On May 10, 2023 at 08:45 UTC, a magnitude 4.9 shallow crustal earthquake struck 50 km SW of Campo Pesquero el Colorado, Mexico, at a depth of 10.0 km and coordinates 25.4406°, -109.6761°. This earthquake was detected by 172 seismic stations with good location accuracy and was assigned a USGS significance rating of 370, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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 Colorado.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 earthquakes can continue for several days 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 4.9 event is significantly smaller than that historical record.
