Imun is a single small dacitic and/or rhyolitic cone south of Lake Toba with a youthful, undissected morphology, and is considered to be of late-Pleistocene or Holocene age (Aldiss et al., 1983).

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

The small dark-green area below the center of this NASA Landsat image of NW Sumatra (with north to the top) is Imun volcano. This cone of uncertain age lies south of the renowned large caldera containing Lake Toba (top).

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.
