2026-07-24 17:33:33 UTC (2026-07-24) · approx. 11:33 AM UTC-6 local
On July 24, 2026 at 17:33 UTC, a magnitude 4.5 intermediate depth earthquake struck 26 km SSW of Las Choapas, Mexico, at a depth of 183.5 km and coordinates 17.6913°, -94.2042°. This earthquake was detected by 45 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.
