On July 11, 2024 at 17:55 UTC, a magnitude 4.2 shallow crustal earthquake struck 53 km SW of Atiquipa, Peru, at a depth of 24.7 km and coordinates -16.1427°, -74.7109°.
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.
