On August 21, 2024 at 19:05 UTC, a magnitude 4.2 intermediate depth earthquake struck 7 km WSW of Yanaca, Peru, at a depth of 76.7 km and coordinates -14.2394°, -73.2243°.
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.
