The beautiful caldera lake of Billy Mitchell provides a dramatic setting for unvegetated Bagana volcano, one of the most active in Papua New Guinea. The Solomon Sea can be seen in the distance to the SW. Two major explosive eruptions from Billy Mitchell, one about 900 and the other about 370 years ago, produced pyroclastic-fall deposits that cover most of the northern half of Bougainville Island and pyroclastic-flow and -surge deposits that extend 25 km to the eastern coast. The younger eruption may have been responsible for formation of the summit caldera.

Billy Mitchell is a small pyroclastic shield truncated by a small 2-km-wide caldera containing a beautiful caldera lake. It is seen here from the north, with the eroded forested Reini volcano on the center horizon and neighboring Bagana volcano at the upper right. Billy Mitchell has been the source of some of the largest Holocene eruptions of Papua New Guinea. Two major explosive eruptions, one about 900 years ago and the other about 370 years ago, produced pyroclastic-fall deposits that cover most of the northern half of Bougainville Island.

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.
