The hole was filled with concrete, etc and sunk another 6 ft. I realize it was settling however, what's to stop it from sinking further?

Good reasoning; we've been wondering the same.
It's great to be eternally optimistic, but foolhardy not to do the research. There is a wealth of info on Florida sinkholes out there.
Also, which counties they are more prevalent and less prevalent......more severe, less severe; more prone to happen etc.

No one has control over Mother Nature's hurricanes, tornados, tsunamis, flooding, etc........but one does have a choice as to where to build or buy their retirement home.

The hurricanes and tornados do not particularly bother me as there will be some warning. Not so for these sinkholes or worse yet, a catastrophic ground collapse. We are definitely not naïve to think they will never occur again, repeatedly......especially with climate change and more frequent rains. Florida's climate has definitely changed, along with the rest of the U.S.

Very educational; keep scrolling downward.
