Did anyone watch Sunday Program on sinkholes, I would not want to be living in Florida after watching this program. I am checking out my US insurance policy.

There was also mention of the concerns in the Northern suburbs of Perth, as the developments roll out, scientists are worried the ground on which they're built may buckle under the pressure. New suburbs are being developed on highly porous limestone, unfortunately it is this substance that is prone to collapsing without warning.
I can not recall how many years ago now, but someone in northern corridor of Perth woke up to find a sinkhole in their backyard. That's a real problem, try selling that sucker.
