Dallas Morning News: Fracking-related activities have caused majority of recent Texas earthquakes
Science journalist Anna Kuchment with The Dallas Morning News covered the research of SMU seismologists on the historical record of North Texas earthquakes and their causes.
The SMU seismology team on May 18 published online new evidence of human involvement in earthquakes since the 1920s in the journal Seismological Research Letters. The study found that human-caused earthquakes have been present since at least 1925, and widespread throughout the state. While they are tied to oil and gas operations, the specific production techniques behind these quakes have differed over the decades, according to Cliff Frohlich, Heather DeShon, Brian Stump, Chris Hayward, Mathew J. Hornbach and Jacob I. Walter.
