On June 20, 2026 at 01:32 UTC, a magnitude 4.2 intermediate depth earthquake struck 13 km SSE of Llaillay, Chile, at a depth of 80.4 km and coordinates -32.9534°, -70.9171°.
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.
