On February 28, 2024 at 16:18 UTC, a magnitude 4.2 shallow crustal earthquake struck 10 km ESE of Maoribank, New Zealand, at a depth of 30.3 km and coordinates -41.1531°, 175.2067°. This earthquake was detected by 26 seismic stations with good location accuracy and was assigned a USGS significance rating of 281, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.2 earthquakes can continue for several days and gradually diminish over time.

Has New Zealand had earthquakes this big before?

The largest recorded earthquake in New Zealand was the M8.2 Wairarapa earthquake of January 23, 1855. Today's magnitude 4.2 event is significantly smaller than that historical record.
