Should People Be Worried About Earthquakes From Fracking? Science Says No, Activists Say Yes

From The Daily Caller:
Monday’s earthquake came from the northern edge of the Santa Monica Mountains, an area that doesn’t see much seismic activity, lending fuel to the flames for environmentalists who argue fracking will cause more earthquakes.
But the evidence shows that fracking has little to no influence on seismic activity in California. Fracking involves injecting sand, water and chemicals into underground shale formations to extract oil and gas. Fracking operations generally pressurize a small amount of rock for about two hours which causes extremely small microseismic events, but nothing close to earthquakes.
“The energy released by one of these tiny microseismic events is equivalent to the energy of a gallon of milk hitting the floor after falling off a kitchen counter,” said Stanford university Geophysicist Mark Zoback, who was an Obama administration Energy Department advisor.
“Needless to say, these events pose no danger to the public,” Zoback added.
