2022-10-30 18:17:10 UTC (2022-10-30) · approx. 12:17 PM UTC-6 local
On October 30, 2022 at 18:17 UTC, a magnitude 4.5 shallow crustal earthquake struck 108 km SW of La Esperanza (El Zapotal), Mexico, at a depth of 35.0 km and coordinates 14.6750°, -93.7781°. This earthquake was detected by 29 seismic stations with good 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.
