Overview
Multiple volcanic features and active thermal areas are 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 larger of which is a flat-topped, obsidian-bearing rhyolitic dome.
Six other lava domes are clustered around Salt Lake on the W side of the area. Hot springs, boiling springs, fumaroles, and mud pools are found in an area of siliceous sinter near Iamalele village.

About the Photo
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).
