Sinkhole Research

Sinkholes are a geological hazard that place people’s property and even lives at risk. Vulnerability of an area to sinkhole formation is dependent upon both natural (geologic, hydrologic and meteorologic) and human (water pumping, terraforming, ground loading) factors. As Florida’s population continues to surge, the potential for encountering a sinkhole hazard in areas with the favorable geology increases.

The Florida Geological Survey (FGS) was contracted, back in 2013, by the Florida Division of Emergency Management (FDEM) to produce a map depicting the state’s favorability to sinkhole formation based on natural dynamics in Florida’s geology.  The map was requested in the aftermath of a mass sinkhole event triggered by record rainfall from Tropical Storm Debby in June of 2012. Prior to Tropical Storm Debby’s record rainfall, the state had been experiencing a multiyear drought leading to reduced groundwater levels within the Floridan aquifer system. The three-year project began with a pilot study in three northern Florida counties where various modeling and statistical methods could be tested prior to initiating a statewide approach. The study’s aim was to update the non-scientifically derived sinkhole maps that were utilized by the State’s emergency managers. Click here to download a pdf copy of the report deliverable.
