M5.0 Earthquake in the Kermadec Islands region — June 5, 2026
2026-06-05 22:22:02 UTC (2026-06-05) · approx. 10:22 AM UTC-12 local
Aftershock of the M5.6 mainshock.
On June 5, 2026 at 22:22 UTC, a magnitude 5.0 shallow crustal earthquake struck in the Kermadec Islands region, at a depth of 10.0 km and coordinates -29.3309°, -176.8477°. This earthquake was detected by 34 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — 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 3 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.

Common Questions
How strong was the magnitude 5.0 earthquake in the Kermadec Islands region?
The magnitude 5.0 earthquake that struck in the Kermadec Islands region on June 5, 2026 at 22:22 UTC had a depth of 10.0 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at -29.3309°, -176.8477°, which is in the Kermadec Islands region.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.6 one earlier?
No. This magnitude 5.0 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.
