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).
