Came across this video and would love to see an underwater version. Looks crazy.
This is what a lake covered in volcanic ash looks like. [VIDEO]

I sure hope he was a smoker. After letting his reg drag around in that crap it had to taste kinda nasty.
Mmmm, pumice. Yummy!
I dove in Kadavu when the Tonga underwater volcano was erupting. The ocean was covered with 6" of pumice (not as bad as in that video). Backrolls into the water were interesting... The regs get full of pumice bits but it's easily blown out.
The pumice usually sits right on top of the water. It's bizarre when you're getting in and out, and it's terrible on the outboards. It also makes it like a night dive -- take a light.
What's really weird is that after a few days the pumice becomes water logged and some of it goes neutrally buoyant. So you end up diving through a miniature asteroid field, some of them with clams starting to grow on them.
Very fun.
