ALVARADO (CBSDFW.COM/AP) – Texas has had another minor earthquake.

The U.S. Geological Survey says a 2.6 magnitude quake happened around 4:00 a.m. Tuesday in North Texas.

Experts say the quake was centered about 1 mile south of Alvarado. The area is about 10 miles east-north of Cleburne and 25 miles south of Fort Worth.

No damage or injuries were immediately reported.

Minor earthquakes were recorded Saturday and Sunday in the same general area of North Texas, bringing the count to five quakes in three days.

Communities and neighborhoods in Johnson County seem to be feeling them the most. There have been few reports of damage, but area residents say their anxiety is rising along with the magnitude of the quakes.

“I wish they’d give us an answer, because they keep getting worse,” said Barbara Porter, a Burleson resident.

USGS says another quake happened early Sunday in South Texas near Tilden, about 100 miles northwest of Corpus Christi.

Experts say a 2.2 magnitude earthquake occurred Monday morning in Central Texas, about 13 miles southwest of Corsicana.

University of Texas at Arlington Science Dean Pamela Jansma says experts are researching area natural gas drilling, including the process of hydraulic fracturing, or fracking, as a reason for the earthquakes. Waste water reinjection could also be a reason –– but as of this moment, there’s no definitive connection.

“Whether or not anything happening now is associated with water injection, we just have no idea,” Jansma said.
