Onikobe caldera, located SW of Kurikoma volcano, is one of the few calderas in Japan with evidence of ring fractures and a resurgent dome. The Takahinata lava dome was last active about 350,000 years ago according to a fission-track date. Onikobe was active until about 0.2 million years ago (Nakano et al., 2001-). Geysers were said to be discovered about 1700 years ago at Onikobe, and geysers and hot springs are present today within the caldera.

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

Onikobe caldera is seen here from the SE. Onikobe, located SW of Kurikoma volcano, is one of the few calderas in Japan with evidence of ring fractures and a resurgent dome. Geysers were said to be discovered about 1700 years ago at Onikobe, and geysers and hot springs are present today within the caldera. The snow-capped Chokai volcano is visible on the upper right horizon.

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.
