This is kinda necro-ish, but I was rereading the fic in question recently.
One big thing that they came up with in discussion there was the point that the fold took the island with.
So what was left under it?
Answer: It wasn't just water displacement, it was the massive underwater volcanic eruption caused by the fold suddenly ripping the cap off of the magma chamber under the island.
