Six kilometres NNW of Bagana, an andesite-dacite volcano, Billy Mitchell, had a large, caldera-forming plinian eruption 437 years ago. Bagana emits volcanic gases (including water vapor and sulfur dioxide) almost continuously, and frequently extrudes thick lava flows. Bagana is a large cone, and one of Melanesia’s youngest and most active volcanoes. The first known eruption of Bagana was in 1842.
