A 6.9-magnitude earthquake struck off the coast of Vanuatu on Saturday, October 24, 2026, triggering a tsunami warning that authorities later lifted after confirming the threat had passed. The Pacific Tsunami Warning Centre revised the magnitude down from an initial 7.2 estimate and declared the tsunami danger over, while a second quake of magnitude 6.3 rattled the same region just minutes later.
What happened and where
The main quake struck at 0231 GMT (1:31 p.m. local time) at a shallow depth of 10 kilometres (6 miles), with its epicentre about 197 kilometres (122 miles) west-northwest of Port-Olry on the island of Santo, according to the U.S. Geological Survey. Some early readings placed the epicentre around 200 kilometres west of Sola, Vanuatu's northernmost town. The Pacific Tsunami Warning Centre initially warned that hazardous tsunami waves were possible for coastlines within 300 kilometres of the epicentre.
A second earthquake, measuring magnitude 6.3, hit at 0235 GMT, only about four minutes after the larger tremor. Its epicentre was approximately 170 kilometres (106 miles) northwest of Port-Olry, also at a depth of 10 kilometres. The USGS assigned the second quake a green alert level, indicating a low likelihood of significant casualties or damage.
Warning issued, then lifted
Vanuatu's Geological Hazards Department had issued a warning telling people in coastal areas to evacuate to higher ground. In a subsequent bulletin issued at 0328 GMT (2:28 p.m. Vanuatu time), the Pacific Tsunami Warning Centre confirmed that the tsunami threat had passed. It noted that minor sea-level fluctuations could still occur in some coastal areas near the earthquake over the following hours, but said no further action was required beyond normal caution near the sea. Authorities in the Philippines and Chile also found no danger to their coastlines.
No damage reported, aftershocks continue
As of publication, there were no immediate reports of casualties or significant damage from any outlet covering the quake. Vanuatu's former prime minister, Alatoi Ishmael Kalsakau, wrote on Facebook that aftershocks were continuing, counting five quakes on Saturday, and urged residents to stay safe and check official apps regularly.
Earthquakes are common in Vanuatu, a low-lying archipelago that straddles the tectonic Ring of Fire, an arc of seismic activity stretching through Southeast Asia and across the Pacific basin. The seismic activity came just days after a 6.4-magnitude earthquake struck the Coral Sea on October 20, highlighting the region's ongoing seismic unrest.

The takeaway: A powerful quake tested Vanuatu's warning systems on Saturday, but the outcome was the best-case scenario — a swift evacuation warning, a lifted tsunami alert, and no reported casualties or damage. With aftershocks still being felt, residents are keeping a close eye on official channels while life on the islands continues.
