Texas has recorded over 4,400 earthquakes since 1900, with the majority being small. The strongest quake, a magnitude 5.8, occurred in 1931 near Valentine. Recent data shows a significant increase in seismic activity, particularly due to human activities such as fracking.
- 01Texas has experienced more than 4,400 earthquakes since 1900, primarily small in magnitude.
- 02The largest recorded earthquake was a magnitude 5.8 on August 16, 1931, near Valentine, Presidio County.
- 03Clusters of earthquakes are prevalent in West Texas, an area with numerous fault zones and fracking activities.
- 04Induced seismicity, caused by human activities like fracking and mining, has contributed to recent earthquake occurrences.
- 05Since 2020, 85% of Texas earthquakes with a magnitude of 2.5 or greater have occurred, with a peak of 1,083 in 2022.

Texas is not typically associated with earthquakes, yet over 4,400 have been recorded in the state since 1900, according to the U.S. Geological Survey (USGS). Most of these earthquakes are minor, but 90 have reached a magnitude of 4 or higher, with the strongest being a magnitude 5.8 quake that struck near Valentine, Presidio County, on August 16, 1931. The USGS has mapped earthquakes of magnitude 2.5 and above, revealing that while seismic activity occurs statewide, clusters are particularly common in West Texas, which is home to many fault zones and is known for fracking. This hydraulic fracturing process, along with mining and dam construction, has been linked to induced seismicity, where human activities trigger earthquakes. Recent trends indicate a sharp rise in earthquake reports, peaking at 1,083 in 2022, although this number has since declined to 625 in 2025. Notably, 85% of all earthquakes in Texas of magnitude 2.5 or greater have occurred since the beginning of 2020.
