2026-09-28 06:37:56 UTC (2 hours ago) · approx. 6:37 PM UTC+12 local
On September 28, 2026 at 06:37 UTC, a magnitude 4.7 shallow crustal earthquake struck 149 km NE of Hicks Bay, New Zealand, at a depth of 10.0 km and coordinates -36.8177°, 179.6666°. This earthquake was detected by 29 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
