Garove is the largest of the Witu Islands, which lie north of New Britain. The low, 12-km-wide elongated island is cut by a 5-km-wide caldera that is flooded by the sea through a narrow breach on the southern side of the island, forming Johann Albrecht harbor. The steep-sided caldera walls rise 100-150 m above the sea. Satellitic cones were constructed along the NE and SW coasts. No historical eruptions are known from Garove, but the preservation of fresh lava flow structures on the NW coast suggests an age as young as a few hundred years (Johnson and Blake, 1972).
The Global Volcanism Program is not aware of any Holocene eruptions from Garove. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Garove page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

|The most prominent feature of Garove Island, located north of New Britain, is a 5-km-wide caldera that is flooded by the sea through a narrow breach on the southern side of the island, forming Johann Albrecht harbor. Satellitic cones were constructed along the NE and SW coasts of the 12-km-wide island. No historical eruptions are known from Garove (also known as Vitu, or Witu), but the preservation of fresh lava flow structures on the NW coast suggests an age as young as a few hundred years. The eastern tip of Mundua Island is visible at the upper left.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
