Felt by 41 people across nearby locations.
On March 27, 2022 at 18:35 UTC, a magnitude 4.1 shallow crustal earthquake struck 58 km W of Cartagena, Chile, at a depth of 17.8 km and coordinates -33.5611°, -72.2339°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — 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.
