On January 26, 2022 at 16:36 UTC, a magnitude 5.6 shallow crustal earthquake struck in the Balleny Islands region, at a depth of 10.0 km and coordinates -63.5219°, 170.1107°. 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 5.6 releases seismic energy equivalent to roughly 4 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 4.4 km — a useful intuition for the size of the slip patch on the fault.
