A major earthquake of magnitude 7.3 struck off the coast of Vanuatu on March 30, 2026. The epicenter was about 35 km (22 miles) northeast of Luganville, the country’s second-largest city. The quake occurred at an intermediate depth of roughly 115–115.8 km beneath the Earth’s surface, which tends to reduce surface damage compared with a shallow quake of the same magnitude.

Both the Pacific Tsunami Warning Center and related agencies reported no tsunami threat from this event, and no tsunami warning was issued. Early USGS impact modeling and news reports indicate the quake likely caused moderate shaking on several islands but was unlikely to cause fatalities or significant economic damage. No immediate serious damage reports have surfaced in the coverage so far.

Vanuatu sits along the Pacific Ring of Fire, one of the most seismically active regions in the world. The earthquake occurred near a subduction zone where the Australian Plate is being forced beneath the Pacific Plate, a process that frequently generates powerful earthquakes in the region.

Aftershocks are expected in the coming days and weeks, some of which could be strong enough to be felt across nearby islands.
