M5.3 Earthquake south of the Kermadec Islands — March 10, 2026
2026-03-10 23:51:16 UTC (2026-03-10) · approx. 11:51 AM UTC-12 local
Maximum shaking intensity MMI 5.7 (strong).
On March 10, 2026 at 23:51 UTC, a magnitude 5.3 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 10.0 km and coordinates -32.9307°, -178.4117°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 102 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
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.
