On February 2, 2022 at 19:23 UTC, a magnitude 5.3 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 66.3 km and coordinates -32.2383°, -179.0992°. 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.
