M4.5 Earthquake near Kermadec Islands, New Zealand — November 13, 2024
2024-11-13 16:51:09 UTC (2024-11-13) · approx. 4:51 AM UTC-12 local
Aftershock of the M5.6 mainshock.
On November 13, 2024 at 16:51 UTC, a magnitude 4.5 shallow crustal earthquake struck near Kermadec Islands, New Zealand, at a depth of 54.4 km and coordinates -29.8593°, -177.2971°. This earthquake was detected by 19 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.6 mainshock that occurred 14 days ago in the Kermadec Islands region. Since the mainshock, the USGS has recorded 2 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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.

Common Questions
How strong was the magnitude 4.5 earthquake near Kermadec Islands, New Zealand?
The magnitude 4.5 earthquake that struck near Kermadec Islands, New Zealand on November 13, 2024 at 16:51 UTC had a depth of 54.4 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -29.8593°, -177.2971°, which is near Kermadec Islands, New Zealand. View all earthquakes in New Zealand.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.5 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.6 one earlier?
No. This magnitude 4.5 earthquake is an aftershock of the larger magnitude 5.6 mainshock that occurred earlier in the Kermadec Islands region. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 4.5 event is significantly smaller than that historical record.
