I guess to be somewhat safe, just avoid the area from The Villages to Crystal River down to Tampa/St. Pete if you want to increase your odds. However, nowhere in Florida is completely safe where there is limestone and sand base that is effected by water movement. The panhandle which has more of a clay base would be the safest area. When I lived in Pensacola we were over 100' above sea level and were less than a mile from Pensacola Bay. They have shorelines that are like California with steep cliffs.
