Short summary
Sinkhole activity in west-central Florida is a major hazard for people and property. In this work, we use radar interferometry acquired over a selected region in Hernando County in west-central Florida to observe small localized deformation possibly caused by sinkhole activity. Results reveal several areas of localized subsidence at rates ranging from −3.7 to −4.9 mm/yr.
