M4.3 Earthquake 57 km SW of Sola, Vanuatu — September 10, 2022
2022-09-10 19:09:02 UTC (2022-09-10) · approx. 6:09 AM UTC+11 local
On September 10, 2022 at 19:09 UTC, a magnitude 4.3 intermediate depth earthquake struck 57 km SW of Sola, Vanuatu, at a depth of 169.7 km and coordinates -14.2233°, 167.1596°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 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 24 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 4.3 earthquake near Sola, Vanuatu?
The magnitude 4.3 earthquake that struck 57 km SW of Sola, Vanuatu on September 10, 2022 at 19:09 UTC had a depth of 169.7 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 4.3 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 4.3 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.
