On June 16, 2025 at 23:47 UTC, a magnitude 3.7 shallow crustal earthquake struck 48 km S of La Tirana, Chile, at a depth of 49.4 km and coordinates -20.7698°, -69.7412°.

Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
