On January 9, 2026 at 12:13 UTC, a magnitude 5.1 shallow crustal earthquake struck in the Kermadec Islands region, at a depth of 37.0 km and coordinates -31.2384°, -178.0197°. This earthquake was detected by 60 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
