Bola

성층화산 · Papua New Guinea · 1116m

Conical Bola volcano (also known as Wangore) rises to the NW across Stetin Bay. The symmetrical stratovolcano is located immediately SW of Dakatau caldera and forms the high point of the Willaumez Peninsula in central New Britain. The forested cone has a well-preserved, 400-m-wide crater. No historical eruptions have been documented from Bola, but its morphology suggests very recent activity.

Bola volcano (also known as Wangore) is a symmetrical stratovolcano located immediately SW of Dakataua caldera on the Willaumez Peninsula. The forested andesitic cone has a 400-m-wide crater with a 100-m-high eastern wall and a low western rim. Three large explosion craters occupy the NE flank. The most recent lava flow issued from the summit crater and flowed to the west. This viscous flow is at least 50 m thick, leaving an irregularity in the profile of the volcano. The summit crater morphology and weak fumarolic activity suggested to Lowder and Carmichael (1970) that the most recent eruption may have been only a few hundred years ago.
