Why Are There So Many Sinkholes in Florida? - The Atlantic:
"Reports of sinkholes show up in Florida newspapers so often, they deserve their own section.
But Kromhout says, despite popular perception, that there does not seem to be an increase in sinkholes across the state. 
“I am doubtful that sinkholes are occurring any more frequently than any other time with Florida’s recent geologic past,” says Kromhout.
(Then again, Kromhout says he isn't aware of any studies that have assessed sinkhole frequency over time.)"
