Bola volcano (or Mt. Wangore) is a symmetrical steep stratovolcano that forms the highest point on the Willaumez Peninsula in New Britain.
There are no known recent eruptions, but the fresh morphology of the summit crater suggests that the last activity was only a few hundred years ago.

Introduction
Except for the upper parts of the slope, the flanks are vegetated. At the ash covered summit, Bola contains a 400 m wide crater with a 100 m steep cliff on the eastern side and almost no inner wall on the western side. There are active fumaroles in the crater.The eastern half of the Bola has steep ash slopes. 3 large explosion craters are located on the lower NE flank. Andesite lava flows are located on the western side of the mountain.
The most recent eruptions were lava flows from the summit crater. The flows are at least 50 m thick, and give the volcano a hump when viewed from the north or south.
