Flushing the toilet shakes the house

This surrounds the toilet but I'm guessing its more than a toilet issue. Whenever you flush 1 of the 3 toilets in the house it sounds like there is a very big truck going by right outside and you can feel something in the house shaking / vibrating. None of the other toilets or water using devices causes a similar reaction.

Any ideas would be appreciated.

Thanks

The quickest and easiest thing you can try is to open the shutoff to the fill valve all the way.

the valve under the toilet that shuts off the water?

Yes, it's the first thing I check in your situation.
And the easiest.
Just do it.
