On June 30, 2025 at 19:30 UTC, a magnitude 4.1 intermediate depth earthquake struck 8 km ENE of Llaillay, Chile, at a depth of 78.4 km and coordinates -32.8172°, -70.8678°.

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.
