The Vanuatu subduction zone (previously called New Hebrides subduction zone) is currently one of the most active subduction zones on Earth, producing great earthquakes (magnitude 8.0 or greater), with potential for tsunami hazard to all coastlines of the Pacific Ocean.[2][3] There are active volcanoes associated with arc volcanism.
