Recent Earthquake Activity in West Texas Raises Concerns
West Texas has been rattled by a series of earthquakes over the past 24 hours, prompting concerns about increased seismic activity in the region. The most significant tremor, registering a 3.3 magnitude, occurred recently. This follows several smaller seismic events, raising questions about the potential link to oil and gas operations in the area, a major producer of crude oil.
3.3 Magnitude Earthquake Latest in String of Tremors
The United States Geological Survey (USGS) reported the 3.3 magnitude earthquake at 9:01 AM Eastern Time (ET). The epicenter was located in western Texas, approximately 19 miles from Mentone. This event followed a 2.3 magnitude earthquake that struck the same area roughly two hours prior, indicating a cluster of seismic events in a short period.
Minor Tremors Detected in the Region
While earthquakes above magnitude 2.5 are often perceptible and capable of causing minor damage, there have been no reports of damage or injuries from the 3.3 magnitude event. The USGS has recorded an estimated ten minor tremors in the West Texas region over the last day, ranging in magnitude from 1.7 to 2.4. This persistent low-level seismic activity underlines the ongoing geological shifts in the area.
Possible Link to Oil and Gas Extraction
Although West Texas has known fault lines, the recent increase in earthquake frequency is suspected to be linked to induced seismicity. This phenomenon refers to earthquakes triggered by human actions, particularly the extensive oil and gas extraction activities prevalent in the region.
Wastewater injection, a common practice in oil and gas operations, is often cited as a primary cause of these induced earthquakes. Injecting wastewater deep underground can elevate pressure and lubricate geological faults, making them more prone to slippage and subsequent seismic events.

Texas’ Role in Oil Production and Fracking
Texas is a major contributor to the nation’s energy sector, accounting for approximately 42 percent of US crude oil production, solidifying its position as the largest producer in the country. The state is also characterized by the widespread practice of fracking, a method used to extract oil and gas from deep rock formations.
Fracking involves injecting substantial volumes of water, chemicals, and sand at high pressure into rock formations to create fractures and release trapped fuels. While fracking itself is not typically the direct cause of earthquakes, the disposal of wastewater generated during the fracking process is strongly linked to triggering seismic activity.
Research Links Seismic Activity to Oil and Gas Production
A 2022 study conducted by the University of Texas at Austin indicated a strong correlation between oil and gas production and earthquake activity. The research concluded that 68 percent of Texas earthquakes exceeding magnitude 1.5 were “highly associated” with these industrial operations.
Dr. Alexandros Savvaidis recently commented on the potential for increased drilling to exacerbate seismic risks in Texas. He noted to KMID that “Deep injection wells, in particular, are linked to higher-magnitude earthquakes,” while “shallower injections seem to be less hazardous in terms of large seismic events.”
Recent Seismic Data in Texas
Recent data reveals a significant number of seismic events in Texas. Records indicate 406 earthquakes in the preceding 30 days and 79 earthquakes in the last seven days. This elevated frequency of earthquakes is a point of concern for seismologists and residents alike.

Historical Earthquake Data in Texas
The most powerful earthquake ever recorded in Texas was a 6.0 magnitude event in Valentine, Jeff Davis County, on August 16, 1931. Historical accounts reported that the tremors were felt as far east as Taylor, north of Austin, and as far south as San Antonio. On that day, a series of seven notable tremors shook the region, with some lasting up to 72 seconds. This earthquake sequence began in the early morning and persisted into the early afternoon.
More recently, West Texas experienced a 5.0 magnitude earthquake this past February, near the Culberson and Reeves counties border. The USGS estimated that approximately 950,000 people felt weak to light shaking from this event, demonstrating the widespread impact of even moderate earthquakes in the region.
