On February 12, 2024 at 23:25 UTC, a magnitude 4.0 shallow crustal earthquake struck 82 km S of Pacocha, Peru, at a depth of 25.7 km and coordinates -18.3843°, -71.4353°.

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
