On May 29, 2025 at 19:26 UTC, a magnitude 3.5 shallow crustal earthquake struck 5 km WSW of Puerto, Chile, at a depth of 42.7 km and coordinates -20.2359°, -70.1992°.

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
