Volcanoes have helped shape our planet. Older lava flows are covered in light green vegetation, and the surrounding forests are dark green. What caused Bagana to form and what kind of damage did it do? It is a small pyroclastic shield truncated by a 2 km wide caldera filled by a crater lake. Located on the mountainous spine of Bouganville Island, it is both far from any cities or large towns and hard to reach due to the rough terrain. The first known eruption of Bagana was in 1842. Bagana is one of seven active volcanoes on Papua New Guinea’s Bougainville Island.

Since then there have been at least 22 eruptions. Bagana emits volcanic gases (including water vapor and sulfur dioxide) almost continuously, and frequently extrudes thick lava flows. The volcanic plume and clouds are both white. Billy Mitchell is a volcano in the central part of the island of Bougainville, just north-east of the Bagana Volcano in Papua New Guinea. We consider the possibility that, as a result of this eruption, the magma supply was diverted from Billy Mitchell to Bagana. Bagana erupts a slow moving, blocky lava, in flows which can last for months or even years. INTRODUCTION Long-lived eruptions from silicic volcanoes are a common and hazardous mode of volcanism.
