Oklahomans Feel Way More Earthquakes Than Californians; Now They Know Why

Austin Holland, research seismologist at the Oklahoma Geological Survey, gestures to a chart of Oklahoma earthquakes in June 2014 as he talks about recent earthquake activity at his offices at the University of Oklahoma in Norman, Okla. The state had three times as many earthquakes as California last year.

A magnitude-3.0 earthquake is small, but most people can feel it. Historically, Oklahoma got less than two of those a year, but in 2013 it became two a week.

It's only gotten more active since then — last year, the state had three times as many earthquakes as in the entire seismically active state of California.

Geologists Link Oklahoma Earthquakes To Fracking Waste Disposal

Originally published on Thu April 23, 2015 2:24 pm

The Oklahoma Geological Survey said Tuesday it is “very likely” that most of the state’s recent earthquakes were triggered by the subsurface injection of wastewater from oil and natural gas drilling operations.

Geologists have been studying the cause of hundreds of earthquakes that have shaken the homes and the nerves of residents in central and north-central Oklahoma, where the pace of oil and gas drilling has accelerated in recent years.

As earthquakes continue to surge in Oklahoma and seismologists warn of more frequent and more damaging shaking, the state’s oil and gas regulator is issuing new orders to companies operating wells in seismically active regions of the state.

The Oklahoma Corporation Commission’s new requirements, known as directives, were mailed March 18 to 92 people or companies operating 347 Arbuckle formation disposal wells in quake-prone regions of the state.

As Authorities Use Permit Process to Scrutinize Wells, Oil Industry Remains Silent

As earthquakes continue to rattle Oklahoma and scientists study links to oil and gas production, many Oklahomans want to know what, if anything, is being done to address the shaking.

An investigation by StateImpact shows that while authorities are quietly scrutinizing wells in quake-prone parts of the state, most of the companies that operate the wells are staying silent.

Hearing on Disposal Well Rules Exposes Gaps in State’s Earthquake Response

Rep. Cory Williams, D-Stillwater, questions Secretary of Energy and Environment Michael Teague at an interim study and hearing about earthquakes and disposal well oversight held in October 2014.

Oklahoma’s earthquake surge is unrelenting. The shaking is rattling residents and cracking the foundations of homes.

The quakes have also strained state agencies, which are struggling to keep up with the ongoing swarm while simultaneously developing a longer-term plan to analyze and address factors that might be triggering the earthquakes.

High-Rate Disposal Wells Could Have Triggered Oklahoma Earthquakes, New Study Suggests

Joe Wertz / State Impact Oklahoma

This year, Oklahoma has had more earthquakes than California. There is a growing body of scientific research that suggests oil and gas production is fueling this increase in seismic activity.

new paper published today in the journal Science, suggests a small number of wastewater wells used in drilling operations could be responsible for many of the quakes.
