On April 14, 2022 at 22:17 UTC, a magnitude 4.7 shallow crustal earthquake struck 36 km NNW of La Ligua, Chile, at a depth of 43.5 km and coordinates -32.1762°, -71.4480°.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.

Has Chile had earthquakes this big before?

The largest recorded earthquake in Chile was the M9.5 Great Chilean earthquake of May 22, 1960. Today's magnitude 4.7 event is significantly smaller than that historical record.
