Reporting Subsidence Incidents

Various types of subterranean events can cause holes, depressions or subsidence of the land surface that may mimic sinkhole activity. These include subsurface expansive clay or organic layers which compress as water is removed, collapsed or broken sewer and drain pipes or broken septic tanks, improperly compacted soil after excavation work, and even buried trash, logs and other debris. If a hole or depression is not verified by a licensed professional geologist to be a true sinkhole, and the cause of subsidence is not known, it is called a subsidence incident.

You may use the short form below to initiate a subsidence incident report, after which you will be contacted by a Florida Geological Survey geologist.
