READ MORE: AllGov - News - Arkansas Suspends Drilling of Injection Wells after Earthquake Swarm: "After months of earthquakes, including the largest felt in 35 years, the state of Arkansas has ordered a temporary moratorium on the drilling of new injection wells related to natural gas-related drilling, which some locals believe are causing the seismic activity. More than 700 small earthquakes have been recorded in north-central Arkansas in the last six months.
Although the earthquake swarm might be a natural occurrence, it is also possible that it has been a consequence of the natural gas drilling technique known as “hydraulic fracturing” or “fracking.” The process entails injecting millions of gallons of chemicals, sand or fluids into a well to crack open the rocks and allow easier access to the natural gas. The problem in Arkansas appears to be related not to the drilling itself, but to the disposal of wastewater from the drilling by forcing it back into the earth into injection wells."
