M5.9 Earthquake 240 km SW of La Cruz de Loreto, Mexico — May 13, 2025
2025-05-13 20:43:04 UTC (2025-05-13) · approx. 1:43 PM UTC-7 local
Felt by 6 people across nearby locations.
On May 13, 2025 at 20:43 UTC, a magnitude 5.9 shallow crustal earthquake struck 240 km SW of La Cruz de Loreto, Mexico, at a depth of 11.9 km and coordinates 18.6822°, -107.2678°. The earthquake was reported felt by 6 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.5 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 136 seismic stations with good location accuracy and was assigned a USGS significance rating of 537, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 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 5.9 earthquakes can continue for days to weeks 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 5.9 event is significantly smaller than that historical record.
