Tore VulkanTore volcano is a 6 x 9 km wide caldera with a younger cone, which probably is still active.
The densely forested volcano is located north-west of Mount Balbi volcano in the Emperor Range in northern Bougainville Island, Papua New Guinea.
The younger cone of the volcano consists of a thick succession of andesitic lava flows.
Beschreibung:from: Smithsonian / GVP volcano information:
The caldera of Tore volcano is the source of two Pleistocene ignimbrites that form a broad fan that extends the coastline to the west.
The southern and SW sides of the caldera rim are covered by lava flows that extend up to 14 km from a large post-caldera lava cone. The summit of the andesitic volcano consists of an erosional pyramidal peak and a forested satellite ash cone 3 km to the NW. The freshly preserved features of the post-caldera ash cone and lava cone indicate a recent age (Blake and Miezitis, 1967).
