On November 22, 2022 at 16:39 UTC, a magnitude 6.2 shallow crustal earthquake struck 28 km SW of Las Brisas, Mexico, at a depth of 10.0 km and coordinates 30.7936°, -116.3907°. The earthquake was reported felt by 438 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.6 (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 164 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 889, making it one of the more significant events of the week. The nearest populated place is La Providencia (population 1,253).

Physical scale: An earthquake of magnitude 6.2 releases seismic energy equivalent to roughly 30 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 11 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Mexico, a region characterized by the Middle America Trench, where the Cocos Plate subducts beneath the North American Plate. The nearest mapped fault system is the Middle America Trench. View all earthquakes in Mexico.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 6.2 earthquakes can continue for weeks to months and gradually diminish over time.

Has Mexico had earthquakes this big before?

The largest recorded earthquake in Mexico was the M8.1 Chiapas earthquake of September 8, 2017. Today's magnitude 6.2 event is significantly smaller than that historical record.
