All the talk of moving the island got me thinking about an island I remember hearing about (a fictional one - maybe lol) which was able to move around and so avoid being discovered. I had a quick look to see if I could find it on the net and found this instead on wikipedia.

"Laputa is a fictional place from the book Gulliver's Travels by Jonathan Swift.
Laputa is a fictional flying island or rock with an adamantine base, that can be maneuvered by its inhabitants in any direction using magnetic levitation."

Maybe could explain how the island is able to be 'moved' given its extraordinary magnetic properties.

p.s I think it was Delos in Greek mythology I was thinking of.
