A jump in the number of earthquakes in Oklahoma, and across the north central U.S. from Colorado to Ohio. Is it just a coincidence the increase in seismic activity if happening along with oil activity?
That’s what scientists and regulators are trying to determine. Some seismologists believe waste water injected back into the ground is triggering earthquakes. The deputy chief of the US Geological Survey says “there’s a couple of good examples where I think it’s pretty clear that if you turn off the well the earthquakes stop. It’s a pretty strong correlation.”
Oil companies don’t buy it. The president of the Mid-Continent Oil and Gas Association of Oklahoma Chad Warmington, says, “we’ve been doing injection in the state for a long time. It deserves a lot more investigation before making a determination.”
