Study: Injection wells can induce earthquakes miles away from the well

This article discusses a study that shows that fracking injection wells can induce earthquakes miles away from the well. Study finds injecting fluid into sedimentary rock can produce bigger, more distant earthquakes than injecting into the underlying basement rock. A study of earthquakes induced by injecting fluids deep underground has revealed surprising patterns, suggesting that current recommendations for hydraulic fracturing, wastewater disposal, and geothermal wells may need to be revised.
