U.S. earthquake increase – tied to disposal well boom
Yesterday, reported in USAToday, it was reported that the increase of earthquakes which seems to have accompanied the U.S. energy boom, have now been statistically tied into Fracking.

Temblors appear tied to wastewater from energy drilling that is injected deep underground, putting pressure on quake faults.
The recent study out provides the strongest link to date between wastewater wells and quakes.
Seismologists and geologists say U.S. earthquakes have become roughly five times more common in the past three years. They warn about inadequate monitoring of deep wastewater disposal wells that are setting off these small quakes nationwide.
There are more than 30,000 such deep disposal wells nationwide. They’re increasingly used as mile-deep dumping grounds for fluids left over from the more shallow hydraulic fracturing, or “fracking,” wells responsible for surging U.S. natural gas and shale-oil production.
