On March 13, 2022 at 22:07 UTC, a magnitude 4.7 shallow crustal earthquake struck 14 km W of eMbalenhle, South Africa, at a depth of 5.0 km and coordinates -26.5139°, 28.9243°.

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.
