10. Rafts of floating pumice-locally thick enough to support men, trees, and no doubt other biological passengers-crossed the Indian Ocean in 10 months. Others reached Melanesia, and were still afloat two years after the eruption.

This is interesting as a method of spreading "local" species around. It wouldn't happen often, but apparently it does happen.

One problem with the pumice raft. You don't want to catch it at the launch point.

Re #12

Yeah, that is an interesting way to look at it. I came across no one who mentioned it as a means to spread species.
