Fracking Increases Oklahoma Earthquakes

5.0 02 Oklahomans are accustomed to scorching heat, driving thunderstorms and deadly tornadoes. But not earthquakes—until recently, the state never had more than 11 earthquakes a year that measured 2.0 or greater on the Richter scale. In 2013 there were 291. More than 250 earthquakes of at least that magnitude have struck in February 2014 alone. -It’s incredibly unusual ,” […]

Tremors from fracking

5.0 01 Prague, Okla Tremors from fracking: Scientists have linked Oklahoma’s largest earthquake—a 5.6 magnitude quake near the town of Prague, in 2011—to hydraulic fracturing, supporting claims that the process increases seismic activity. Fracking, as it is known, injects water and chemicals into petroleum deposits in order to extract trapped gas. This week, researchers at the University of Oklahoma, Columbia […]

Fracking’s seismic impact

Fracking

5.0 01 Geologists are warning that fracking may be leading to an increase in seismic activity. A recent advisory from the U.S. Geological Survey warns that activities related to hydraulic fracturing—or fracking, extracting oil and natural gas from subterranean rock formations—has likely contributed to the recent spike in earthquakes in Oklahoma, and experts warn that the chances for a major […]
