M4.5 Earthquake near near the coast of Chiapas, Mexico — April 11, 2021
2021-04-11 18:19:16 UTC (2021-04-11) · approx. 12:19 PM UTC-6 local
On April 11, 2021 at 18:19 UTC, a magnitude 4.5 intermediate depth earthquake struck near near the coast of Chiapas, Mexico, at a depth of 99.0 km and coordinates 14.9659°, -92.4933°.
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.
