Earthquakes have not been tied to fracking. They have however, been tied to wastewater injection wells used by the oil and gas industry and many other industries. Wastewater injection wells are used to dispose of toxic water and other substances deep below the surface of the Earth between 10,000 and 12,000 feet—about twice the depth of fracking. When pumped too fast, water at this depth can lubricate basement faults and cause minor seismic tremors. Under Colorado’s stringent regulations, companies must conduct the proper geologic surveying to locate basement faults, then regulate their rate of injection. When the oil and gas industry—or any other industry—adheres to these regulations, the risk of earthquakes should be eliminated. This article
contrasts how Kansas and Oklahoma have handled earthquake issues, and fortunately for Coloradans, our state has tackled the issue in a similar manner as Kansas.
