..........Sig, it all depends on what kind of floor it is. It might be concrete base with a sand and cement "screed" on top (about 2inches/50mm thick). Sometimes the screed lifts for various reasons - if so, you might get away with removing the damaged area and patching with new.
If the whole thickness of the floor has lifted - then it could be along the lines of what Cleversod talked about - or possibly clay "heave" where the clay has swollen with all this wet weather.
Whichever - you have to be there to tell :o)
Sorry I can't be more help.

As The Builder says, sometimes a bulge is due to the failure of the screed laid on top of the floor. My next door neighbour had a similar problem - she was convinced that the roots from a tree outside had come into her house and had caused the floor to rise up in places. When I lifted the carpet, I discovered that it was just that the screed had cracked and disintegrated in areas of heavy wear and tear.
If you lift your carpets, can you take a picture of the *naked* floor (put it on something like photobucket) and give us a link to it.
