Nutty, nutty, nutty.......
......but I would like someone to explain that whirlpool...it really does look like the big bathtub being drained into Hades.
That's what happens when the entire town flushes at the same time! I think I remember being warned about that one time when I was a kid!!!!
My wife had an interesting theory. If you suddenly pop up the North American plate, you might get a cavity or two below that water could drain into. The other theory is that the crutal motion that produced the tsunami also created large turbulence with crosscurrents, not unlike tornado formation, hence a funnel. I like the cavity theory because it’s scarier, but the turbulence theory is probably correct.

It's called cropping a photo so that you can't see the structures causing an eddy to form.
Actually the whirlpool is easy to explain.
First, find a larger area picture of the whirlpool - they seem to be purposely cropped to make look like open sea...
There’s a sea wall near this forming a harbor (or protected water area) with an opening on one end to the open sea. When the tsunami water went rushing by the open end it spun the water in the harbor forming a whirlpool.
Look again. The surface of the water is calm except for some foam. That’s basically two minor currents missing mixing together.
