Notable Earthquakes Shake Texas on Occasion
Texas has experienced more than 100 earthquakes of magnitude 3 or greater since 1847. However, because the density of both seismographs and people has been very low in Texas, knowledge of the state’s seismicity is undoubtedly incomplete.
The largest known earthquake in Texas occurred on Aug. 16, 1931, near the town of Valentine in Jeff Davis County. The total felt area exceeded one million square kilometers (about 400,000 square miles).
Ten earthquakes had epicenters near El Paso. Several of these shocks have produced minor damage. One earthquake on March 7, 1923, caused an adobe house to collapse and led to the suffocation of a man in Juarez, Mex. This is the only known death caused by a Texas earthquake. Seismic activity in this area of Texas may be related to known faults that have been interpreted as part of the Rio Grande rift zone, a zone of crustal extension.
Notable earthquakes in the Texas Panhandle are probably associated with an ancient zone of crustal weakness that has been reactivated in recent times. Although the largest known earthquakes in the Panhandle have not exceeded magnitude 5.4, the potential for very large earthquakes remains uncertain.
Historic earthquakes in East and Central Texas include the 1847 Seguin, 1873 Manor, 1887 Paige, 1902 Creedmoor, 1932 Mexia-Wortham and the 1934 quake near Paris. These earthquakes were all fairly small and probably occurred as a result of sediment loading and resulting flexure in the Gulf of Mexico.
Earthquakes also have been located in Southeast Texas. The 1887 Wellborn, 1910 Hempstead and 1914 Anderson shocks may have been related to salt dome growth or minor adjustments from sediment loading in the Gulf. The 1891 Rusk and the 1981 Center and Jacksonville earthquakes in Northeast Texas were all located on or near an 80-kilometer segment of the Mount Enterprise fault system.
Fluid withdrawal is usually associated with aseismic subsidence and faulting such as occurs in the Houston area. However, small earthquakes are sometimes reported. In 1925, small shocks were associated with subsidence produced from oil production at the Goose Creek old field near Houston.
Larger earthquakes in East Texas also may have resulted from fluid withdrawal. Tentative relations between withdrawal and seismicity have been proposed for the 1932 Mexia-Wortham and the 1957 Gladewater earthquakes. More convincing evidence exists for the earthquakes in some oil and gas fields in South Texas.
The injection of fluids into the earth’s crust for disposal or for secondary recovery of oil also has been known to produce earthquakes in other states. Some earthquakes, none very damaging, may be associated with fluid injection in the Permian Basin of West Texas.
An account of Texas’ seismicity would not be complete without considering the effects of earthquakes from neighboring regions. Popular legend holds that the New Madrid, Mo., earthquakes of 1811-1812 were responsible for the formation of Caddo Lake. However, there exist accounts of the lake’s existence as a swampy area as early as 1722. Whether the shocks deepened the lake is not known. In any case, it is likely that moderately high intensities of shock waves were experienced in Northeast Texas.
The Sonora, Mexico, earthquake of 1887 cracked several buildings in El Paso and caused a general panic in the population of that city. Seismic surface waves from the Alaskan earthquake of 1964 damaged a water well in the Texas Panhandle and produced waves, which damaged several boats in channels along the Gulf Coast

Significant Earthquakes in Texas
Listed chronologically are the significant earthquakes in Texas (above 3.0), followed by the magnitude (commonly called the Richter scale) and known details about each earthquake.
1811 (8.1) — The first of this series of earthquakes at New Madrid, Mo., occurred on Dec. 16, 1811, magnitude 8.1. The second occurred on Jan. 12, 1812, with a magnitude of 7.8, and the third occurred on Feb. 7, 1812, with a magnitude of 8.0. All three were felt over an area of 5,000,000 square kilometers and were probably felt in Texas, but no verifiable accounts are known.

1923 (4.7) — An earthquake on March 7, 1923, caused an adobe house to collapse and led to the suffocation of a man in Juarez, Mex., a few miles from the Texas border. This is the only known death caused by a Texas earthquake.
1925 (5.4) — Another disturbance occurred at Panhandle on July 30, 1925. There were three distinct shocks over a period of 15 seconds. Major problems were the shaking of dishes on shelves and rattling and creaking of furniture. The shocks were felt over an area of approximately 518,000 square kilometers including Roswell, N.M., Tulsa, Okla., and Leavenworth, Kan.
1931 (6.0) — This West Texas earthquake heavily damaged buildings in Valentine. The first shock occurred at 5:40 a.m. on Aug. 16. Although people were panic stricken, there were no fatalities and only a few minor injuries from falling adobe. Even though Valentine bore the brunt of the shock, damage was reported from widely scattered points in Brewster, Culberson, Jeff Davis and Presidio counties. Cracked walls and damaged chimneys were reported from several towns. The total felt area covered about 1,000,000 square kilometers in Texas, New Mexico and Mexico. The earthquake was accompanied by rumbling subterranean sounds heard over practically the entire affected area. The shock was strongly recorded on all seismographs in North America and at stations all over the world. Numerous aftershocks were felt in the epicentral region; the strongest, on Aug. 18, was magnitude 4.2 at Alpine, Lobo, Pecos and Valentine. A minor aftershock was felt at Valentine on Nov. 3.
1932 (4.0) — Slight damage resulted from an earthquake in the Mexia-Wortham area on April 9, 1932. Loose bricks were thrown down and some plaster cracked. The shock was also felt in Coolidge, Currie, Groesbeck, Hillsboro, Teague and Richland.
1934 (4.2) — A moderate earthquake affected an area of about 7,700 square kilometers in northeastern Texas near Paris and an adjoining portion of Oklahoma on April 11, 1934. The tremor was most distinctly felt at Arthur City, Chicota and Powderly. Many persons who felt the shock reported having heard a roaring or rumbling noise. Two shocks were recognized by many observers.
