Have lived in Florida 30 years. Sinkholes seemed to occur largely around the areas where there were many lakes, ie, Central Florida. It has to do with the limestone aquafirs and the fact that our groundwater is just a few feet underground in most of Florida. So anywhere it is possible and I've heard of them in many parts of this state and now many other states where one would not suspect they would be. Just more, it seems in central Florida. When there is a lot of rain, it causes more to occur. They are random and unable to predict, although probably areas of possibility. Like earthquakes in California, you have to hope you can get good insurance, but I read that insurance is more restricted as more occur. Do your research and check your policy. Like any insurance, do that before you need it.
