“Even small vibrations at ground level can be the sign of far more damaging impacts deep underground.”
"That has some very interesting and I think important consequences for how we understand the hazard posed by oilfield wastewater disposal."
New research has now linked distant earthquakes to fracking, providing evidence that much larger areas surrounding sites may be at risk from drilling operations than previously demonstrated.
The important insight of this study is sedimentary rock injection is not a safer alternative to basement injection.
“If an earthquake comes through here and destroys the buildings, we can rebuild. But if you pollute our water, we’re done."
Eaton says he hopes the research will result in better regulation and risk assessment processes.
Despite overwhelming scientific evidence that these dangerous wastewater-injection practices cause destructive quakes, the BLM failed to consider these effects in its evaluation of its latest lease auction in April 2016.
Oklahoma has become the world capital of earthquakes.
It cannot be ruled out that the Long Beach earthquake, which killed 115 people, was induced by oil drilling activities.
