Azle Earthquakes Likely Caused by Oil and Gas Operations, Study Says
April 22, 2015

Oil and gas operations are the most likely cause of dozens of earthquakes that began rattling the North Texas towns of Azle and Reno in November 2013, a group of scientists has concluded.
The study, led by researchers at SMU and published Tuesday in the journal Nature Communications, presents some of the most conclusive evidence yet that humans are shifting faults below Dallas-Fort Worth that have not budged in hundreds of millions of years.
Cliff Frohlich, associate director of the University of Texas Institute for Geophysics, contributed to the research.
