The Gayolesten fumarole field is located on the flanks of the Pleistocene Gunung Kembar volcano. The Kembar complex, located at the junction of two fault systems, is an andesitic shield volcano capped by a complex of craters and cones (Cameron et al. 1982). Gayolesten was included in the Catalog of Active Volcanoes of the World (Neumann van Padang 1951) based on its geothermal activity. Active fumaroles and hot springs are present at several locations.

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

Kembar volcano, the small forested peak at left-center, is seen in this aerial view from the north. The Gayolesten fumarole field is located on the flanks of the Pleistocene Gunung Kembar volcano. Active fumaroles and hot springs are present at several locations. The Kembar complex, located at the junction of two fault systems, is an andesitic shield volcano capped by a complex of craters and cones. The parallel trace of the major Sumatra fault system forms the valley diagonally cutting across the image to south of Kembar.

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.
