4.1 Earthquake Hits East Texas, Reports of Minor Damage

Update, Jan. 29: On January 29, very early in the morning, another quake struck Timpson, measuring 2.8, according to the USGS.

Original story, Jan. 25: A magnitude 4.1 earthquake struck about two miles Northwest of Timpson,Texas at around 1:00 AM this morning, shaking doors open, knocking pictures off walls, and causing at least one chimney to reportedly collapse in the small East Texas community. You can see where the quake struck in the interactive map above. It occurred three miles below the surface.

“It was like a rumbling, shaking, knocking-you-out-of-the-bed type feeling. It was very, very intense,” Timpson Municipal Court Clerk Paula Mullins told StateImpact Texas by phone. Mullins said she had heard of a neighbor’s chimney falling over, but no reports of injuries.

Quakes have become a semi-regular feature of life in the area lately. The strongest recent quake registered a 4.8 in May.

Researchers say previous quakes in the area have been caused by the use of disposal wells to store waste form oil and gas drilling. Timpson sits in the drilling area of the Haynesville Shale, one of several areas in Texas experiencing a drilling boom.

“At the moment, we are actually linking them [earthquakes] to injection wells that are located close to where the earthquakes are in the Timpson area,” Dr. Wesley Brown, an Associate Professor in the Department of Geology at Stephen F. Austin University told the regional newspaper Light and Champion in December. “We have one a little bit to the north, and [the wells] are north and south of each other,” said Dr. Brown. “The volume, especially for the one in the south, is up over 200,000 barrels of water per month.”

While researchers have known for decades that disposal wells can cause quakes, state regulators say they are waiting for more proof. The Texas Railroad Commission, the agency that regulates oil and gas drilling in Texas, is currently considering updated rules for disposal wells in the state, but it says it has no plans to include consideration of man-made earthquakes in that rule making.

A search on the Texas Railroad Commission’s online database of oil and gas wells shows ten active disposal wells in Shelby County, where the quake took place.

In a presentation to the American Geophysical Union in December, Brown presented a paper (along with Cliff Frohlich of the University of Texas at Austin and Michael Brunt of Eagle Pass Independent School District) on an earlier quake near Timpson. That paper found that the May 17, 2012 Timpson quake and another near San Antonio “are larger than any previous historically reported earthquakes in central and east Texas.”

“Numerous residents of Nacogdoches were awakened by the quake” in Timpson, the report says. “The highest intensities … occurred south of Timpson … where chimneys, fireplaces, and brick veneer siding suffered significant damage.”

And the October 2011 quake near San Antonio? Some people felt serious intensity, with “the shaking displaced and broke numerous small objects and masonry cracked.”

In Timpson, Court Clerk Mullins says she doesn’t remember many quakes in the area until around a year ago, but some quakes were reported there in the 1950s.

“I don’t know if it’s the oil wells or if it’s just the good Lord telling us to get ready,” Mullins said.

The magnitude of 4.0 is generally the point at which earthquakes begin causing light damage. A Level V, or 5.0 magnitude or higher, can damage poorly-constructed buildings. As the US Geological Survey notes, the impacts largely depend on where the earthquake occurs. “An earthquake in a densely populated area which results in many deaths and considerable damage may have the same magnitude as a shock in a remote area that does nothing more than frighten the wildlife,” they write on their webpage.

Another quake shook Irving, Texas in the Dallas-Fort Worth area earlier this week. Quakes have been on the uptick there since the oil and gas boom in Texas began several years ago. Some areas, like Dallas-Fort Worth, had previously had no earthquakes.

    Barry Smitherman is an angel. He swears ““We make decisions based upon the facts and the law,” said Smitherman, who said he is “unaffected by campaign contributions.” http://stateimpact.npr.org/texas/2013/01/25/big-changes-ahead-for-the-railroad-commission/

      Barry Smitherman is a liar! Everything RCT does is on behalf of the oil and gas industry. If RCT needs to know the facts it can always get them directly from the industry it regulates.

    “… State regulators say they are waiting for more proof.” More proof?! Maybe when Timpson,Texas, becomes oceanfront property, perhaps? Morons.

    “I don’t know if it’s the oil wells or if it’s just the good Lord telling us to get ready,” Mullins said.

    Now, THIS is the kind of logic that rational people need to lean on for assurances that the oil and gas industry is operating with the best interest of citizens in their hearts! These earthquakes MAY be caused by activities of the oil and gas industry, or they MAY be the Sky Fairy telling us to get ready for “Judgment Day!

    With public comments like those made by Mullins it is little wonder people outside Texas think we are all a bunch of backward, hick, uneducated loonies. I am sure it is merely a coincidence that earthquakes are happening in areas where earthquakes have NEVER before been recorded (such as in Dallas and around Cleburne), and then began to occur after gas drilling and disposal well operations began. There could not possibly be a logical link between oil and gas production activities and earthquakes. It is the work of “god!”

    I live in Ohio and only heard about this because most of my family lives around Tyler. Recently we had a rash of earth quakes that were caused by fracking. the gov in Ohio has since stopped the practice due to fears of ground water contamination as well as man made earth quakes! Recently ppl have been finding their wells filling with natural gas! One young man was killed when his blew up! Fracking causes earth quakes companies need to look into this a lot more carefully than they are. Texas wake up! Big business shouldn’t be making the earthquake that’s God’s job! !
