AZLE -- The Tarrant County community of Azle was rattled by a 2.7-magnitude earthquake Tuesday morning.

It was the first earthquake in December after 19 earthquakes were recorded in the area in November.

Tuesday's quake was intially recorded with a magnitude of 3.4 but was downgraded to a 2.7 within the hour.

The tremor was felt at 9:44 a.m. with the epicenter was two miles north of Azle and 11 miles west-northwest of Saginaw next to Eagle Mountain Lake according to the U.S. Geological Survey.

Azle mayor Alan Brundrett expressed concern about the cause of the quakes last month. A University of Texas earthquake researcher told News 8 waste water injection wells from fracking may have led to the tremors.

Chad Lorance of the Tarrant Regional Water District told News 8 dams in the area are inspected daily and there are sensors in the dams that would alert them to any shift. A previously-scheduled annual crest survey of the dams will be conducted next week to look for changes from surveys in the past.

The Tarrant Regional Water District spokesman also told the Fort Worth Star-Telegram his department would contact the Texas Railroad Commission, which oversees oil and gas production in the state, in order to 'stay up to date on any oilfield-related activity.'
