Rajabasa is a prominent, isolated volcano along the Sunda Strait at the SE-most tip of Sumatra. The low, 1281-m-high conical volcano has a well-preserved 500 x 700 m summit crater with a swampy floor. The age of its most recent eruptions is not known, although fumarolic activity occurs on the foot and flanks of the volcano. Increased activity was reported in April 1863 and May 1892.

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