M6.6 Earthquake Strikes Near Norsup, Vanuatu — Shallow Quake in Active Seismic Zone

A magnitude 6.6 earthquake struck about 105 kilometers (65 miles) northeast of Norsup, Vanuatu, according to the U.S. Geological Survey. The quake occurred at a shallow depth of roughly 10 kilometers (6 miles), which means the shaking energy had less ground to travel through before reaching the surface — shallow quakes of this size are often felt strongly and can damage vulnerable buildings near the epicenter.

Norsup sits on the island of Malakula in northern Vanuatu, an island nation in the South Pacific that lies along one of the most seismically active zones on Earth, where tectonic plates grind against each other. This is at least the 28th earthquake of magnitude 5.0 or greater recorded within about 300 kilometers of this spot in the past year, so strong shaking is a familiar reality for residents.

The nearest major population center is Port Vila, the capital, roughly 250 kilometers (155 miles) away with about 50,000 residents. At that distance, shaking would likely be felt as light to moderate but is not expected to cause significant damage. Communities on Malakula and nearby islands closer to the epicenter face the highest risk of structural damage, falling objects, and possible localized disruption to roads and power.

What to watch for

Tsunami potential: Shallow offshore earthquakes of this magnitude can generate local tsunamis. Anyone in coastal areas of Vanuatu should move to higher ground if shaking was strong or prolonged, and monitor official tsunami warnings.

Aftershocks: Quakes of magnitude 5 or higher are likely in the coming hours and days. Treat any damaged building as unsafe until inspected.

Damage reports: Information from remote islands can take hours to arrive. Expect updates on injuries, damage, and any tsunami observations as assessments come in.

This report is based on earthquake data from the U.S. Geological Survey (USGS).

Frequently Asked Questions

Was the earthquake felt in Port Vila?
Port Vila is about 250 km from the epicenter, so residents there may have felt light to moderate shaking, but significant damage in the capital is not expected. The strongest shaking was concentrated near Malakula and surrounding northern islands.

Is a tsunami possible from this quake?
Yes — shallow (10 km depth) offshore earthquakes of magnitude 6.6 can generate local tsunamis near the epicenter. Coastal residents in Vanuatu should follow official tsunami warnings and move to higher ground if they felt strong or long-lasting shaking.

Are aftershocks likely?
Yes. Earthquakes of this size are typically followed by aftershocks, some of which can exceed magnitude 5. This region is already highly active, with at least 28 quakes of magnitude 5.0+ recorded within 300 km in the past year.

How dangerous is a magnitude 6.6 earthquake?
It is a strong earthquake capable of causing significant damage to poorly built or vulnerable structures near the epicenter. Because this quake struck offshore and away from major cities, the risk to large population centers is lower, but nearby island communities face the greatest exposure.
