M4.0 Earthquake 39 km WSW of Mentone, Texas — November 16, 2022
2022-11-16 22:39:13 UTC (2022-11-16) · approx. 3:39 PM UTC-7 local
Felt by 46 people across nearby locations. Maximum shaking intensity MMI 4.4 (moderate).
On November 16, 2022 at 22:39 UTC, a magnitude 4.0 shallow crustal earthquake struck 39 km WSW of Mentone, Texas, at a depth of 8.1 km and coordinates 31.6295°, -104.0091°. The earthquake was reported felt by 46 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.4 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 65 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 271, placing it among routine seismic activity. The nearest populated place is Pecos (population 8,780).
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.0 earthquakes can continue for several days 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 4.0 event is significantly smaller than that historical record.
