Lump Deveoping in Middle of Kitchen Floor

We have noticed a raised lump in the middle of our kitchen floor. It a gradual hill type. It's approximately 3 inches high.

There is a basement underneath the about 1/3 of the kitchen. Where the lump is in the kitchen is right about the end of the basement underneath it. The rest of the kitchen sits on concrete slab with ground underneath it.

What do I do? I am concerned about ripping up the tile floor underneath it but I don't feel like I have any other option.

How worried should I be? What could have possibly caused it? What can I do about it?

We think it may have started after Hurricane Sandy last year. We live in NE PA.

Take a walk around the outside of your home and look for cracking or an uneven roof line. A 3" lump is major and means something is moving up or something else is moving down.

An easy way to gain knowledge is to request an estimate for repair. A pro knows how things were put together and has a good chance of spotting what has moved. Plus, you get a price to compare to your possible DIY. Once you have 2 or 3 estimates you will have a much better idea as to what you are facing.

The house is very old. Initial paperwork when we bought said 1910 or so. According to the realtor that's the age they put when they don't know but it's old. The house was likely built up at least 3 times. Just prior to our purchase about 2 years ago, the kitchen was drastically remodeled. According to our neighbor, this included removing an island that was in the middle of the kitchen(possibly near the lump) and new tile floor.

I agree with Bud, that the exterior walls of the house are settling and there is a beam directly under this remodel that is NOT sinking. Simplistic diagnosis, but may be right.
