On June 4, 2026 at 21:59 UTC, a magnitude 4.1 intermediate depth earthquake struck 87 km ESE of La Tirana, Chile, at a depth of 97.2 km and coordinates -20.6457°, -68.8845°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
