Vanuatu offshore earthquakes trigger tsunami warning

A series of powerful earthquakes struck the waters near the Vanuatu archipelago in the South Pacific on October 24, 2026. The United States Geological Survey (USGS) initially reported a preliminary magnitude of 7.2, but later revised the primary event to a magnitude 6.9. This main tremor occurred at a shallow depth of approximately 10 kilometers, roughly 197 to 200 kilometers west-northwest of Port-Olry.

Less than five minutes after the initial shock, a second earthquake measuring magnitude 6.3 was recorded in the same maritime region. The Pacific Tsunami Warning Center (PTWC) issued a localized tsunami warning for coastal areas within a 300-kilometer radius of the epicenter. However, the alert was subsequently lifted after authorities monitored sea levels and determined that a significant tsunami threat no longer existed.

Following the primary events, the region experienced continued seismic activity, including a magnitude 6.1 earthquake on October 25 at a depth of 141 kilometers. While the initial tremors caused significant concern, there were no immediate reports of casualties or major structural damage resulting from the offshore activity.
