The latest from across Bougainville

Update 1/2026: Mt Bagana volcanic activity

Mount Bagana began emitting elevated levels of ash and smoke at 11:58pm on Friday, 19 June. The Rabaul Volcanological Observatory (RVO) issued a Level 1 Alert and advised communities in the vicinity of the volcano to remain vigilant.

This activity followed two earthquakes recorded to the west of the Autonomous Region of Bougainville earlier in the week.

South‑easterly winds carried ash across villages in the Rotokas Constituency (Wakunai District) and into Sirivai and Atsinima in Torokina District. Thin layers of ash were observed on rooftops and vegetation. While rainfall has been minimal, any future rain poses a risk of washing ash into household water catchment systems and contaminating water tanks. Ash has also entered rivers, creeks, and rainwater systems.

The assessment mission confirmed widespread ashfall across affected areas. Although ashfall has since subsided, WASH concerns remain the most critical issue, particularly as El Nino conditions emerge and rainfall continues to decline.

Food crops have also been affected, with leafy vegetables being the most vulnerable. There are concerns regarding reduced market value and consumption due to ash contamination.

In response, the Department of Community Government & District Affairs (DCGDA) Disaster Office deployed an assessment team to Ruruvu and Togorau, and coordinated with Torokina District Administration for updates from affected communities.

The Department of Health’s WASH advisories were disseminated and observed in practice, including disconnection of water pipes from tanks and the brushing of ash from rooftops. Health facilities were encouraged to maintain heightened vigilance.

The mission also noted non‑functional WASH infrastructure in Ruruvu due to vandalism and lack of repair. While protected spring sources exist, households must carry water over considerable distances.

All schools in the Rotokas Constituency and the five schools in Torokina have been affected. These areas had already experienced 4–5 weeks without rainfall prior to the ashfall. Communities remain additionally vulnerable due to non‑functional telecommunications and limited electricity.

The Department of Health is continuing assessments, including engagement of the WASH unit.

The DCGDA-Disaster & Emergency Directorate will continue monitoring the situation in coordination with RVO and Geo-Hazards and will provide further updates to the public.
