Earthquakes

Earthquakes are increasingly being linked to drilling activities, whether it is for gas or oil, or for the disposal of waste materials.

- 1725 - [April 15, 2015] - The Wall Street Journal, Miguel Bustillo and Dan Molinski - "New Studies Link Earthquakes With Oil, Gas Drilling"
"New scientific findings released Tuesday linked earthquakes to the practice of injecting wastewater from oil and gas operations deep underground, adding to a growing consensus among researchers that energy development is probably causing seismic activity in Oklahoma, Texas and other parts of the U.S."
- 1726 - [April 21, 2015] - Los Angeles Daily News - Earthquakes, Alicia Chang, The Associated Press - "Oil, gas drilling triggers earthquakes in over a dozen areas in the US"
"More than a dozen areas in the United States have been shaken in recent years by small earthquakes triggered by oil and gas drilling, a government report released Thursday found.
The man-made quakes jolted once stable regions in eight states, including parts of Alabama, Arkansas, Colorado, Kansas, New Mexico, Ohio, Oklahoma and Texas, according to researchers at the U.S. Geological Survey.
Experts said the spike in seismic activity is mainly caused by the oil and gas industry injecting wastewater deep underground, which can activate dormant faults. A few instances stem from hydraulic fracturing, in which large volumes of water, sand and chemicals are pumped into rock formations to free oil or gas."

"Yet another study has found a link between hydraulic fracturing and earthquakes. This one examined 77 minor quakes near the Ohio-Pennsylvania border. "
- 1728 - [January 7, 2015] - Pittsburgh Post-Gazette, Don Hopey / Pittsburgh Post-Gazette - "Study: Fracking caused earthquakes in existing faults in Ohio"
"A scientific study has linked hydraulic fracturing to 77 minor earthquakes last March around Poland, Ohio, just across the Pennsylvania-Ohio line.
The sequence of seismic events, including a rare “felt” quake of a magnitude 3.0 on the Richter scale, was caused by active “fracking” on two nearby Hilcorp Energy Co. well pads, according to the research published online today in the Bulletin of the Seismological Society of America."
- 1729 - [January 5, 2015] - The Daily Campus, Jamie Buchsbaum - "'Did you feel that?' SMU seismology team reveals North Texas earthquake findings"
"Since 2008, more than 120 earthquakes have been reported in North Texas. Prior to 2008, an earthquake hadn’t been felt in the area since 1950, according to SMU seismologists.
An SMU-led seismology team consisting of two associate professors of geophysics, Matthew Hornbach and Heather DeShon, revealed their findings from the Azle-Reno region of Texas in a brief press conference-style lecture Tuesday afternoon. The lecture was held in Heroy Hall for around 25 attendees."
- 1746 - [April 2015] - abc NEWS, Seth Borenstein AP Science Writer - "Study Links Swarm of Quakes in Texas to Natural Gas Drilling"
" With real-time monitors, scientists have linked a swarm of small earthquakes west of Fort Worth, Texas, to nearby natural gas wells and wastewater injection.
In 84 days from November 2013 to January 2014, the area around Azle, Texas, shook with 27 magnitude 2 or greater earthquakes, while scientists at Southern Methodist University and the U.S. Geological Survey monitored the shaking. It's an area that had no recorded quakes for 150 years on faults that "have been inactive for hundreds of millions of years," said SMU geophysicist Matthew Hornbach.
When the volume of injections decreased significantly, so did the shaking."
- 1747 - [April 21, 2015] - abc NEWS, TIM TALLEY Associated Press - "Oklahoma Geology Group Links Earthquakes to Oil Waste Wells"
" 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.
A statement released by state geologist Richard D. Andrews and Dr. Austen Holland, state seismologist, said the rate of earthquakes and geographical trends around major oil and gas drilling operations that produce large amounts of wastewater indicate the earthquakes "are very unlikely to represent a naturally occurring process.""
- 1748 - [April 21, 2015] - abc NEWS, Evan Simon - "Oklahoma Admits Oil and Gas Industry Responsible for Dramatic Rise in Earthquakes"
" For the first time in the state's history, Oklahoma’s state government officially recognized the long held scientific consensus linking the disposal of oil and gas wastewater with the record number of earthquakes plaguing it in recent years.
On Tuesday, the Oklahoma Geological Survey released a statement declaring it was “very likely that the majority of recent earthquakes, particularly those in central and north-central Oklahoma, are triggered by the injection of produced water in disposal wells.” "
