About this layer
Florida sits on limestone that slowly dissolves, which is why sinkholes are a real concern for homeowners there. This layer maps 4,457 subsidence incident reports from the Florida Geological Survey. Most reports are unverified, meaning someone reported ground settling or a depression that was never confirmed as a sinkhole; about 100 are confirmed sinkholes.
That context matters, so read the map as a record of reports, not a risk rating. It is useful for curious residents, buyers researching an area and students learning about karst geology. Clusters in west-central Florida stand out. Pair it with Cave Entrances and Drinking Water and Springs to explore other features of karst country.
