Part of an active aftershock sequence.Aftershock of the M5.2 mainshock.
On April 16, 2026 at 12:40 UTC, a magnitude 4.8 shallow crustal earthquake struck south of the Kermadec Islands, at a depth of 10.0 km and coordinates -32.1302°, -178.1517°. This earthquake was detected by 32 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Active aftershock sequence: This earthquake is the mainshock of an ongoing aftershock sequence. In the 71 hours since the mainshock, the USGS has recorded 5 aftershocks within 20 km of the epicenter, including 5 of magnitude 3.0 or greater. The strongest aftershock was a magnitude 6.0 event 2 days ago. Aftershock sequences from mainshocks of magnitude 4.8 typically continue for several days and gradually diminish over time, though occasional larger aftershocks remain possible.

Common Questions
How strong was the magnitude 4.8 earthquake south of the Kermadec Islands?
The magnitude 4.8 earthquake that struck south of the Kermadec Islands on April 16, 2026 at 12:40 UTC had a depth of 10.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -32.1302°, -178.1517°, which is south of the Kermadec Islands.
Were there aftershocks?
Yes. In the 71 hours since the mainshock, the USGS has recorded 5 aftershocks within 20 km of the epicenter, including 5 of magnitude 3.0 or greater. Aftershock activity is typical for earthquakes of this magnitude and can continue for several days.
Is this the same earthquake as the M5.2 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier south of the Kermadec Islands. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
