The Sierra Club filed a federal lawsuit today against three Oklahoma energy companies over earthquakes linked to oil and gas production.

The lawsuit, filed in the U.S. District Court for the Western District in Oklahoma City, accuses Chesapeake Energy, Devon Energy and New Dominion of operating wastewater injection wells that have contributed to a massive spike in earthquakes in Oklahoma and Kansas.

A 5.1-magnitude earthquake that struck  northwestern Oklahoma over the weekend was widely felt in Kansas City and as far south as Dallas and could be one of the largest ever recorded in Oklahoma.

The U.S. Geological Survey says Saturday’s late-morning temblor is likely the state's largest since 2011, when a 5.6-magnitude temblor injured two people and damaged homes near the town of Prague.

Steve Foster, the emergency manager for Woods County, says no injuries or major damage were reported from the intense Saturday quake or its aftershocks.

Oil and gas companies want to comply with regulators’ requests to shut down disposal wells if it blunts the boom of earthquakes, but they want the state to clarify the process used to dispute such requests, The Journal Record’s Sarah Terry-Cobo reports.

Scores of worried residents sounded off to state lawmakers at a pair of public meetings on Thursday and Friday about Oklahoma’s earthquake boom. Republicans and Democrats each held their own earthquake hearings. Both were rowdy.

People spoke out about home damage, insurance problems and potential injuries. They also chastised state officials for failing to rein in oil and gas activities linked to the shaking. At the Edmond meeting organized by Republican Representative Lewis Moore, people interrupted and yelled.
