The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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.

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.
