Oklahoma just magically happened to become an earthquake zone spontaneously. I know this because a government website told me so.
Read the article carefully. Its generally not the fracking that causes earthquakes...its (maybe) injection wells. And most injection wells in Oklahoma dispose of fluids from conventional wells.
Ergo, when the media scream ‘fracking causes earthquakes’, they are not being honest.
What (may) have happened is that an uptick in oil production in Oklahoma due to a period of high oil prices caused more injection well use. That’s what ‘magically’ made OK an earthquake zone - not fracking my hair’s on fire fracking.
Just like climate change data, the errors in logic occur because people tend to evaluate results through recorded history rather than the span of history which is eons. Reliably recorded history in the US generally is about 250 years. In the area of Oklahoma, more likely 150 years.
BTW I went to the University of Oklahoma in the 70's and we had our share of earthquakes then in Norman, way before fracking.
