M4.9 Earthquake 35 km ESE of Luganville, Vanuatu — February 10, 2026
2026-02-10 20:02:59 UTC (2026-02-10) · approx. 7:02 AM UTC+11 local
Aftershock of the M5.0 mainshock.
On February 10, 2026 at 20:02 UTC, a magnitude 4.9 intermediate depth earthquake struck 35 km ESE of Luganville, Vanuatu, at a depth of 121.6 km and coordinates -15.6146°, 167.4824°. This earthquake was detected by 59 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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 5.0 mainshock that occurred 21 days ago 32 km ENE of Luganville, Vanuatu. 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.
The epicenter is located in Vanuatu, a region characterized by the New Hebrides subduction zone, where the Australian Plate subducts eastward at approximately 90 mm per year. View all earthquakes in Vanuatu.

Common Questions
How strong was the magnitude 4.9 earthquake near Luganville, Vanuatu?
The magnitude 4.9 earthquake that struck 35 km ESE of Luganville, Vanuatu on February 10, 2026 at 20:02 UTC had a depth of 121.6 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -15.6146°, 167.4824°, which is 35 km ESE of Luganville, Vanuatu. View all earthquakes in Vanuatu.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 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 4.9 earthquake is an aftershock of the larger magnitude 5.0 mainshock that occurred earlier 32 km ENE of Luganville, Vanuatu. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
Has Vanuatu had earthquakes this big before?
The largest recorded earthquake in Vanuatu was the M7.9 Vanuatu earthquake of October 7, 2009. Today's magnitude 4.9 event is significantly smaller than that historical record.
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.
