Determination of Sinkhole Activity in Granular Sediments in West-Central Florida



A new method is presented for determining the presence of “sinkhole activity” using the current (2017) Florida statute. The new method uses a modified raveling index (modified with normalized N-values) for verification of “sinkhole activity” together with consideration of other non-sinkhole causes of building distress. In addition, the problems associated with detecting cover collapse and cover subsidence sinkholes are also considered. Difficulties in applying the Florida statute are also discussed, and recommendations for improvement of the statute are provided.
