On January 19, 2022 at 05:46 UTC, a magnitude 5.3 shallow crustal earthquake struck southwest of Africa, at a depth of 10.0 km and coordinates -52.4599°, 12.9763°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.

Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
