Weekend Dallas Earthquakes Occur in Fracking Hot Spot
A series of small earthquakes in the Dallas region over the weekend are reviving discussion of the link between quakes and the oil and gas industry practice of hydraulic fracturing, or “fracking.”
Fracking is the practice of pumping hydraulic fracturing fluid into wells to break up and extract oil shale and natural gas deposits. Just how fracking is linked to earthquakes is a hot topic around the country, Texas especially.
StateImpact Texas writes that it’s not the actual act of fracking itself that leads to earthquakes, but rather the disposal of the fracking fluid remaining after the process, which is usually shot into disposal wells deep underground.
A study from the National Research Council (NRC) “indicates that long-term disposal wells can be linked to increased seismic activity.”
