An area of extensive basaltic lava flows occupies a graben, the NNE-SSW-trending Ch'uga-ryong rift, that cuts diagonally across the demilitarized zone between North and South Korea. One 40-km-long lava flow originated from the low Ap-san shield volcano, which has a 200-m-wide summit crater and more than 20 satellitic cones. Another voluminous late-Pleistocene lava flow is 60 km long. Alkaline basaltic lava flows at the SW portion of the rift were erupted over Precambrian sediments and igneous rocks, and were estimated by Lee (1981) to be late-Pleistocene or early Holocene in age.

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