3.5 intensity earthquake rattles North Texas; no damage reported

An earthquake measured at 3.5 magnitude caused a stir in North Texas, but no damage was reported.

The U.S. Geological Service plotted the epicenter of the 3:10 p.m. Tuesday temblor as Texas 183 about 100 yards southeast of Spur 482 in eastern Irving. The quake occurred within an area near the Elm Fork of the Trinity River that has seen a swarm of mild temblor in recent months.

The earthquake was felt throughout the Dallas-Fort Worth area.

The swarm has prompted Southern Methodist University seismologists to plan the installation of more measuring equipment in the area.

Small earthquakes have become more common in Texas and Oklahoma. In October, Texas officials amended rules for disposal well operators amid concerns that high-pressure injections related to hydraulic fracturing, or fracking, can trigger earthquakes.
