Wastewater injection can make faults twice as likely to fail, quake study says

When earthquakes first jolted Dallas-Fort Worth residents in the fall of 2008, academic researchers knew little about the dense network of faults that run through our region. Now, two newly published studies offer the most complete picture yet of the fissures beneath North Texas and the thousands of small earthquakes they have hosted.  The new research also shows that wastewater injection from oil and gas operations makes faults much more likely to slip. When scientists modeled fault behavior before and after wastewater disposal, they found that disposal pressures could double the chance of earthquakes. The findings solidify the conclusion that North Texas quakes have been triggered by humans and not by Mother Nature.  Read more.....
