On August 26, 2026 at 22:23 UTC, a magnitude 4.2 intermediate depth earthquake struck 22 km NE of Talca, Chile, at a depth of 78.8 km and coordinates -35.3132°, -71.4564°.
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.
