Bagana volcano on Bougainville Island is one of the world's most active volcanoes. It has erupted frequently since its discovery in 1842. It is located on a remote part of central Bougainville Island in the Northern Solomon Province of Papua New Guinea.
Bagana volcano is a massive, symmetrical, roughly 1750-m-high cone built largely by rapid accumulation of viscous andesitic lava flows. The present-day cone might only be 300 years old.
Major eruptions occurred in 1950, 1952, and 1966. Bagana has been in near- continuous activity since 1972, creating slow-moving lava flows, and occasionally ash explosions that sometimes produce pyroclastic flows.
The volcano has been in near-continuous activity since the earliest records from the 18th century. lava cone (stratovolcano) 1750 m / 5,741 ft Bougainville Island, Papua New Guinea, -6.14°S / 155.2°E Current status: minor activity or eruption warning (3 out of 5) Bagana webcams / live data | ReportsBagana volcano booksBagana volcano eruptions:

Monday Aug 29, 2016 10:54 AM | BY: T  Bagana and its plume of gas/ash seen from Terra satellite today (NASA)  MODIS thermal signal from Bagana volcano (MIROVA) Low-level ash emissions occur at the volcano, producing a plume at estimated 7,000 ft (2.1 km) altitude drifting west from the volcano.
The latest Terra satellite image shows a narrow plume of mostly gas and possible light ash content extending about 70 km to the west of Bougainville Island.
A moderate thermal hot spot is visible on MODIS data and has increased recently. This suggests that the volcano's activity (effusive or mildly explosive or both) has picked up recently. Previous news

Darwin VAAC reported several small ash plumes drifting west from the volcano today and during the past days, suggesting that mild eruptive activity continues at the volcano. [more]Monday, May 23, 2016 Mild eruptive activity continues at the volcano. Darwin VAAC reported an ash plume that rose to 7,000 ft (2.1 km) altitude and drifted west yesterday.
