On May 28, 2025 at 23:19 UTC, a magnitude 4.4 intermediate depth earthquake struck 14 km S of Lluta, Peru, at a depth of 116.0 km and coordinates -16.1467°, -72.0309°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
