Powerful 6.9-Magnitude Earthquake Strikes Near Vanuatu, Tsunami Warning Lifted

A powerful earthquake struck offshore near the South Pacific island nation of Vanuatu on Saturday, October 24, prompting authorities to issue a temporary tsunami warning before later withdrawing it.

The United States Geological Survey initially reported the earthquake at magnitude 6.9, with its epicentre approximately 197 kilometres west-northwest of Port Olry and a depth of around 10 kilometres. Some early reports gave a slightly different magnitude as estimates were updated.

Tsunami warning issued and lifted

The earthquake triggered concern about possible tsunami waves across parts of the Pacific. A tsunami warning was issued for the surrounding area, but the warning was subsequently rescinded.

Officials assess tsunami risks by examining an earthquake’s magnitude, depth, location and the possibility of significant movement of the seafloor. Not every large earthquake produces a destructive tsunami, but warnings are issued when conditions indicate a potential threat.

Authorities monitor aftershocks

Additional seismic activity was recorded after the main earthquake. Aftershocks are common following major earthquakes and can occur over hours, days or longer.

Authorities and monitoring agencies continued tracking the seismic activity. Initial reporting indicated that there were no immediate reports of damage, although assessments can take time, particularly in island communities that are difficult to reach.

Why Vanuatu is vulnerable

Vanuatu lies in the seismically active Pacific region, where the movement of tectonic plates produces frequent earthquakes. The country’s island geography also means that offshore earthquakes can raise concerns about coastal hazards and tsunami impacts.

Residents in earthquake-prone areas are advised to follow official emergency guidance, move away from coastal areas if instructed and avoid relying on unverified social media claims during an emergency.

What happens next?

Monitoring agencies will continue reviewing earthquake measurements and tracking aftershocks. The initial magnitude may be revised as additional data is analysed.

Although the tsunami warning was lifted, the event highlights the importance of early-warning systems and public preparedness across the Pacific.
