On May 10, 2023 at 19:45 UTC, a magnitude 4.3 intermediate depth earthquake struck 75 km E of Taltal, Chile, at a depth of 74.8 km and coordinates -25.3931°, -69.7335°.
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.
