2024-08-05 20:35:25 UTC (2024-08-05) · approx. 2:35 PM UTC-6 local
On August 5, 2024 at 20:35 UTC, a magnitude 4.9 shallow crustal earthquake struck 66 km WSW of Puerto Madero, Mexico, at a depth of 64.0 km and coordinates 14.4823°, -92.9875°. This earthquake was detected by 120 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.
