Yeah, it’s east of the Bahamas and North of Puerto Rico.

It’s a DART (Tsunami detection buoy).

Shows some sharp oscillations in water height in the last three hours.

No notable earthquakes near it, though.

Most likely some sort of malfunction; if not the (remote) possibilities are a tsunami induced by an underwater landslide; I think an asteroid would have been noticed.

The Puerto Rican trench is between Puerto Rico and this bouy. And this could be something like a SOLITON ~ not just a rogue wave, but a really big one that has coherency ~ think of it as a Laser phenomenon in a column of water.

Now that'd ring some bells!

Weird, I just went out on the deck a few minutes ago and noticed the water was white-capping at night, with no noticable wind - trees are still.

Maybe a Cloverfield event.
