On July 2, 2026 at 16:35 UTC, a magnitude 4.2 shallow crustal earthquake struck 63 km NNW of Ancud, Chile, at a depth of 50.3 km and coordinates -41.3865°, -74.2211°.
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.
