Two giant sinkholes sit between Wink and Kermit, Texas. New satellite images suggest the two existing holes are expanding, and new ones are forming as nearby subsidence occurs at an alarming rate. A new study by geophysicists at Southern Methodist University, Dallas, finds the massive sinkholes are unstable, with the ground around them subsiding, suggesting the holes could pose a bigger hazard sometime in the future. The two sinkholes — about a mile apart — appear to be expanding. Additionally, areas around the existing sinkholes are unstable, with large areas of subsidence detected via satellite radar remote sensing. That leaves the possibility that new sinkholes, or one giant sinkhole may form. This is similar to Arizona where giant cracks mysteriously appear deep in the ground. This area is heavily populated with oil and gas production equipment and installations, hazardous liquid pipelines, as well as two communities. The intrusion of freshwater to underground can dissolve the
