tsunami passed under our aircraft carrier battle groups at sea it wouldn’t have been noticed. And all ports capable of berthing them are sheltered.
In Japan I have seen cockroaches swarming just before a major earthquake. This is an effect worth investigating, but it's hardly something you would want to base a warning system on. In any case, the effects of a tsunami extend far beyond the affected radius of the earthquake that caused it.
True.
And all ports capable of berthing them are sheltered.
I'm not sure what your definition of "berth" is. I've been to Phuket before, anchored less than a mile off of Patong Beach, where the major damage was. The big deck amphib with us was further out, but not a whole lot. I don't know what would have happened if we had been there when a wave of this size went through. Dragging anchor and ending up grounded could be a real possibility.
Tell it all to someone who hasn't spent several months at sea in a carrier battle group and since then has as a Ph.D. scientist conducted and reviewed applications for research in infectious diseases and neurobiology (including animal behavior)....
