Bagana volcano, occupying a remote portion of central Bougainville Island, is one of Melanesia’s youngest and most active volcanoes. Bagana volcano is a massive, symmetrical, roughly 1750-m-high cone built largely by rapid accumulation of viscous andesitic lava flows. It is located on Bouganville Island, one of the Papua New Guinea islands, far from near by cities or large towns. Satellites provide the most reliable way to watch this activity. The entire edifice could have been constructed in about 300 years at its present rate of lava production. Earthquakes and ash emissions continued until April. It is especially unique since loud, violent eruptions have been recorded at Bagana, yet this is not its primary eruption style. Eruptive activity is frequent and … The entire edifice could have been constructed in about 300 years at its present rate of lava production. The family resemblance involves viscous, cool lava with large crystals, long-lasting (months to years) cycles of lava flows and dome building, with the latter leading to explosions, and high outgassing even when the volcano is not erupting. This massive symmetrical cone was largely constructed by an accumulation of viscous andesitic lava flows. Bagana is one of most explosive volcanos in it's country.
