On May 16, 2026 at 17:59 UTC, a magnitude 4.4 shallow crustal earthquake struck 48 km S of Tocopilla, Chile, at a depth of 39.2 km and coordinates -22.5246°, -70.2840°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
