M5.1 Earthquake 17 km NNE of Hermleigh, Texas — July 26, 2024
2024-07-26 14:28:29 UTC (2024-07-26) · approx. 7:28 AM UTC-7 local
Felt by 2,607 people across a wide area. Maximum shaking intensity MMI 6.0 (very strong).
On July 26, 2024 at 14:28 UTC, a magnitude 5.1 shallow crustal earthquake struck 17 km NNE of Hermleigh, Texas, at a depth of 3.3 km and coordinates 32.7660°, -100.6590°. The earthquake was reported felt by 2,607 peopleacross a wide area, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.0 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 38 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 1010, making it one of the most significant global earthquakes in recent days. The nearest populated place is Rotan (population 1,508).
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Texas, a region characterized by a mix of natural intraplate seismicity and induced events in the Permian Basin linked to wastewater disposal. View all earthquakes in Texas.

What the Shaking Felt Like
At MMI 6.0 (very strong), people in the most strongly affected areas would have experienced: Strong shaking felt by everyone. Heavy furniture may move. Books fall from shelves. Plaster and chimneys may crack. Damage is generally slight in well-built structures.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.
Has Texas had earthquakes this big before?
The largest recorded earthquake in Texas was the M5.8 Valentine earthquake of August 16, 1931. Today's magnitude 5.1 event is within one magnitude unit of that historical record.
