M4.6 Earthquake 73 km ENE of Mulegé, Mexico — September 24, 2020
2020-09-24 23:06:42 UTC (2020-09-24) · approx. 4:06 PM UTC-7 local
On September 24, 2020 at 23:06 UTC, a magnitude 4.6 shallow crustal earthquake struck 73 km ENE of Mulegé, Mexico, at a depth of 10.0 km and coordinates 27.0779°, -111.2685°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 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.
