Thank you so much for the information! I was in Home Depot today and their tile man told me there was no way tiles expand, so it had to be something that pushed through the subfloor. I was depressed all day thinking we had huge foundation problems, but I cheered up the minute I read your advice, Carey and Kapohocat. I will ask my tile man if he can remove some of the raised tile with a grinder and we'll have a good look at it. It was a common tile at Pacific Island Flooring, so I may be able to buy some more, even if the dye lot is different it will create that artistic look ???? If not, well, I'll cross that bridge when I come to it.
The raised area is just so uniform as if it's being pushed up by a layer of air or vapor as Carey says. It does not look as if a tree root has grown underground. It would have had to go under a big area of concrete outside the house and reach out to the middle of this floor without damaging any of the concrete outside nearer to the trees. That would be a real fluke.
I'll let you know what I find when we do take up some of the tile. Thanks again!
