On May 25, 2023 at 20:20 UTC, a magnitude 4.4 intermediate depth earthquake struck 13 km NE of Palca, Peru, at a depth of 126.6 km and coordinates -17.6963°, -69.8612°.
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.
