House shaking?

There's a few possibilities I can think of, it may not be the case, or it could be a combination of them.

1) Houses expand and contract with heat, both outside from the weather + inside because of the heating/cooling systems in place.

I've heard of instances of houses in cold climates totally collapsing after they've been left with the heating off while the owners were away for an extended period because of this.

I've also heard of people having the plasterwork blowing & cracking from drying out too much after they've been running the central heating too high.

2) It could be subsidence, where the foundations screw-up because of problems with the ground it's built on, combined with the weight of the building on top of it... or other foundation issues.

3) It could be an issue with the joists in the framing of the house, for instance if it's an old house built before it was considered necessary to use joist hangers.

They've also been known to go wrong if the house has had plumbing or electrical work done retrofitting pipes or wires through it, and the person fitting them took a chunk out of the joist incorrectly.

Or they can just rot through if there's moisture getting in somewhere when there shouldn't be.

Maybe you are on a slab that has cracked and is now broken. Part of the house is settling/moving at a different rate causing fractures. 

A large, low flying aircraft can do this. Was the military doing a rare bombing run practice in your area? {As an Air Force veteran I kid you not. I also now live near a major airport so my house shakes, rattles, and sinks (thus creating a ceiling crack) once in a long while - especially in the past, before the new airplanes came along.}

sounds like a minor earthquake. check local news

If your area was not hit with an earthquake, then the house is settling and possibly moving off its foundation. The house should be checked to see if the ground is sinking or is moving and causing the house to move with it. Might even be on a sink hole who knows at this point.

If the house is on a concrete slab, then the slab should be checked for cracks as well.

Where are you? If that's not from an earthquake, you've got a big problem. Are you near fracking fields?
