A 2.7-magnitude earthquake shook Irving at about 6 a.m. this morning. These minor events, none of which have caused significant damage or injuries, have been so common in the area (it’s the 12th since the beginning of October) that I’ve begun to feel downright Californian in my lack of excitement in hearing news of another.
The Morning News has a map showing the close proximity of the epicenters of each of these quakes to a natural gas well. Fracking, and more specifically the injection of wastewater from fracking being injected into the ground, has been found in some studies to be correlated with greater seismic activity.
A FrontBurnervian in the oil and gas business sent me a note with a map from a drilling industry information site showing the horizontal track of the well’s drilling bores was in the opposite direction from where the quakes are clustered. He argued that because of this, and because the well hasn’t been active since 2012, it’s likely not responsible for the tremors.
I ran this claim by Brian Stump, a seismologist at SMU.Full Story
