On October 15, 2026 at 20:25 UTC, a magnitude 4.3 intermediate depth earthquake struck 11 km SE of Huara, Chile, at a depth of 72.2 km and coordinates -20.0692°, -69.6992°.

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.
