Strong M6.2 earthquake strikes Port-Olry, Vanuatu on October 25, 2026

An M6.2 earthquake was recorded at 02:24 UTC on October 25, 2026, approximately 21 km (13 miles) east of Port-Olry, Vanuatu, at a depth of 136.3 km (84.7 miles).

The event’s epicenter, located at coordinates 167.3°E, 15.0°S, places it near the northern coast of Espiritu Santo island, one of the most populated areas in Vanuatu. Port-Olry is a coastal settlement, and the region is known for its significant seismic activity due to proximity to tectonic boundaries.

Critical infrastructure in the region includes local transport routes, ferry connections, and the nearby Santo-Pekoa International Airport, which serve as vital links between islands and population centers on Espiritu Santo. Ports in the area provide essential connectivity for local residents and commerce.

There is no tsunami threat associated with this earthquake, based on its location and available data.

USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity was IV (4.235), and there was 1 felt report submitted. The significance index is 592 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

Vanuatu lies on the Pacific “Ring of Fire,” an area known for intense seismic and volcanic activity due to the subduction of the Australian Plate beneath the Pacific Plate. The region regularly experiences moderate to strong earthquakes as a result of these tectonic processes.
