We learned during our endeavor to move Aminishi to Waiko that Moai die when they lose connection to an island's soil and will rapidly leak the anima and energy stored within them. This certainly appears to be what's happening to the Moai on the uncharted isles.
But how can that be the case, they are clearly on islands. To that, I question if they really are. The uncharted isles are a fairly interesting place. No matter how exploratory voyages you go on, you're never able to find an island you've already visited unless you mark the island with a special flag. Furthermore should one lobby or log out while on an uncharted isle, they'll be greeted with a message that explains how any items left on the floor have washed out to sea no matter how far inland/high up.
This leads me to a conclusion. The uncharted islands are much more sandbars than they are actual islands. They likely submerge, shift, and reemerge quite often, with only the island claiming flags and/or the presence of sentient life acting to stabilize an isle.
