On May 7, 2023 at 06:29 UTC, a magnitude 5.2 shallow crustal earthquake struck 6 km NNW of Taltal, Chile, at a depth of 45.6 km and coordinates -25.3542°, -70.5138°. This earthquake was detected by 95 seismic stations with good location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
