On May 12, 2024 at 11:39 UTC, a magnitude 6.4 shallow crustal earthquake struck 28 km WSW of Brisas Barra de Suchiate, Mexico, at a depth of 61.9 km and coordinates 14.4264°, -92.4617°. The earthquake was reported felt by 158 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.1 (very strong). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 267 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 762, making it a moderate-impact event. The nearest populated place is El Encanto (population 1,726).

Physical scale: An earthquake of magnitude 6.4 releases seismic energy equivalent to roughly 60 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 16 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 6.4 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 6.4 event is significantly smaller than that historical record.
