Scientists offer possible explanation for how oil and gas activity may have triggered Dallas earthquakes

Post by Newsman »

In a long-awaited study, researchers have offered a possible explanation for how oil and gas activity may have triggered earthquakes in Dallas and Irving last year.

The disposal of wastewater from oil and gas production and hydraulic fracturing “plausibly” set off the tremors, which shook Dallas, Irving, Highland Park and other cities from April 2014 through January 2016, said Matthew Hornbach, the study’s lead author and professor of geophysics at Southern Methodist University.

While the quakes were too small to cause much damage to buildings, they spread alarm through a metro area unaccustomed to feeling the ground shift.

The quakes contributed to a tenfold increase in North Texas’ earthquake hazard level, prompted the Federal Emergency Management Agency to warn of stronger quakes that could cause billions of dollars of damage, and moved local emergency managers to begin preparing for worst-case scenarios.
