Rotuma Group
The Rotuma Group is a group of volcanic islands, with Rotuma, Rotuma Island being the main island, located at , approximately 465 km north of Fiji. There are some islands located at a distance between 50 m and 2 km from the main island, but still within the fringing reef: Solnohu (south), Solkope (southeast), Afgaha (far southeast), Rotuma#Geography and geology, Husia (close southeast), as well as Hạua and Hạuameaʻmeʻa (close together northeast). Additionally, there is a separate chain of islands between three and six km northwest and west of the westernmost point of Rotuma Island. From northeast to southwest, those are Uea, Hạfhai with nearby Hạfhahoi, Hạfhaveiaglolo, Hatana and Hạfliua. The islands have an aggregate area of 44 km2, of which the main island Rotuma occupies 43 km2. Only the main island is permanently inhabited.

Volcanic Island
Geologically, a volcanic island is an island of volcanic origin. The term high island can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs (which have often formed on sunken volcanoes). Definition and origin There are a number of volcanic islands that rise no more than above sea level, often classified as islets or rocks, while some low islands, such as Banaba, Henderson Island, Makatea, Nauru, and Niue, rise over above sea level. The two types of islands are often found in proximity to each other, especially among the islands of the South Pacific Ocean, where low islands are found on the fringing reefs that surround most volcanic islands. Volcanic islands normally rise above a hotspot or subduction zone. Habitability Volcanic islands usually range in size between . Islands above a certain size usually have fresh groundwater, while low islands often do not, so volcanic islands are more ...
