Gunung Ungaran volcano, south of the northern coastal city of Semarang, lies at the northern end of a transverse chain of Java volcanoes extending NNW from Merapi. Ungaran was formed in three stages, with growth of the youngest edifice taking place during the late Pleistocene and Holocene. The youngest Ungaran edifice was constructed south of three large remnant structural blocks of the 2nd Ungaran volcano. A group of pyroclastic cones was also constructed along the margins of the older volcano. Ungaran is deeply eroded and no historical eruptions have been reported, but two active fumarole fields are located on the volcano's flanks.

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

Gunung Patah is a densely forested, dissected Quaternary volcano SE of Dempo volcano (upper right). The location of a possible new crater first observed in 1989 about 6 km SE of the summit is shown by an arrow in this photo.

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.
