Kogaja-jima is a small volcanic island located NW of Nakano-shima. The andesitic lava domes were considered to be of late-Pleistocene to Holocene age (Nakano et al., 2001-). Kogaja-jima (Little Gaja Island) lies ESE of the larger Gaja-jima stratovolcano. The 301-m-high Kogaja-jima volcano displays minor fumarolic activity exposed in coastal cliffs.

The Global Volcanism Program is not aware of any Holocene eruptions from Kogaja-jima. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Kogaja-jima 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 Kogaja-jima.

The steep-sided cliffs of Kogaja-jima, a small volcanic island located NW of Nakano-shima, are seen here from the WSW. The andesitic lava domes were considered to be of late-Pleistocene to Holocene age. Kogaja-jima (Little Gaja Island) lies ESE of the larger Gaja-jima stratovolcano. The 301-m-high Kogaja-jima volcano displays minor fumarolic activity exposed in coastal cliffs.

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.
