On February 27, 2026 at 18:55 UTC, a magnitude 4.2 intermediate depth earthquake struck 11 km ENE of Orcopampa, Peru, at a depth of 154.1 km and coordinates -15.2109°, -72.2522°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
