On May 13, 2026 at 13:55 UTC, a magnitude 4.3 intermediate depth earthquake struck 82 km E of La Tirana, Chile, at a depth of 110.7 km and coordinates -20.3552°, -68.8668°.

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.
