Central Florida faces unique challenges, like Pinellas County. It has porous limestone bedrock, which is key to karst terrain. Groundwater dissolves this rock, making underground cavities that can collapse suddenly. The Florida Department of Environmental Protection says this process causes 63% of subsidence events.

Between 2003 and 2023, 127 sinkholes were confirmed in cities like Clearwater and St. Petersburg. A 2016 incident near Largo damaged three homes. In 2020, a sinkhole in Seminole disrupted water services for weeks. Human actions, like old septic systems and over-pumping aquifers, cause 37% of sinkholes, state records show.

People can check their risk with county resources. These tools show where sinkholes might happen. It’s important to watch for signs of instability, as weather changes can speed up erosion.

It’s key to know the difference between natural sinkholes and those caused by human actions. While nature plays a big role, human mistakes like water main breaks and bad drainage also cause problems. This helps in planning for emergencies and the future use of land.
