The city of Irving, Texas has experienced five earthquakes in four days, leading some critics to blame increased seismic activity on nearby fracking operations.
The first earthquake, Saturday night, was a magnitude 3.3 quake that was felt by hundreds of North Texans. A 2.5-magnitude quake hit on Sunday, followed by two more on Monday, magnitudes 2.2 and 2.3. And a fifth 2.7-magnitude earthquake was reported Tuesday evening just east of the University of Dallas campus.
Residents and city leaders point to area oil and gas disposal wells, where fracking wastewater is injected deep underground, as likely culprits. There is a wastewater disposal well near the epicenter of Saturday’s quake.
“We are guinea pigs in the middle of this fracking experiment. Texas homes are built to withstand wind, not earthquakes,” Sharon Wilson, an organizer for the advocacy group Earthworks, told Reuters. “Who will pay for the damage to private property?”
