2020-07-12 15:09:37 UTC (2020-07-12) · approx. 8:09 AM UTC-7 local
On July 12, 2020 at 15:09 UTC, a magnitude 4.7 shallow crustal earthquake struck 182 km SSW of Barra de Navidad, Mexico, at a depth of 10.0 km and coordinates 17.7107°, -105.3970°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
