On June 5, 2023 at 21:33 UTC, a magnitude 4.3 intermediate depth earthquake struck 73 km N of Tocopilla, Chile, at a depth of 78.5 km and coordinates -21.4430°, -70.0735°.
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.
