On April 1, 2026 at 23:00 UTC, a magnitude 4.8 intermediate depth earthquake struck 241 km NNE of Hicks Bay, New Zealand, at a depth of 95.7 km and coordinates -35.6171°, 179.4099°. This earthquake was detected by 18 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
