2026-02-04 10:39:28 UTC (2026-02-04) · approx. 10:39 PM UTC-12 local
On February 4, 2026 at 10:39 UTC, a magnitude 6.1 intermediate depth earthquake struck near Kermadec Islands, New Zealand, at a depth of 167.0 km and coordinates -29.5260°, -178.5970°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 249 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 572, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 6.1 releases seismic energy equivalent to roughly 21 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 9.7 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in New Zealand, a region characterized by the Hikurangi subduction zone in the North Island and the Alpine Fault in the South Island. The nearest mapped fault system is the Alpine Fault. View all earthquakes in New Zealand.
