2026-10-02 06:53:35 UTC (2 hours ago) · approx. 11:53 PM UTC-7 local
On October 2, 2026 at 06:53 UTC, a magnitude 4.8 shallow crustal earthquake struck 35 km SSW of El Colomo, Mexico, at a depth of 24.0 km and coordinates 18.7561°, -104.3753°. This earthquake was detected by 57 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
