In the first part of my series on earthquakes and fracking in Oklahoma, I wrote about the correlation between hydraulic fracturing activity in the state and the increased frequency of earthquakes. As more injection wells came online in the state to dispose of the produced fluid from fracking operations, the state saw a vast increase in the number of earthquakes, primarily centered around north-central Oklahoma. While scientists are still determining why the earthquake activity is centered in certain parts of the state, they are almost certain that there is at least some correlation between injection well operations and increased seismic activity. But what can Oklahoma do to slow or stop the frequency of these earthquakes? I will address the issue in this post. Continue reading →
