A Dive Instructor at Cobalt Coast Reef Divers on Grand Cayman was diving Sandhole when the quake struck yesterday, here is his account of the frightening experience. The article also mentions that lots of jellyfish washed up on the beach after the quake.

"...Lee Bush, a dive instructor and boat captain at Reef Divers, was 40 feet underwater when he experienced his first earthquake in Cayman. He and three other divers were at Sandhole Reef when it struck.

“It felt very much like a boat that was coming close to you because when you’re underwater you can hear boats and the noise was getting louder to the point where we almost thought the boat was on top of you,” he said. “But, obviously, it wasn’t, because there wasn’t a boat, but it was just very unnatural, very unnerving. At this point, you can feel your heart beating almost out of your chest.”
Lee Bush said the rumble he felt go through his body built up for about 25 seconds.
“It started off really slowly, it’s like a great crescendo. At that point, all the fish from the top of the reef just came straight off the wall and down, and just behind that, it looked like all the sand was coming off as well,” he said.
He added that the visibility in front of him went from about 100 feet to just three or four feet.
“It looked like fog rolling over mountains, the sand just came through everything and then it just literally covered everything,” he said. “In 10 years of diving, I’ve never experienced anything like that whatsoever. Never seen fish behaviour like that, never seen the way the sand moved like that, and never felt that real deep rumble before.”

And here's an article about the Cayman Sister Islands during the Earthquake, apparently their last large quake was in 2004. It includes a report from another diver that was underwater when it struck and she also thought that it was a boat "the biggest boat ever" coming at them. They dived down to try and avoid the boat and she felt pressure in her ears and couldn't clear.
At least Brac has high ground if they ever get hit with a Tsunami (hopefully not!) but Grand Cayman and Little Cayman are pretty flat.
