Academic disciplines Business Concepts Crime Culture Economy Education Energy Events Food and drink Geography Government Health Human behavior Humanities Knowledge Law … This massive symmetrical cone was largely constructed by an accumulation of viscous andesitic lava flows. Bagana volcano contains a sparsely vegetated symmetrical cone, built up mostly of andesitic lava flows. A stop date with "(continuing)" indicates that the eruption was considered to be ongoing as of the date indicated. Pyroclastic deposits are a minor volume of the volcano. It features a 1750-m-high lava cone constructed by an accumulation of viscous andesitic lava flows. The first recorded eruption of Bagana was in 1842, and eruptions since then have been recorded, even during the Pacific War (1940s). Caption by Robert Simmon. McCormick, B. T., Edmonds, M., Mather, T. A., and Carn, S. A. A small lava dome occurs on the north side of the volcano.

Land An overflight of Bagana in August of 1995 revealed lava flows on the southwest flank on the volcano. Bagana was discovered (by westerners, at least – presumably the local population was well aware of the volcano but that rarely counts) as an active volcano in the 1840’s, when it was seen erupting from ships.

This natural-color image reveals a fresh lava flow on Bagana’s eastern flank. It is a small pyroclastic shield truncated by a 2 km wide caldera filled by a crater lake. Fresh lava flows are difficult to distinguish from the barren rock of Tolbachinsky Dol, a volcanic plateau. Bagana continues to erupt small ash explosions from time to time, producing ash plumes that rise to 2.4-3 km altitude and are monitored by the Darwin VAAC. Overlapping lava flows have built the main cone of the volcanic … Despite being one of the most active volcanoes in Papua New Guinea, Bagana is poorly monitored.

The fresh lava is dark brown, while lighter brown areas were likely stripped of vegetation by volcanic debris or acidic gases. Despite its enormous emissions of gas, the typical activity of the volcano is a sluggish effusion of lava flows in eruptions lasting months at a time. Just north-east of Bagana is the volcano crater lake Billy Mitchell. It seems that Bagana is a rare example of a very youthful, polygenetic, andesite volcano. The first known eruption of Bagana was in 1842. Bagana, arguably the most active volcano in Papua New Guinea, has been in a state of near-continuous eruption for over 150 years, with activity dominated by sluggish extrusion of thick blocky lava flows.
