On June 10, 2021 at 16:43 UTC, a magnitude 4.3 shallow crustal earthquake struck 53 km N of Vallenar, Chile, at a depth of 50.1 km and coordinates -28.0931°, -70.7779°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
