On February 16, 2026 at 22:34 UTC, a magnitude 4.2 intermediate depth earthquake struck 39 km E of La Tirana, Chile, at a depth of 111.9 km and coordinates -20.3554°, -69.2748°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
