From Newsweek:
An area of Texas could be set to receive more earthquakes as seismic activity moves along a newly activated fault zone.
Researchers from the University of Texas at Austin looked at seven years’ worth of earthquake data from the Midland Basin, a huge sedimentary basin in the Southwest, to reach these findings. The basin is a major oil field. Wastewater used for operations, which is injected into the surface, has resulted in multiple stresses along the fault lines.
