The New Hebrides Plate is a minor tectonic plate located in the Pacific Ocean near the island nation of Vanuatu. The plate is bounded on the southwest by the Indo-Australian Plate which is subducting below it. The New Hebrides Subduction Zone is extremely active, producing over 20 earthquakes of magnitude 7 or higher in just the past 25 years. The latest quake occurred on April 9, 2008, with a magnitude of 7.3. The quake occurred 35 km (22 mi) deep, with the epicenter located about 70 km (43 mi) southwest of the island of Tanna in Vanuatu.[1]
