M4.4 Earthquake 67 km N of Port-Olry, Vanuatu — September 5, 2026
2026-09-05 12:55:05 UTC (1 hour ago) · approx. 11:55 PM UTC+11 local
On September 5, 2026 at 12:55 UTC, a magnitude 4.4 intermediate depth earthquake struck 67 km N of Port-Olry, Vanuatu, at a depth of 166.3 km and coordinates -14.4350°, 167.1398°.
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 6.1 mainshock that occurred 20 days ago 55 km NNE of Port-Olry, Vanuatu. Since the mainshock, the USGS has recorded 3 aftershocks in this area. Aftershock activity is expected to continue for weeks to months as stresses on surrounding faults redistribute.

Common Questions
How strong was the magnitude 4.4 earthquake near Port-Olry, Vanuatu?
The magnitude 4.4 earthquake that struck 67 km N of Port-Olry, Vanuatu on September 5, 2026 at 12:55 UTC had a depth of 166.3 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 M6.1 one earlier?
No. This magnitude 4.4 earthquake is an aftershock of the larger magnitude 6.1 mainshock that occurred earlier 55 km NNE of Port-Olry, Vanuatu. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
