On June 23, 2020 at 01:17 UTC, a magnitude 4.9 shallow crustal earthquake struck 10 km SSE of Asunción Tlacolulita, Mexico, at a depth of 35.0 km and coordinates 16.2080°, -95.6869°.

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.
