An earthquake measuring 3.7 startled some East Texas Residents in Nacogdoches, Shelby and Panola counties around 10:15 a.m. Thursday.

According to the National Weather Service, the center of the earthquake was located about 2 miles west southwest of Timpson and was felt in the cities of Garrison and Nacogdoches.

According to Jason Hansford, senior meteorologist at the National Weather Center in Shreveport, the earthquake could have been caused by drilling for natural gas in the area.

“It could be fracking issues,” Hansford told KTRE in Lufkin. “It’s just a theory, but we don’t have any significant fault lines.”

No injuries or damage has been reported.
