Overview
- Seismologists first reported a powerful shallow quake on Saturday, Oct. 24, 2026, with early readings up to M7.2 that the USGS later revised to a main M6.9 and a nearby M6.3.
- The Pacific Tsunami Warning Center issued a preliminary tsunami alert for coasts within a few hundred kilometres and Vanuatu’s National Disaster Management Office urged evacuations before canceling the warning after tide-gauge and observational data showed no dangerous waves.
- Initial epicentre estimates placed the shocks roughly 120–220 kilometres from populated Vanuatu islands at about 10 km depth, and scientists noted uncertainty about whether the close-in-time readings were separate quakes or rapid revisions of the same event.
- There were no confirmed reports of casualties or structural damage in the immediate aftermath and local authorities are carrying out damage checks and monitoring for aftershocks.
- Vanuatu sits on the Pacific Ring of Fire where shallow quakes are common, so officials will keep relying on fast magnitude updates and sea-level sensors to guide any future evacuation orders and public warnings.
