The latest news from around North Texas.
The fifth 2.5 magnitude quake was reported at 2:50 p.m. Tuesday in the 10400 block of Wildwood Drive north of where State highway 114 and Loop 12 and the old Texas Stadium site.
Three dozen earthquakes have been recorded around that same area since October; no injuries or significant damage have been reported in any of the earthquakes.
At a public town hall meeting Tuesday evening at the Irving Arts Center to hear residents' concerns about the earthquakes, Irving city leaders announced they would withhold judgment or comment on a cause until more information is available.
"This is a Texas issue. And I know that all of us want to get down and find out what is causing this activity and what we can do to stop it, if anything," said Irving Mayor Beth Van Duyne.
The meeting had an overflow crowd in the 250-person capacity theater.
Several city residents spoke about their concerns, most notably the fear that the many processes involved in natural gas drilling have contributed the the earthquake swarm.
A handout provided by the City of Irving highlighted several rebuttals to those concerns, including a statement that there has been no fracking in the city since 2010, that there has never been any waste water injection done within the city limits and that, by city ordinance, any waste water produced from drilling in Irving was trucked out of the city.
That information did not satisfy many of the residents who spoke, with some suggesting that natural gas production on the nearby grounds of Dallas-Fort Worth International Airport could play a role, and that the earthquakes do not respect municipal boundaries.
