Al Jazeera: Fracking-triggered earthquakes could become stronger over time as more wastewater is injected deep underground, new research suggests. It follows the release of several studies linking hydraulic fracturing directly to increased seismic activity.
Scientists attending the Seismological Society of America (SSA) annual meeting Thursday said that underground disposal of wastewater and fracking likely induce earthquakes by changing the state of stress on existing faults to the point of failure. Most...
