Overview
The Garua (Talasea) Harbour volcanic field consists of a group of lava domes and ash cones of possible Holocene age. These volcanic vents ring the harbor on the west and form Garua Island to the east. Much of the volcanic field, including the two lava domes on Garua Island, consists of rhyolitic rocks.
Active hot springs ring the shores of Garua Harbour and are best developed on the north and south sides. Large boiling pools, fumaroles, and small geysers are found on the north shore near Pangalu village. Another large group of boiling pools, fumaroles, and mudpots is located near the Talasea Government Station on the south shore of the bay.

About the Photo
The Garua (Talasea) Harbour volcanic field (upper right center) consists of a group of mostly rhyolitic lava domes and ash cones that ring the harbor on the west and form Garua Island (right center) to the east. Active hot springs ring the shores of Garua Harbour, including a large group of boiling pools, fumaroles, and mudpots located near the Talasea Government Station on the south shore of the bay, directly opposite the western tip of Garua Island.
