Now, an island was considered in having permanent characteristics but see this article
(Washington, DC) Unusual images of the Earth have occasionally been uncovered after declassification of hundreds of thousands of spy satellite images by the National Imagery Mapping Agency (NIMA). In one of the more spectaular images, gathered on May 25, 2005, the apparent levitation of at least two Caribbean islands above the surface of the ocean was captured (above).

The islands are located in a large region popularly known as the Bermuda Triangle. The spy satellite imagery clearly shows shadows cast by two of the islands on the ocean surface in such a way that can only be explained if the islands are levitated above the ocean surface, in one case by approximately ten miles
So if it can levitate, it can do whatever is needed.
