The objective of this study is to measure land-surface subsidence in southwest Utah using Interferometric Synthetic Aperture Radar (InSAR). During the winter of 2004/2005 the Utah Geological Survey documented earth fissures near Beryl Junction in Iron County, Utah. The UGS concluded that these fissures formed due to groundwater withdrawal in the area, which has caused compaction in the Escalante Valley aquifer and ground subsidence near Beryl Junction. This study uses InSAR to measure potential surface displacement in the Escalante Valley and investigate other locations of potential subsidence, specifically in the Parowan and Milford areas.
