On March 11, 2022 at 22:58 UTC, a magnitude 4.7 shallow crustal earthquake struck 91 km SE of Mwinilunga, Zambia, at a depth of 10.0 km and coordinates -12.2290°, 25.1039°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
