SqueeSAR™ is used to identify and monitor ground subsidence associated with sinkholes. 

Surface deformation maps can identify subsidence related to sinkholes, both prior to and following their collapse. As SqueeSAR™ is a remote sensing technique capable of identifying a high density of ground measurement points, many of the challenges in identifying and monitoring sinkholes using traditional ground based techniques can be circumvented.

Precursory Movement
SqueeSAR™ can detect surface displacements to millimeter accuracy occurring prior to sudden or rapid sinkhole collapse, otherwise challenging to detect using traditional techniques. Urban and rural areas can be monitored to detect small movements and identify areas at risk of developing sinkholes.

Ground deformation data can be used to identify hazards that could potentially threaten lives and damage infrastructure.

Sinkhole Characterization
Given the high density of ground measurement points detected using SqueeSAR™, sinkhole shape, extent and subsidence rate can be accurately determined. Post-collapse displacements on the ground surrounding a sinkhole can also be monitored to assess the potential of continued deformation along sinkhole borders.
