Earthquakes have been increasing in Oklahoma and other states throughout the mid-continent, and many seismologists think this increased seismicity is linked to disposal wells used by the oil and gas industry.
The connection has caused oil and gas regulators in some states to re-evaluate how they issue permits for drilling. No such changes will be considered in Oklahoma until the state Geological Survey is more convinced of the link. The organization’s principal seismologist, Austin Holland, is a skeptic.
