Oklahoma State Regulators Consider New Restrictions After Earthquake

Another earthquake shook Oklahoma Tuesday night, causing state regulators to consider new restrictions on some oil and gas activity in order to prevent more quakes caused by underground disposal of wastewater from production.

The 4.5 magnitude earthquake struck Pawnee, Oklahoma and was reported to have also been felt in parts of Kansas and Missouri. Tuesday’s earthquake comes just two months after the record-setting 5.8 magnitude earthquake that hit the state in the same area.

Scientists have linked the increase of earthquakes in Oklahoma to the underground disposal of waste water from oil and gas production. As a result, the corporation commission has already begun shutting down some disposal wells while ordering a decrease in the amount of wastewater disposed in other wells.
