Geologic Summary. Bagana volcano, occupying a remote portion of central Bougainville Island, is one of Melanesia's youngest and most active volcanoes. Bagana is a massive symmetrical lava cone largely constructed by an accumulation of viscous andesitic lava flows. The entire lava cone could have been constructed in about 300 years at its present rate of lava production. Eruptive activity at Bagana is characterized by non-explosive effusion of viscous lava that maintains a small lava dome in the summit crater, although explosive activity occasionally producing pyroclastic flows also occurs. Lava flows form dramatic, freshly preserved tongue-shaped lobes up to 50-m-thick with prominent levees that descend the volcano's flanks on all sides.

29 March-4 April 2006

During 16 February to 31 March, activity at Bagana was at moderate levels. Mostly gas emissions occurred, but on 27 March an ash cloud was emitted. During 15-31 March, observers noted moderate-to-bright incandescence, projections of lava fragments, and a lava flow traveling down the volcano's SSW flank.

21 September-27 September 2005

Ash was emitted from Bagana during 17-18 September and drifted W and NW. During 14-18 September, incandescence from the volcano was visible at night. On the 18th, observers described what could have been cascading volcanic material detached from a possible active lava flow.

17 August-23 August 2005

During 15-21 August, volcanic activity at Bagana remained at low levels. Variable amounts of thick "white vapor" were emitted from the summit crater. During several nights, dull-to-moderately bright incandescence was visible. On the 20th, lava flowed from volcano's main crater. Incandescent lava avalanches occasionally originated from unstable areas of the lava flow.

Based on information from the US Air Force Weather Agency, the Darwin VAAC reported that an ash plume from Bagana was visible at a height of ~3 km (10,000 ft a.s.l.), extending ~40 km SW of the summit. The Darwin VAAC did not see ash on satellite imagery.

A plume from Bagana was observed on satellite imagery on 7 June initially extending 65 km WSW, then W later in the day. The height of the plume was not known.

11 May-17 May 2005

Satellite imagery taken at 0551 on 13 May revealed a thin plume extending 28 km (15 nm) ESE below 3 km altitude (10,000 feet). Similar plumes, blowing W, were identified at 0537 on the 14th and at 0634 on 15 May.

28 April-4 May 2004

According to a news article, following the emission of new lava from Bagana on 27 April, local volcanologists and a team of provincial disaster delegates conducted an aerial inspection of the area around the volcano on 2 May. The team concluded that the lava flows were not an immediate threat to the safety of villagers near the volcano. A spokesperson for Papua New Guinea's national Disaster Center reportedly said, "the aerial inspection team noted a continual effusion of lava flowing in a south-westerly direction but there is a lot of vegetation in the area which is acting as a buffer."

21 April-27 April 2004

A helicopter pilot reported to RVO that new lava was being emitted from Bagana around 1240 on 27 April. According to information from the village of Torokina, the lava flow was estimated to be about 8-9 km from the village. RVO was uncertain about the local topography between the volcano and Torokina, and therefore could not assess the degree of danger for the residents of the village from the lava flow. RVO has no monitoring equipment at Bagana.
