Felt by 1 person across nearby locations.
On November 20, 2022 at 23:36 UTC, a magnitude 4.8 shallow crustal earthquake struck 184 km SW of José María Morelos, Mexico, at a depth of 10.0 km and coordinates 18.5786°, -106.5050°. This earthquake was detected by 96 seismic stations with good location accuracy and was assigned a USGS significance rating of 355, 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.
