The Balcones Fault is in one of the lowest-risk zones for earthquakes in the United States. [ 6 ] The surface expression of the fault is the Balcones Escarpment, [ 7 ] which forms the eastern boundary of the Texas Hill Country and the western boundary of the Texas Coastal Plain, and consists of cliffs and cliff-like structures.
The earthquakes in this area primarily occur on buried faults between the Amarillo Uplift and the Anadarko Basin. [3]: 24 An earthquake with a magnitude of 5.5–6.0 is expected to occur every 50–100 years in the Texas Panhandle, while an earthquake with a magnitude greater than 6.0 is expected to occur every 300 years.

The various faults are characterized as normal faults, meaning that the downthrown side is in the direction of the dip of the fault plane. This fault system as well as others located in nearby parts of Texas are believed to have formed millions of years ago during the formation of the Gulf of Mexico. No significant earthquakes have occurred on ...
The Railroad Commission Texas, which regulates the state’s oil and gas industry, is investigating a 5.4-magnitude earthquake that rocked communities in West Texas last Wednesday, The Texas ...
The Texas Railroad Commission cited seven earthquakes in the area between Nov. 8 and Dec. 17, 2023 ranging in magnitude from 3.6 to 5.2 – a quake reported Nov. 8 near Coalson Draw, Texas that ...
Earthquakes in the New Madrid and Wabash Valley seismic zones from 1974 to 2002, with magnitudes larger than 2.5. The zone had four of the largest earthquakes in recorded North American history, with moment magnitudes estimated to be as large as 7 or greater, all occurring within a 3-month period between December 1811 and February 1812. Many of ...
The Railroad Commission of Texas is investigating the 5.1-magnitude earthquake that rattled much of West Texas Monday night.
Its epicenter was near the town of Valentine, Texas; there, the earthquake caused damage to many homes and buildings. [6] The earthquake may have been caused by movement along oblique-slip faulting in West Texas, the most seismically active region in the state. Shaking from the earthquake was perceptible within a 400 mi (640 km) radius of the ...
