M4.4 Earthquake 122 km SE of Kokopo, Papua New Guinea — November 6, 2025
2025-11-06 22:14:23 UTC (2025-11-06) · approx. 8:14 AM UTC+10 local
On November 6, 2025 at 22:14 UTC, a magnitude 4.4 shallow crustal earthquake struck 122 km SE of Kokopo, Papua New Guinea, at a depth of 59.4 km and coordinates -4.9790°, 153.1751°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 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 5.0 mainshock that occurred 11 hours ago 104 km ESE of Kokopo, Papua New Guinea. Since the mainshock, the USGS has recorded 0 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 4.4 earthquake near Kokopo, Papua New Guinea?
The magnitude 4.4 earthquake that struck 122 km SE of Kokopo, Papua New Guinea on November 6, 2025 at 22:14 UTC had a depth of 59.4 km. For context, this was a light earthquake commonly felt near the epicenter.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.0 one earlier?
No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 104 km ESE of Kokopo, Papua New Guinea. 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.
