Garua (Talasea) volcano (or Garua Harbour volcano) is a volcanic field on the Willaumez Peninsula in New Britain, Papua New Guinea.
It has abundant geothermal activity with hot springs, large boiling pools, fumaroles, and small geysers, in particular along the shores of Garua Harbour and on the north shore near Pangalu village. Mudpots occur near Talasea on the south shore.

Introduction:

The 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 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.
