"A 6 x 9 km caldera at Tore volcano in the Emperor Range on NW Bougainville Island 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 satellitic 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)."  -Smithsonian Volcano Archive
