On July 2, 2023 at 23:17 UTC, a magnitude 4.4 intermediate depth earthquake struck 50 km ESE of Palca, Peru, at a depth of 147.6 km and coordinates -18.0206°, -69.5537°.
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.
