On October 5, 2024 at 16:08 UTC, a magnitude 5.1 shallow crustal earthquake struck 27 km W of Karori, New Zealand, at a depth of 44.4 km and coordinates -41.2833°, 174.4130°. The earthquake was reported felt by 61 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.2 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 172 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 436, placing it among routine seismic activity. The nearest populated place is Wellington (population 381,900).

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.

Where did the earthquake occur?

The earthquake epicenter was located at -41.2833°, 174.4130°, which is 27 km W of Karori, New Zealand. The nearest populated place is Wellington (population 381,900). View all earthquakes in New Zealand.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks 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 5.1 event is significantly smaller than that historical record.
