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.

Bagana volcano (Papua New Guinea): ash emissions
Friday Jun 05, 2015 07:58 AM | BY: T
Based on satellite observations, the volcano has produced a number of ash plumes rising to approx. 8,000 ft (2.4 km) altitude, which drifted 40 km to the west. (VAAC Darwin)
A strong heat source has been visible at the crater since 21 May as well. This suggests a new eruptive phase is in course, likely in form of a lava dome extrusion and/or mild strombolian activity.
