The Texas Railroad Commission on Tuesday said it has posted information online about injection wells in the Azle area where a series of small earthquakes rocked residents last year.

Azle Mayor Alan Brundrett and other officials had complained that data such as injection volumes and pressures was updated only once a year and left them in the dark.

The Railroad Commission said staff seismologist Craig Pearson “is facilitating the data exchanges between operators and academic institutions interested in conducting the research required to ultimately determine the cause of recent seismic activity in Parker and Tarrant counties.”

The agency did not interpret the data, which was provided by five of the seven operators of injection wells in the area.

Officials in Arkansas, Ohio and Colorado have linked earthquakes with nearby wastewater injection wells, but Texas and Oklahoma regulators have not established such a link. Researchers at the University of Texas at Austin have also concluded that there were possible links between injection wells and seismic activity at Dallas/Fort Worth Airport and around Cleburne in 2009-2010.

The quakes are the subject of a public meeting scheduled at 7 p.m. Wednesday at Azle High School, 1200 Boyd Road. Scheduled speakers include Reno Mayor Lynda Stokes, state Rep. Phil King, R-Weatherford, and SMU geophysics professor Heather DeShon.

The forum is sponsored by KERA/90.1 FM and StateImpact Texas, a public radio collaborative.
