M5.1 Earthquake 42 km W of Coquimbo, Chile — February 27, 2022
2022-02-27 20:49:47 UTC (2022-02-27) · approx. 3:49 PM UTC-5 local
On February 27, 2022 at 20:49 UTC, a magnitude 5.1 shallow crustal earthquake struck 42 km W of Coquimbo, Chile, at a depth of 27.2 km and coordinates -29.8884°, -71.7733°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Chile, a region characterized by the Peru-Chile Trench, where the Nazca Plate subducts beneath South America at 65-80 mm per year. The nearest mapped fault system is the Peru-Chile Trench. View all earthquakes in Chile.
