2025-06-16 21:38:25 UTC (2025-06-16) · approx. 3:38 PM UTC-6 local
On June 16, 2025 at 21:38 UTC, a magnitude 4.9 shallow crustal earthquake struck 79 km S of San Mateo del Mar, Mexico, at a depth of 38.7 km and coordinates 15.4975°, -94.8874°. This earthquake was detected by 62 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, 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 Mexico.
