The 16 x 9 km, shark-tooth-shaped Koro Island, located between Fiji's Viti Levu and Vanua Levu Islands, is part of the volcanic Lomaiviti Islands. A chain of basaltic cinder cones of upper Pleistocene or possibly Holocene age extends from north to south along the crest of the island (Coulson, 1976). With the exception of one location on the west coast where young lava flows reached the sea, the youngest lava flows, erupted from the NNE-SSW-trending cinder cone chain, are confined to the central plateau, where they form a flat, undissected lava field that extends primarily to the east.

The Global Volcanism Program is not aware of any Holocene eruptions from Koro. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Koro page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Koro.

The 16 x 9 km, shark-tooth-shaped Koro Island is located between Fiji's two major island groups. A chain of cinder cones of upper Pleistocene or possibly Holocene age extends along the crest of the island from the NE tip (upper right) to the sharp-pointed southern tip. The youngest lava flows are mostly confined to the central plateau, the flat area around the small weather cloud north of the prominent SE-trending drainage. The flat, undissected lava field extends primarily to the east.

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.

Large Eruptions of Koro Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
WOVOdat WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
EarthChem EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters.
