Éruption — Ulawun

Ulawun volcano in Papua New Guinea is actively erupting. Recent satellite observations from the Darwin Volcanic Ash Advisory Centre recorded ash plumes rising to approximately 3.7 km altitude, with ash drifting eastward. The volcano remains in an active eruptive phase as of late July 2026.

If you are currently within approximately 50 km of Ulawun, you may experience ash fall, reduced visibility, and air quality degradation. Ash can affect respiratory health, visibility for transport, and equipment. Monitor local conditions closely and be prepared to adjust your activities or location if ash intensity increases.

Follow guidance from local authorities and the Rabaul Volcano Observatory. Limit outdoor exposure during heavy ash fall, wear protective masks if available, and keep vehicle air filters and windows closed. Stay informed through official channels for any evacuation orders or travel restrictions in the affected area. This alert is based on data from the Darwin Volcanic Ash Advisory Centre and Rabaul Volcano Observatory.
