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).
The Global Volcanism Program is not aware of any Holocene eruptions from Tore. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tore page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The Global Volcanism Program has no synonyms or subfeatures listed for Tore.
|Much of the left side of this NASA image with north to the upper left is covered by volcanic products from Tore volcano in the Emperor Range on NW Bougainville Island. The Tore massif lies to the left of the light-colored area at the center of the image, Balbi volcano. Two Pleistocene ignimbrites from Tore formed a broad fan that extends the coastline to the west (lower left). The dark-colored caldera lake of Billy Mitchell volcano is at the right, above an ash plume originating from Bagana volcano.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
