An area of youthful volcanism and active thermal fields is located on the SW part of Fergusson Island, in the center of the D'Entrecasteaux island group. The Iamalele-Fagululu area contains a series of lava domes and lava flows of probable Holocene age in association with abundant hot springs and fumaroles (Smith 1981). Two small lava domes are located near Fagululu village, the largest of which is a 150-m-high flat-topped, obsidian-bearing rhyolitic dome. Six other lava domes are clustered around Salt Lake on the western side of the area. Hot springs, boiling springs, fumaroles, and mud pools are found in an area of siliceous sinter near Iamalele village.
The Global Volcanism Program is not aware of any Holocene eruptions from Iamalele. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Iamalele 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.

|Late Cenozoic volcanic rocks cover much of the Kukuia Peninsula (left-center) on the SW side of Fergusson Island and areas north of the peninsula. The Iamalele-Fagululu area, located north of the peninsula and south of the Mailolo metamorphic block forming the NW tip of the island, contains a series of lava domes and lava flows and abundant hot springs and fumaroles. Eight small lava domes are located near Fagululu village and around Salt Lake. Young volcanic rocks are also present on Goodenough Island (upper left).

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.
