Tofua is a volcanic island in Tonga. Located in the Haʻapai island group, it is a steep-sided composite cone with a summit caldera. It is part of the highly active Kermadec-Tonga subduction zone and its associated volcanic arc, which extends from New Zealand north-northeast to Fiji, and is formed by the subduction of the Pacific Plate under the Indo-Australian Plate.[2] It lies about 100 km (62 mi) above a very active seismic zone.[3] It is connected to the nearby island of Kao by a submarine ridge.[4]
The island is a national park.
