Fracking has been connected to increase earthquakes in nearby areas. Steve Rushton explains that “In the area between Alabama, Colorado and Ohio, where fracking is most prolific, insurers note how forty years ago the area averaged 21 earthquakes per year. It rose for the decade before 2011 to 134, that year” (Rushton, 2014). The increase of fracking caused earthquakes has raised national concern, typically these earthquakes are too small to cause damage. The earthquakes have been made worse by the water remaining underground left over from fracking (Lieberman, 2016). This is a long term impact of fracking that can continue to damage the environment over time.
