BackgroundThe Garua (Talasea) Harbour volcanic field consists mostly of rhyolitic rocks. It consists of lava domes and ash cones and the 2 lava domes of Garua Island, and at least some of the vents might be of Holocene age.
The volcanic vents form a natural harbour open to the east, where it is protected by Garua Island.
Garua is a small densely vegetated volcanic island east of the Willaumez Peninsula. It is formed by 2 rhyolite lava domes which are surrounded by a narrow coastal plain. Many ash layers from nearby Dakataua and Witori volcanoes form distinct tephra layers on Garua island.
