On September 5, 2022 at 07:50 UTC, a magnitude 4.9 shallow crustal earthquake struck 59 km WNW of Cartagena, Chile, at a depth of 17.0 km and coordinates -33.4420°, -72.2334°. This earthquake was detected by 129 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 373, placing it among routine seismic activity.

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 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.
