Well, if there's no indication of a tsunami, nor an earthquake in the
oceanbottom; how is the phenomenon Roger described and started this thread
to be explained? Or is it just imagination?

I still think it's a long wavelelength swell, which weather system created
it is open to debate.

Yes, I'd agree with that as the only possible explanation. Such swell can
travel vast distances and retain the most important wave features. Swell
waves become very smooth and regular, and lack the irregularities seen in
waves nearer the generating zone. Knowing their frequency/time period
might help confirm that idea.
