When I saw “hydrothermal field”, I immediately thought mid-Atlantic ridge. But this is OFF Cuba, so is there really a hydrothermal field close of Cuba? At over 600 meters, this is very deep. However, we do have the history of the serious sinking of Port Royal caused by a severe earthquake several centuries ago. However, that was less than 100 feet. On the other hand it was only centuries ago, not millennia ago.
I have visited several very old Central American and Mexican urban ruined cities. Some well restored, or perhaps not even that ruined, and my impulse is to say these photos, if not manufactured, “feel” like ancient remains to me. Of course this is not scientific findings, just my gut. ;-)

Looking at these photos it could not be mistaken for anything but man made structures. But the photos are a computer generated artist’s rendering. I remember the first images they shared of the actual Sonar signatures. It would be stretch to call them man made from the actual original sonar sources. These photos here are a misrepresentation for sure...
