It's been standard knowledge as far back as I can remember. It was what
was expected in Hawaii in the 50's in those tsunami warnings. (Note back
then they were called tidal waves, not sure exactly when tsunami took
over as the name).

My only point is that in my experience if you depend only on that as
your early warning, you may have no warning at all.

I've certainly read of plenty of cases where it did apply as well.
