| description | <p>Sinkhole activity in west-central Florida is a major
hazard for people and property. Increasing frequency of sinkhole collapse is
often related to an accelerated use of groundwater and land resources. 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. The data used for the
study consist of acquisitions from one TerraSAR-X frame covering a time span
of approximately 1.7 years with spatial resolution of 0.25 by 0.60 m. We
applied the Persistent Scatterer Interferometry (PSI) technique using the
Stanford Method for Persistent Scatterers (StaMPS). Results reveal several
areas of localized subsidence at rates ranging from <span class="inline-formula">−3.7</span> to <span class="inline-formula">−4.9</span> mm yr<span class="inline-formula"><sup>−1</sup></span>.
Ground truthing and background verification of the subsiding locations
confirmed the relationship of the subsidence with sinkhole presence.</p> |
