A magnitude 6.0 earthquake struck the ocean floor about 186 kilometers northwest of Port-Olry, Vanuatu, at a shallow depth of roughly 10 kilometers, according to the US Geological Survey. The epicenter is offshore in the northern Vanuatu island chain, a seismically active region where tectonic plates meet along the Pacific ‘Ring of Fire.’
Because of the distance from population centers, the risk of serious damage is low. The nearest major town, Port Vila (population around 50,000), is roughly 497 kilometers away — far enough that shaking there, if felt at all, would be mild. Communities on Vanuatu’s northern islands, such as Espiritu Santo, may have felt moderate shaking, and residents should be alert for fallen objects or minor damage to older or unreinforced buildings.
This region is no stranger to earthquakes: this is at least the 30th magnitude 5.0 or greater quake recorded within about 300 kilometers of this location in the past year. That level of activity is normal for this tectonic boundary, but it does mean aftershocks are a realistic possibility in the coming hours and days.
What to Watch For
Aftershocks: Quakes of magnitude 5 or higher often follow an event like this. If you’re in the northern Vanuatu islands and feel shaking, drop, cover, and hold on — and stay away from damaged structures afterward.
Tsunami potential: A magnitude 6.0 offshore quake at 10 km depth is generally below the threshold for a dangerous tsunami, but coastal residents should still monitor local alerts from Vanuatu’s disaster management office, especially if strong or long-lasting shaking is felt.
Basic readiness: If you live in Vanuatu’s northern islands, secure heavy furniture, keep a flashlight and water handy, and know your evacuation route to higher ground — standard practice in one of the world’s most earthquake-prone nations.
Data for this alert comes from the US Geological Survey (USGS) earthquake monitoring network.
Frequently Asked Questions
Was the earthquake felt in Port Vila?
Port Vila is about 497 km from the epicenter, so any shaking there would have been light or unnoticeable. Stronger shaking was possible on the northern islands closer to the epicenter, such as Espiritu Santo.
Is a tsunami possible from this earthquake?
A magnitude 6.0 quake at 10 km depth is generally too small to generate a destructive tsunami, and no tsunami threat has been indicated. Coastal residents should still follow guidance from local authorities if strong shaking is felt.
Are aftershocks likely?
Yes. Earthquakes of this size are typically followed by smaller aftershocks over hours to days, and this part of Vanuatu is highly active — at least 30 quakes of magnitude 5.0+ have occurred within 300 km of this spot in the past year.
Should I be worried about damage or injuries?
The epicenter is offshore and far from major population centers, so significant damage is unlikely. Minor shaking damage to vulnerable buildings on nearby northern islands is possible, and residents should check structures before re-entering.

Reported Impact
USGS’s automated PAGER system currently estimates a Green alert level (minimal expected casualties or damage).
Impact figures are from USGS as of when this alert was generated and can rise as more reports come in – this is not a final damage assessment.
