What is the sinkhole risk factor associated with my area?
Unfortunately there is no ready reference on sinkhole prediction or risk assessment. The insurance companies have tried developing some sort of risk prediction methodology, but since the underground cavities are largely undetectable without expensive ground-penetrating radar surveys, resistivity tests, or test drilling, no real progress towards this goal has been made. About the most we can presently do is construct regional maps such as our, Sinkhole, Development and Distribution in Florida Map, showing zones of sinkhole occurrences based on the local geology and historical sinkhole activity.
